ChemProX detection modes are essencially a set of rules and data to which chemical measurement results are compared with. If there is a match, it triggers an alarm. The detection modes are divided between CWAs and TICs in order to avoid false alarms: if both chemical types were gathered in one list, it could lead to an unsatisfactory number of false alarms.


Chemical detection specialists Teemu Partanen Mika Saarinen explain why ChemProX detection modes are divided into TIC detection and CWA detection to support the use in first response or in military situations.

TIC Detection Mode

  • TIC Detection: Detection mode that includes broad list of TICs. To be used as primary detection mode in situations of potential toxic threat.
  • TIC Classification: Detection mode with classification of toxic threats.
  • TIC Confirmation: Detection mode with identification of selected toxic chemicals.

CWA Detection Mode

  • CWA Standard: Detection mode for low threat-level scenarios, i.e. event security, where CWAs are only expected to be present in abnormal circumstances.
  • CWA Sensitive: Detection mode for heightened threat-level scenarios. Primary CWA sensitivity for military or first responders.
  • CWA High Sensitive: Detection mode for high threat-level scenarios. Suitable for example trace detection or personnel screening in situations where CWA attack has occurred.
