Quantitative analysis of surface-derived samples using mass spectrometry

摘要

A substrate incorporating an internal standard facilitates quantitating analytesin a sample by surface-interrogating mass spectrometry techniques withoutwet chemistry sample preparation. The user disposes a sample to be analyzed ontothe surface of the pretreated substrate. Then the sample-bearing solid substrate,which incorporates an internal standard for each analyte to be quantitated,is ready for interrogation.
