APPARATUS AND METHOD FOR RELATIVE OR QUANTITATIVE COMPARISON OF MULTIPLE SAMPLES

摘要

An apparatus (10) and method are provided for conducting comparative, relative or quantitative analysis of multiple samples. The apparatus (10) includes a plurality of ion sources (121, 12N) and a capillary structure (141, 14N, 181, 18N, 20) configured to direct ions to a mass analysis instrument (30). The apparatus and method may include post-ionization, gas-phase combination of one or more of the samples with one or more reagents (161, 16N) for quantitative or relative comparison of one or more of the samples.
