The present disclosure is directed to methods and systems for calibration, calibration verification, and sensitivity checks for a detector. The methods and systems include calibrating a detector by releasing at least one calibrant from at least one calibrant chamber in flow communication with the detector. The systems and methods further include verifying the calibration by releasing at least one verification substance from at least one verification chamber in flow communication with the detector. The systems and methods further include checking a sensitivity of the detector by releasing at least one sensitivity substance from at least one sensitivity chamber in flow communication with the detector.

Systems and methods for calibration, verification, and sensitivity checks for detectors

A detection system assembly is provided. The detection system assembly includes a detector system including a housing having a sample port configured to receive a sample of an unknown substance, a detector assembly in flow communication with the sample port, and a pump in flow communication with the detector assembly. The detection system assembly further includes a dryer cartridge removably coupled to an outer surface of the housing of the detector system. The dryer cartridge is in flow communication with the pump and the detector assembly.

Embodiments of the invention provide novel, industrially applicable, and non-obvious apparatus and methods for automatically, routinely, and accurately calibrating a trace detection portal. Embodiments of the apparatus include a calibrant container; a substance (or substances) uniquely identifiable by a trace detection portal as a calibrant; unique placement of the calibrant container's outlet relative to a substance collection port of a sample collection chamber; and/or computer executable instructions that, when executed by a computer processor, cause a consistent release of a measured amount of calibrant into the sample collection chamber upon command and/or at pre-determined time intervals.
