System and method for calibration of volatile organic compound detecting instruments

A method for completing a calibration process for a gas detector comprising:

• providing the gas detector comprising a probe, wherein the probe comprises:
• a housing operable attach to a main body of the gas detector, and operable to hold a calibration tube during calibration of the gas detector;
• a cap operable to attach to the housing, and operable to fit over and cover the calibration tube;
• and
• one or more inlets, wherein when the calibration tube is inserted into the probe, the air flows through the calibration tube, and wherein the calibration tube comprises activated carbon filter (ACF) material pretreated with a sodium bromide (NaBr) solution;
• breaking a portion of the calibration tube to allow air flow through the calibration tube;
• inserting the calibration tube into the housing of the probe;
• attaching the cap of the probe onto the housing, wherein the cap covers the calibration tube;
• completing calibration of the gas detector while the calibration tube is inserted into the probe;
• removing the calibration tube from the probe;
• and
• receiving gas readings by the gas detector.
