Abstract
A mass spectrometry system for screening a sample for one or more analytes includes a pre-mass spectrometry screening apparatus configured to pre-screen an ionized sample to generate output correlated to the composition of the sample, and a mass spectrometer. A sample gate is opened to allow flow of at least a portion of the ionized sample to the mass spectrometer and closed to prevent flow of the ionized sample to the mass spectrometer. A processing system compares results of the pre-mass spectrometry screening to an analyte database, wherein correlation of the results to an analyte within the analyte database comprises a preliminary positive identification. When the processing system determines that a preliminary positive identification is made, it causes the gate to open for a period of time. However, when the processing system determines that a preliminary positive identification is not made, it causes the gate to remain closed.
