Abstract
Vacutainers are used by the Bureau of Mines and the Mining Enforcement and Safety Adminstration (MESA) for sampling mine air and products of combustion. Tests were conducted on both 10-ml and 30-ml sizes to study shelf life stability during storage, pretreatment of stoppers, and handling of a wider range of compounds. A chamber was constructed to provide convenient, efficient evacuation of the vacutainers shortly prior to use. Fixed gases and c1-c5 hydrocarbons could be stored for 1 week or more after sampling. Where decreases occurred (co2 and c3-c5 hydrocarbons), they were predictable as a function of storage time. An unexplained phenomenon, slow accumulation of CO in evacuated vacutainers, occurred after a few weeks of storage. The levels were low and time dependent. Attempts to eliminate this behavior by pretreating the stoppers were unsuccessful.
