Webinar on Pesticide Residue Analysis with Advanced GC-MS methods
New Webcast in short format @ 9:30 pm (Indian Standard Time) by Dr. Kaushik Banerjee & Laura Bush.
Analysis of pesticide residues in food and environmental samples in compliance with international regulations is quite challenging, particularly as regulatory requirements are becoming increasingly stringent in most countries. When performing multiresidue analysis, scientists often grapple with problems such as co-elution, matrix effects, and false positives, among others.
This presentation will discuss state-of-the-art gas chromatography mass spectrometry (GC-MS) techniques for precise and accurate analysis of pesticide residues in various matrices. It will cover how, with the use of triple quadrupole instruments, more than 300 compounds can be easily analyzed by a single GC–MS-MS run with a high degree of selectivity along with the mass acquisition based on ultraselective reaction monitoring transitions, which offers higher selectivity and lower limits of quantification. We will also highlight an application of low pressure GC-MS where the typical conventional GC-MS run time of 40–50 min was reduced to less than 15 min without losing chromatographic resolution. In addition, we will discuss how the hyphenation of GC to an atmospheric pressure ionization source facilitates unambiguous identification of target compounds (such as captan and iprodione), which produce nonspecific mass spectra in EI-GC-MS.
