Over the past years, Pascal Kooij worked as an HLO analyst at the Materials Research and Chemical Analysis Laboratory (LMC). He mainly focuses on organic analyses. For this, he developed methods for things including medication analysis with the LC-MS/MS and the wide screening HILIC method with the QToF. He also worked with GC-MS, ICP-MS and Pyrolyse-GC-MS. He expanded his expertise on these techniques through years of experience and equipment trouble shooting.
