The ability to effectively screen passengers with minimal personal contact is critical. Ion mobility detectors used at many airports can be inaccurate and provide many false-positives and false-negatives. Advanced Imaging Technology (AIT) screening techniques are very useful for detecting concealed weapons and explosive devices located on passengers and/or in their belongings, however are unable to detect trace amounts of explosive residues.
The expression® Compact Mass Spectrometer (CMS) with an Atmospheric Solids Analysis Probe (ASAP®) is a high performance instrument with a small footprint that allows airports to better screen for explosive residues on passengers and their belongings.
The expression® CMS provides rapid and accurate detection with significantly reduced false-positives and false-negatives than ion mobility instruments.
