I am indebted to Shimadzu for selecting me amongst the users of Shimadzu GC-MS equipment across the globe as a runner up for this campaign. The use of Shimadzu triple quadrupole gas chromatography-tandem mass spectrometry with its information-rich content and explicit confirmation has enabled us to obtain excellent results in food safety, environment monitoring and forensic toxicology. I am privileged for this and looking forward to continue my journey of mass spectrometry with Shimadzu as before with more enthusiasm and ambition.
“Shimadzu GC-MS analytical results that have contributed to society”
Analysis with Shimadzu instruments
The increasing public concern about pesticide contamination of food and the environment in recent years has increased the demand for broader and stricter pesticide monitoring. This requires an effective analytical technique for the simultaneous determination of pesticide residues to protect consumers and guarantee the safety of agricultural products.
This study was aimed at determination of pesticide residues in cucumber using a GC-MS/MS with QuEChERS method in sample preparation. The use of Shimadzu triple quadrupole gas chromatography-tandem mass spectrometry (GCMS-TQ8040) with its information-rich library enabled excellent results to be obtained, thanks to its wonderful sensitivity and selectivity with helium carrier gas at a constant flow of 1mL/min. Pesticides were identified according to their retention times and target and qualifier ions, based on the peak area ratio of the targets to that of internal standard.
