How a lcmsms works
WebIon suppression in LC-MS and LC-MS/MS refers to reduced detector response, or signal:noise as a manifested effect of competition for ionisation efficiency in the ionisation source, between the analyte(s) of interest and other endogenous or exogenous (e.g. plasticisers extracted from plastic tubes, mobile phase additives) species which have not … WebPart 2 examines the important role of mobile phase components, specifically the ionic modifiers. In this article, the LC-MS/ MS optimization for analysis of spice cannabinoids is demonstrated using a range of mobile phase additives for increased analyte response and selectivity. A four-pronged approach leveraging HPLC column selectivity ...
