Mass spectrometry is the standard laboratory technology for detecting, differentiating and identifying trace levels of chemical compounds in complex chemical environments. Mass spectrometers are uniquely sensitive and accurate. They extract chemical signatures from test samples much more quickly and accurately than is possible with alternative technologies. They eliminate false positives. However, most conventionally designed units are too big and cumbersome to be deployed outside of a laboratory.

Our units provide unparalleled selectivity through multidimensional mass analysis, MS/MS or MSn. MS/MS provides both a first-stage mass analysis to determine if a particular analyte of interest is present in a test sample, and, within milliseconds, a second-stage confirmation of the analyte's identity. Analysis this precise has never before been available in a person-portable unit for use in the field.
