Abstract
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.
