THE VAPORATOR, A DEVICE FOR MEASURING THE VAPOR SOURCE STRENGTH OF CW-CONTAMINATED SURFACES PART Ⅰ – BACKGROUND AND PROTOTYPE

摘要

The Vaporator is a small, lightweight device to be used with the Navy M-15 Chemical Agent Detector Kit for measuring the vapor source strength of CW-contaminated surfaces. The device is essentially a two-compartment metal cup, one part of which contains an activated-charcoal air filter. Using the rubber bulb of the M-15 kit, air is drawn at a fixed rate and in the desired volume through the charcoal and over a surface suspected of being contaminated. In this way, only puri-fied air passes over the sample surface, and the test blank is zero. High sensitivity results from continuous sweeping of the sample surface with a current of air.
