Patent abstract

A point-of-care mass spectrometer system has a sampling system, an ionization component structured to receive a sample for analysis from the sampling system, a mass analyzer structured to receive a source of ions for analysis from the ionization component, and a detector structured to detect ions from the mass analyzer and to generate an output signal. The sampling system selects a subset of peptides from a sample by immunopurification of multiple histocompatability complexes and concentrates the subset of peptides to provide the sample to the ionization component.
