CHEMICAL DETECTION METHOD AND SYSTEM

A system and method for detecting an analyte of interest in a sample is provided. The method includes passing a set of ions obtained from the sample through an ion mobility spectrometer to filter out ions that are not ions of interest and to generate an ion mobility spectrum. A mass spectrum of at l...

Summary:A system and method for detecting an analyte of interest in a sample is provided. The method includes passing a set of ions obtained from the sample through an ion mobility spectrometer to filter out ions that are not ions of interest and to generate an ion mobility spectrum. A mass spectrum of at least some of the ions is generated using a mass spectrometer. The method also includes determining that the analyte of interest is in the sample when peaks of interest are found in one or more of the ion mobility spectrum and the mass spectrum, and the peaks of interest follow a predetermined pattern of peaks associated with the analyte of interest or are confirmed by ion mobility spectrometry.
