Trace moisture quantitation is crucial in medical, civilian and military applications. Current aquametry technologies are limited by the sample volume, reactivity, or interferences, and/or instrument size, weight, power, cost, and complexity. We report for the first time on the use of a pulsed discharge helium ionization detector (PDHID-D2) (∼196 cm(3)) for the sensitive (limit of detection, 0.

- * A new device called the mesoscale pulsed discharge helium ionization detector (micro-PDHID) was developed, which is significantly smaller than commercial versions but maintains similar performance metrics.
- * This device was able to detect human-emitted compounds with only a slight decrease in sensitivity and has proven to be durable, functioning reliably for 9 months without any issues.
