Abstract: A system and method for establishing the cleanliness of a device by performing a test is described. The system includes an ion mobility spectrometer to measure target signal strengths, and to measure n2?1 test signal strengths of a device sample. The system also includes a statistics module to obtain a value of a statistical confidence-level parameter that is associated with a particular confidence level, and a pass range module to obtain a pass range of signal strengths from the value of the statistical confidence-level parameter and the n1 target signal strengths. The system also includes an averaging module to obtain an average test signal strength from the n2 test signal strengths, and a results module to determine that the device passes the test, indicating that the device is significantly clean to within the particular confidence level, if the average test signal strength lies in the pass range.

Abstract: A system and method for introducing and analyzing a sample containing an analyte using an ion mobility spectrometer are described. The system includes a temperature module for adjusting the temperature of the sample according to temperature instructions received, and a split ratio module for adjusting the split ratio according to split ratio instructions received. An ion mobility analyzer determines an ion mobility of the analyte. The ion mobility analyzer collects a plasmagram of the analyte to identify and quantitate the analyte.
