As ESTEC Ltd runs its FTIR promotion, here a few things to note about the equipment.
First, Fourier Transform Infrared Spectroscopy is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid, or gas and in the process identify known and unknown materials/samples by utilizing Infrared Electromagnetic Radiation. An FTIR spectrometer simultaneously collects high-resolution spectral data over a wide spectral range giving it an advantage over conventional spectrophotometers.
In principle, the molecules vibrate, bonds stretch and bend when they absorb IR Radiation. This is done by passing a beam of IR light through a sample. Some of this light will be reflected while others will be absorbed by the sample and consequently specific light will travel through the sample carrying molecular information of the sample. The transmitted light then goes through a detector where the information is interpreted and transformed to a spectrum (sample spectrum). This is achieved by the Fourier Transform mathematical process hence the acronym FTIR. Identification occurs when the sample spectrum is compared to a reference/known spectrum. I know you want to ask how it happens and/or where the known spectrum is. Well wonder not…
All our FTIRs come with LabSolutions IR – An analytical Data system for FTIR. LabSolutions IR is furnished with a rich Spectral Library (Approx. 12,000 spectra of organic compounds, polymers, pharmaceutical products, inorganic compounds, food additives, contaminants, etc.) and a High-performance search function as standard.
We also offer, with our FTIR’s, Attenuated Total Reflectance (ATR) Accessory – Single-Reflection Accessory with a Diamond Crystal. The accessory enables the measurement of a wide variety of samples regardless of their form or properties. I.e., Solids, Liquids, and gels in the mid and far-infrared. Measurement is made without destroying the sample as no sample preparation is required.
As conveyed in the posters, the choice of a particular Model depends on your application, and If I may add, your future needs.
Look at the table below showing the Differentiation between our FTIR series based on customer needs.
|Wavenumber Expansion||Suitable for customers with absorption of the desired component in the near or far infrared regions||Suitable for customers who analyze only in the mid-infrared region||Suitable for customers who analyze only in the mid-infrared region|
|Contaminant Analysis||Suitable for customers who want to connect infrared microscope to analyze minute foreign matter or plan to add infrared microscope in the future||Suitable for customers who want to connect infrared microscope to analyze minute foreign matter or plan to add infrared microscope in the future||Suitable for customers who do not plan to connect infrared microscope to analyze foreign matter up to the size that can be handled.|
|High Sensitivity||Suitable for customers who want to analyze with a highly sensitive MCT detector – used when analyzing minute or low transmittance samples.||Suitable for customers who do not require an MCT detector||Suitable for customers who do not require an MCT detector|
|Go for if you are…||Research, Academic, Forensic, Environment||Research, Academic, Forensic, Environment||Pharma|
These are just but a few points, talk to us for more details, we are happy to advise on the model that will best suit your application.
And In addition to the above, please note that we have two more new models; IRXross and FTIR Plastic Analysis System.
The Plastic Analyzer method package includes an FTIR spectral library for plastics degraded by UV rays and heat. Utilizing searches of this library demonstrates its effectiveness in the analysis of unknown samples that are difficult to identify with standard libraries. Examples include plastics degraded by exposure to UV rays as well as contaminants and defective items altered by heating.
The IRXross is a mid-level FTIR developed by downgrading IRTracer-100. Performance is almost the same as IRTracer-100 except for wavenumber expandability and S/N ratio which is 55,000:1.
Till next time…..
