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 n≧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 ntarget signal strengths. The system also includes an averaging module to obtain an average test signal strength from the ntest 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.
