Thermal conductivity detector assembly

Abstract

Abstract A PAIR OF SEPARATE THERMAL CONDUCTIVITY DETECTOR CELLS, EACH CONTAINING TWO DETECTING ELEMENTS, ARE CLAMPED BETWEEN TWO MATING HOUSING HALVES WHICH PROVIDE A LARGE HEAT SINK. EACH OF THE DETECTOR CELLS INCLUDE A SINGLE PASSAGE IN A HOUSING SYMMETRICALLY DISPOSED ABOUT THE AXIS OF THE PASSAGE OF FACILITATE MATCHING LIKE CELLS FOR USE IN THE DETECTOR ASSEMBLY. THE DETECTING ELEMENTS ARE COAXIALLY DISPOSED AT BOTH ENDS OF EACH CELL. GAS IS INTRODUCED AT THE CENTRAL PORTION OF EACH PASSAGE AND PERMITTING A SPLIT AND FLOW OVER THE RESPECTIVE DETECTING ELEMENTS AND EXIT AT THE RESPECTIVE ENDS OF THE PASSAGE. CONDUITS FOR CONDUCTING THE GAS TO AND FROM THE RESPECTIVE DETECTOR CELLS PASS THROUGH AN OPEN SPACE BETWEEN THE TWO MATING HOUSING HALVES WHICH AIDS IN REDUCING DELETERIOUS THERMAL EFFECTS AND FACILITATES CONSTRUCTION OF THE ASSEMBLY.
