New IC & IC–MS solutions for the Cationic Polar Pesticides and Related Highly Polar Amine Analytes

Pesticides are the chemicals that provide the modern food abundance.  Highly polar pesticides find widespread use, yet their detection and reliable quantitation in foods at trace levels is still a challenge for the analytical science. Applying proper analytical technique, performed with instrumentation designed specifically for ionic and highly polar chemicals is the key.  Separated in their native ionic form on a new, designed-for-purpose ion exchange column Dionex IonPac CS21, polar pesticides and related highly polar compounds can be reliably quantified by tandem mass spectrometry without a need for derivatization.

Extracted by Quick Polar Pesticides Extraction (QuPPE) method, food matrices of oat cereals, baby food, flour and others were analyzed for Cationic Polar Pesticides, such as diquat, paraquat, chlormequat, and mepiquat by ion chromatography coupled to a tandem mass spectrometry (IC-MS/MS).

  • New IonPac CS21 column addresses the analytical challenge of the determination and quantitation of Cationic Highly Polar Pesticides in foods
  • New stationary phase solves the challenge of the critical pair Diquat – Paraquat separation and allows more cost-effective IC-MS/MS approach
  • Other challenging analytes from the classes of alkylamines, polyamines, and quaternary bases can be analyzed in power plant application areas

Alex Semyonov, PhD
Product Manager
Thermo Fisher Scientific

Alex was born in the USSR (now Russia) and started to get interested in Chemistry at the age of eight. At the age of ten, he had his own home lab, which eventually filled three rooms and counted over 1,700 chemicals. Alex has worked as a research organic chemist and Assistant Professor of Physical Chemistry at the Saratov State University. He left Russia in 1998 and entered into his 2nd graduate school at the Liquid Crystal Institute in the U.S., wherefrom he received his Ph.D. in Chemical Physics. After he set up a Material Characterization Laboratory, he switched the tracks and travelled through the Northeast part of the United States as a Senior Sales Engineer for Thermo Fisher Scientific – selling scientific instruments for seven years. Then he switched the tracks again to become a mass spectrometry product manager. In his current position, he leads the product management of ion chromatography – mass spectrometry (IC-MS).
