Super toxic analytical glove box system

摘要

An Analytical Glove Box System has a sealed instrumentation enclosure, a glove box having an injection port coupled to the instrumentation and an air lock through which sample vials can be passed from outside into the glove box. A pump is provided for withdrawing gas from the glove box enclosure through a filter system so that the glove box is maintained at a negative pressure with respect to ambient. Toxic chemical samples can thus be safely handled by an operator and analyzed with sophisticated instrumentation without the risk of contamination. All effluent from the glove box is filtered before release to ambient, leakage from the glove box is further eliminated due to the negative pressure differential maintained, and the instruments are isolated from the potentially contaminated environment of the glove box. The system further provides the ability to conduct highly toxic chemical analysis in field locations since it is portable (including air transportable) and is easily decontaminated.
