WebOct 28, 2015 · The assessment for the evaluation of the capabilities of GC-MS(/MS) and LC-MS/MS for the determination of pesticides carried out by Alder et al. and Carmona et al. showed that a wider scope and better sensitivity is achieved by LC-MS. The wide scope of pesticides covered and simple sample preparation is the key reason why liquid … WebAnalyzing vaccines, recombinant proteins, fusion proteins, and/or mRNA vaccine candidates using : LC-MS, GC-MS, Electrophoretic techniques such as SDS-PAGE, CD, DLS, DSC, FTIR and Karl Fisher ... WebIn GC-MS it is mostly the chromatography part that causes the difficulties. The growing importance of LC-MS/MS is also reflected by the fact that the vast majority of recent pesticide-residue-related publications deal with this technique rather that with GC.
