Touching What Moves Mountains

In life, there’s often one thing that holds the power to move mountains, for me, that has always been education. Thankfully, this passion perfectly aligns with ESTEC’s corporate philosophy.

Recently, while reviewing our case studies in the Education sector ahead of engagements with several institutions, two remarkable projects caught my attention, JKUAT’s Food Fortification Laboratory and Kenyatta University’s National Phytotherapeutics Research Centre (NPRC) Lab. These are not just facilities; they are transformative initiatives that showcase the limitless potential of collaboration between Education and Industry. Let me tell the story of the JKUAT Food fortification lab.

The JKUAT Food Fortification Lab – A Case of Science Saving Lives

Food fortification is the deliberate addition of essential vitamins and minerals to commonly consumed foods. Following national surveys that revealed rising malnutrition rates, especially among women and children, the Kenyan government passed legislation in 2012 making fortification mandatory for staple foods like packaged maize flour, wheat flour, and edible oils.

To anchor this massive effort, the European Union funded the establishment and equipping of the Kenya National Food Fortification Reference Laboratory at JKUAT. This facility plays a central role in fortification monitoring, regulation and compliance with national standards.

And yes, you guessed it, ESTEC was part of this impactful story. We proudly equipped this state-of-the-art laboratory, The other key stakeholders in this program such as Kenya Bureau of Standards (KEBS) and National Public Health Institute (NPHI) are both valued ESTEC clients.

The Impact Beyond the Lab

By now, many of us have done or are planning our monthly household shopping. I can bet you passed by the maize flour or wheat flour shelves and picked your favorite brand; Soko, Jogoo, Mama, Pembe, or perhaps the newer one, Lea.

Now, look at the packaging. You’ll see a fortification logo and a declaration of essential nutrients like Zinc, Iron, and various Vitamins. But here’s the critical question: How do regulators and manufacturers prove these nutrients are present in the required, life-saving amounts?

That’s where ESTEC comes in.
We supply the analytical solutions,(technology and expertise) that make this verification possible, ensuring every meal contributes to a healthier, safer population.

Now that we’re on “kitchen matters,” it’s worth noting that our vision “A Safe and Healthy Africa” wasn’t just coined by a kitchen cabinet to suit this story. It’s a daily commitment that guides every solution we provide across sectors.

The Science Behind Assurance

To test essential minerals like Iron and Zinc, laboratories rely on advanced analytical equipment like Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Vitamin A analysis is performed using a UV-VIS Spectrophotometer.

In this context, it’s not just about nutrition. Contaminants like Aflatoxin must also be monitored using instruments like High-Performance Liquid Chromatography (HPLC),a topic for another day!

Beyond supplying and installing this sophisticated technology, we provide reliable technical support. We know that prolonged downtime in this lab could literally mean meals across the country lack essential nutrients. The stakes are immense.

The Measurable Impact

It’s always satisfying when data reveals the fruits of scientific collaboration. At a stakeholder meeting last year, Prof. Daniel Sila, Principal at JKUAT’s College of Agriculture and Natural Resources and a key architect of the Food Fortification Lab, shared encouraging results:

“The efforts have enhanced fortification compliance among maize millers from 16% in 2018 to 45% currently. Compliance among wheat millers has also improved from 18% to 85% over the last five years.”

Such milestones remind me why I’m deeply passionate about what I do. Behind such statistics lies a story of improved health, better nutrition, and transformed lives.

Looking Ahead – Where Education Meets Industry

While this article highlights just one stream of collaboration, there are countless others waiting to be explored. Educational institutions hold immense potential to serve as research and innovation platforms for industry players fostering a continuous exchange of ideas, expertise and solutions.

Because when Education and Industry work hand in hand, we don’t just move mountains we build a healthier, safer and more resilient Africa.

Now, let me go and boldly share this story during my presentations with the institutions that inspired this reflection.

Moisture & Water Content Testing: Why It Matters More Than You Think

Water is essential for life — but in manufacturing, even a drop too much (or too little) can ruin a product. From pharmaceuticals to fuels, the moisture content of raw materials and finished goods directly affects performance, safety, shelf life, and compliance.

Moisture content impacts:

  • Quality → texture, stability, and usability.
  • Safety → microbial growth, corrosion, chemical reactions.
  • Compliance → meeting pharmacopeia, ISO, or ASTM standards.

That’s why moisture and water content testing isn’t just a lab exercise — it’s a critical quality checkpoint.

What Is Moisture/Water Content Testing?

Moisture testing determines the exact water level in a product, whether solid, liquid, or powder. This can be expressed as a percentage, in parts per million (ppm), or in other units depending on the application.

While the concept sounds simple, the stakes are high:

  • Too much water can trigger microbial growth, corrosion, unwanted chemical reactions, or product instability.
  • Too little water can alter texture, reduce efficiency, or even cause a product to fail its intended purpose.

For regulated industries, wrong measurements can risk compliance audits or recalls.

Why Moisture Testing Matters — Industry by Industry

Every industry has its own reason for moisture control. For instance, a capsule in pharma must have tightly controlled water levels for potency. In food, excess moisture can cause mold and spoilage. In petroleum, even ppm levels of water can corrode engines. Cosmetics must maintain texture (no drying out or separating), while environmental testing relies on water content to guide agriculture and waste management.

The goal is always the same: control, consistency, and compliance.

  • Pharmaceuticals – Guarantee drug potency and stability, ensuring compliance with pharmacopeia standards.
  • Food & Beverage – Prevent spoilage, ensure safety, and meet strict labeling requirements.
  • Petroleum & Lubricants – Detect contamination that can cause corrosion, reduce performance, or destabilize fuels.
  • Chemicals & Polymers – Maintain product uniformity, prevent hazardous reactions, and streamline manufacturing.
  • Cosmetics & Personal Care – Preserve texture, stability, and shelf life while meeting consumer expectations.
  • Environmental Testing – Monitor soil, sludge, and waste moisture levels for sustainability and agricultural planning.

How It’s Done — Precision Matters

The right method depends on your product, regulations, and desired accuracy.

  • Loss on Drying (LOD) → involves heating a sample until weight stabilizes. It’s quick but may measure volatiles other than water.
  • Infrared methods  → non-destructive and rapid, ideal for production checks, but often require calibration.
  • Gravimetric methods  →  traditional, widely used in food testing, but can misrepresent actual water levels.
  • Karl Fischer titration  → globally recognized for pinpointing even trace moisture down to 1 ppm with high precision — making it the preferred method where regulations demand accuracy.

👉 While other methods have their place, Karl Fischer is the industry choice when compliance and precision matter most.

Our Solutions — SI Analytics TitroLine® Titrators

We offer KF titration solutions tailored for all industries.

  • TitroLine® 7500 KF Trace → Ultra-low water detection (1 ppm to 5%). Perfect for petroleum, pharma, and specialty chemicals.
  • TitroLine® 7500 KF → Flexible volumetric testing for a wide range of samples — % water or ppm.
  • TitroLine® 7000 → Multipurpose titrator: water content plus non-aqueous titrations (like TAN/TBN in oils).

Our instruments are designed for both routine QC labs and specialized R&D environments. Whether you’re checking trace moisture in fuels or % moisture in powders, the TitroLine® range provides precision, compliance, and flexibility.

Choosing the Right Testing Instrument

The best choice depends on:

  • Moisture range (trace ppm vs percentage)
  • Sample type (solid, liquid, oil, powder, gas)
  • Precision & compliance needs (pharma, ISO, ASTM, etc.)
  • Automation level (manual vs integrated systems)

No two labs have the same needs. For a petroleum lab following ASTM standards, the 7500 KF Trace is ideal. A pharma lab needing % water and trace detection may choose the 7500 KF. For labs handling oils, the 7000 adds flexibility for TAN/TBN titrations alongside water determination.

Final Word

Moisture testing is not just another step — it’s a safeguard for:

  • Product quality
  • Regulatory compliance
  • Your brand’s reputation

💡 When accuracy matters, Karl Fischer titration is the gold standard — and SI Analytics TitroLine® titrators deliver it with confidence.

Understanding Karl Fischer (KF) Water Determination

Karl Fischer (KF) titration is widely recognized as the most selective and precise method for determining water content in various samples. This method offers two primary techniques: volumetric and coulometric titration.

Volumetric Method

In the volumetric method, iodine is precisely added using a piston burette. This method is suitable for analyzing liquid, solid, or gaseous samples. By selecting the appropriate KF reagents and adjusting conditions like temperature or using a disperser, accurate water content determination can be achieved across a range of sample types.

Coulometric Method

The coulometric method generates iodine directly within the titration vessel, enabling the detection of very low water concentrations. An advantage of this method is that there is no need to determine the concentration of the titrant. For direct titration in glass vessels, samples must be liquid or gaseous. Solid or highly viscous samples require external dissolution or extraction, which can be done using equipment like the TO 7280 headspace oven or TO 7280/TW 7650 oven with autosampler.

The Journey From Tunic Dresses to Chromatographic Columns

Transitioning from primary to secondary school in the 8-4-4 education system can feel like stepping into a whole new world. For me, it wasn’t just about the academic leap; trading my comfy tunic dress for a skirt and blouse symbolized a rite of passage. It was more than fabric; it was about stepping into the next chapter of life, full of adolescent attitudes and a newfound autonomy.

Fast forward through the initial rollercoaster of secondary school, where likes and dislikes for teachers were as fluctuating as our moods. The first four terms were a mix of adaptation and self-discovery. By the fifth term, amidst the whirlwind of young adulthood, I stumbled upon my passion – Chemistry. It was not just another subject; it felt like a calling. That realization shaped my academic path and led me to cherish my chemistry grades.

Post-high school, I dove into college with an enthusiasm for Chemistry that felt like being handed the controller to your favorite video game and told you could play all day. Imagine that! The thrill of the experiments, the allure of the unknown, and the satisfaction of discovery were intoxicating.

However, the transition from college to the real world was a reality check. While some of my peers secured jobs right out of college, I found myself in the “waiting” category, juggling various hustles. But, as fate would have it, I eventually landed my first job. Imagine getting an ice cream on the sunniest of days – that was the feeling!

Now, let’s talk about the real shocker – chromatography. Studying it in theory was one thing; facing an HPLC (High-Performance Liquid Chromatography) system was another. My college practical hadn’t ventured beyond direct titrations. The first time I saw an HPLC, I was baffled. And when it came to handling a chromatographic column, well, that’s a comical tale of trial and error.

Chromatography hinges on the stationary phase, often a silica-packed column. This segues into a fascinating bit of chemistry trivia. Ever heard of a BDS column? Before you rush off to Google, let me share the scoop. BDS stands for Base Deactivated Silica. It’s a type of reverse-phase HPLC column where the hydroxyl groups are blocked or deactivated. This makes them especially useful for certain types of chemical analyses.

So, from swapping school uniforms to decoding the mysteries of chromatography, my journey has been a blend of personal and academic evolution. And in the spirit of sharing knowledge and experiences, I hope this little “Did You Know?” moment adds a fun twist to your day, just as Chemistry has to mine.

 

BDS (Base Deactivated Silica) columns are widely used in reverse-phase high-performance liquid chromatography (HPLC). These columns are specifically designed for separating non-polar and moderately polar compounds based on their hydrophobic interactions with the stationary phase.

The primary characteristic of BDS columns is the deactivation of hydroxyl groups on the silica surface. These hydroxyl groups, if left active, can interact with polar analytes, leading to undesirable interactions and peak tailing. By deactivating these groups, BDS columns minimize unwanted interactions with polar compounds, resulting in sharper peaks and improved resolution.

The deactivation is achieved by blocking or capping the silica surface with hydrophobic functional groups, typically octadecyl chains (C18). This modification creates a hydrophobic stationary phase that interacts favorably with non-polar analytes, facilitating their separation.

The term “endcap columns” refers to the additional capping of residual silanol groups at the end of the silica chain, further reducing undesirable polar interactions. End capping enhances the column’s stability and reproducibility, particularly at low pH conditions, where silanol groups may become more reactive.

BDS columns find applications in various fields such as pharmaceuticals, environmental analysis, food and beverage testing, and biochemical research. They are particularly useful for separating complex mixtures of organic compounds, including drugs, natural products, and metabolites.

In summary, BDS columns offer improved chromatographic performance by deactivating hydroxyl groups on the silica surface, thereby minimizing unwanted interactions with polar analytes. This makes them essential tools in modern analytical chemistry for efficient separation and quantification of a wide range of compounds.
