Pol.Lt.Gen. Pornchai Suteerakune, Director of NIMT, together with Dr. Kittiya Shearman, Head of the Chemical Metrology and Biometry Department, Dr. Cheerapa Boonyakong, Group Leader of Organic Analysis, and Dr. Jintana Nammoonnoy, metrologist from the Chemical Metrology and Biometry Department, warmly welcomed Ms. Haznita Rose Bahari and Ms. Siti Nor Fadhilah Sulaiman, chemists from the Department of Chemistry Malaysia (KIMIA) for the training on Isotope Dilution Mass Spectrometry (IDMS), which was held from 19 to 30 May 2025 at NIMT.
This training aimed to provide an in-depth study on the determination of preservatives in food using exact-matching ID-LC-MS/MS, with an emphasis on enhancing the capabilities in the detection and quantification of toxic elements in food products. The detailed program included the following key topics:
- Lecture on fundamentals of the exact-matching IDMS
- Standard and labeled standard preparations
- Determination of benzoic acid in food by calibration curve
- Determination of benzoic acid in food by exact-matching ID-LC-MS/MS
- Data processing and calculations
- Estimation of uncertainty
- Summary
The achievement of this course will be mutually beneficial, promoting the exchange of technical and scientific expertise while significantly enhancing the technical capabilities of both institutes. Most importantly, it fosters collaboration and strengthens international networks among chemical metrologists to advance measurement traceability in the fields of chemistry and biometry.
