Liquid chromatography coupled to triple quadrupole tandem mass spectrometry (LC–MS–MS) in multiple reaction monitoring (MRM) mode is widely considered as the gold standard for pesticide analysis. In this article recent developments in LC–MS–MS technology to meet increasing regulatory demands and productivity targets in quality control and contract laboratories are explored.
This article provides some tips and tricks for monitoring sample recovery and peak area using GPC/SEC.
To understand how the HPLC system works, it can be useful to first identify the basic components of virtually every system. Armed with that information, envisioning the HPLC system as comprised of three different zones - each with unique characteristics and each with its own set of requirements - can offer further guidance.
