QUANTITATIVE ANALYSIS OF SURFACE-DERIVED SAMPLES USING MASS SPECTROMETRY

摘要

A substrate incorporating an internal standard facilitates quantitating analytes in a sample by surface-interrogating mass spectrometry techniques without wet chemistry sample preparation. The user disposes a sample to be analyzed onto the 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.
