  • Patent number: 5402668
    Abstract: The invention is an apparatus and method for preparing volatiles collected from a sample for gas chromatographic analysis. Volatiles are collected from the sample in a volatile trap, such as a porous polymer trap. The volatile trap is then connected to a transfer line. The trap is heated to thermally desorb the volatiles, and an inert gas, such as helium, flows through the heated trap to transport volatiles through the transfer line into a capillary column located in a gas chromatograph oven. Inside of the oven, a portion of the capillary column is cooled with a cooling fluid such as liquid nitrogen to form a cold trap. When the cold trap is cooled, the desorbed volatiles are trapped in the cold trap. Then the cold trap is heated to allow the volatiles to be released and the volatiles are carried to the remainder of the capillary column for chromatographic analysis by an inert carrier gas.

  • Patent number: 5369983
    Abstract: A detection medium and method for use in detecting gross and fine leaks in a hermetically sealed package. In a preferred embodiment, the detection medium includes a detectable perfluorinated gas dissolved in a detectable perfluorinated liquid. The package is placed in a bombing chamber and then exposed to the detection medium under pressure introduce the detectable liquid and dissolved, detectable gas into the package through any gross leak openings and to introduce the detectable gas and some detectable liquid vapor into the package through any fine leak openings. The package is then removed from the detection medium and air dried to evaporate any detection medium attached to an exterior surface of the package. The package is placed in a test chamber which collects detectable gas and vapor of the detectable liquid escaping through the gross and fine leak openings. A measurement instrument detects whether a component of the detection medium has escaped from the sealed package as an indication of a leak.

  • Patent number: 5354347
    Abstract: A vacuum system which uses water as a filtration medium to effectively capture dirt and dust particles. The vacuum system uses a canister or tank, which can be placed on a wheeled mobile frame for mobility. Within the tank, a removeable insert includes a number of equally spaced annular plates with a first of the annular plates fitting snugly against the outside wall of the tank and the next plate fitting snugly against the outside wall of a central cylindrical column. The plates then continue to alternate from outside wall of the tank to the outside wall of the column to form alternating gaps and, thus, a serpentine airflow path. The bottom portion of the tank is filled with a quantity of water sufficient to cover the bottom of an air intake port. A blower draws air, along with accompanying debris, from the intake port through the water.
