Calibrating canines - a universal detector calibrant for detection dogs

In this study, Getxent tubes were impregnated with 1-bromooctane, a Universal Detection Calibrant (UDC). The study shows that:

• Getxent tubes release 1-bromooctane (UDC)
• "The Getxent tube has the added benefit of providing an adjustable level of odor, i.e., the longer the tube is co-incubated with odorants to “load” the tube, the emission rate of those odorants increases."
• The 1-bromooctane (UDC) "collected from the headspace of the tubes increased linearly with increasing exposure time"

It thus concludes that the Getxent tubes are a highly promising tool to "lower detection threshold by reducing the abundance of odor systematically."
