Re: Mass spectrometry A level « Reply #3 on: December 25, 2024, 08:58:37 AM » Hi! if your asking why the lighter ions travel faster towards the detector then: (if not just ignore what I'm saying)In mass spec all the ions are accelerated to the same kinetic energy using an...
In general, a mass spectrometry is an analytical technique that involves the ionization of a chemical species followed by the sorting of the ions based on their mass to charge ratio. From: General Chemistry for Engineers, 2018 About this pageSet alert ...
Mass spec quantitation—General Q.What is the difference between Relative and Absolute Quantitation? Which type of quantitation is used for proteomic samples? A.Relative quantitation compares the amount of an analyte in different samples. Absolute quantitation measur...

Neither of these c-LPHs exactly matches a previously reported sequence.83 Based on the tandem mass spec- trum shown plus additional enzymatic and Edman deg- radation data (not shown), we identiÐed the major variant (RMM 4388) as [His-12]-c-LPH. The tandem mass spectrum of the ...
