Claim:
1. A system for identifying and quantifying metal species, the system comprising: a) a collection interface unit for collecting a sample and concentrating an analyte, wherein the collection interface unit comprises a plurality of different interfaces, each interface including a surface onto which one analyte from one sample is collected, wherein the plurality of interfaces are configured to collect both gas-phase analytes and particulate-phase analytes; b) a soft ionization mass spectrometer which is configured to identify and quantify a content of each analyte in terms of metal species contained therein; and c) a flow tube for connecting an outlet of the collection interface unit to an inlet of the soft ionization mass spectrometer; wherein each interface defines a distinct sample flow path to the inlet of the soft ionization mass spectrometer; a plurality of flow control units associated with the sample flow paths and controllable such that only one sample is analyzed by the soft ionization mass spectrometer.
