Gas Sampler

A mechanical alveolar gas sampler using the revolver principle capable of collecting six individual expired gas samples is described. The 0.91-kg sampler collects 19-ml samples in pre-evacuated aluminum ampoules equipped with spring-loaded valves from a sampling chamber equipped with two removable one-way valves. On depression of external handles, one of six ampoules located in a removable cartridge is aligned and advanced into the sampling chamber where its valve is opened and then closed. Releasing the handles removes the ampoule from the sampling chamber and automatically rotates the cartridge through 60 degrees to position a new ampoule in preparation for the next sampling sequence. A lock-out mechanism prevents reexposure of any of the ampoules after six samples have been taken. The performance of the sampler is described including its successful use in the field to collect alveolar gas samples on the summit of Mount Everest.
