  • Ventilation unit for a flame photometric detection device
    Patent number: 5052805
    Abstract: A ventilation unit for a flame photometric detector that utilizes a vent tube, which communicate with the combustion chamber of the detection device and a cap which fits onto the tube to form a tortuous light path, such that the escape of combustion products through the vent tube does not allow extraneous light to enter the combustion chamber, a series of threads and tabs on the tube and cap allow the cap to be threaded onto yet to fit loosely about the tube.

  • Continuous air monitoring apparatus and method
    Patent number: 5014541
    Abstract: A continuous air monitoring apparatus utilizes a solid sorbent preconcentrator to concentrate airborne sorbent compounds for gas chromatographic analysis. Direct connection between the preconcentrator and gas chromatographic column allows direct desorption of the compounds into the column with minimal dead space. Temperature control on the column allows sharp chromatographic peaks to be attained without cryogenic focussing.
