ANALYTICAL CHEMISTRY
Small thermistor sensing elements go into the new gas chromatography cells made b y Victor Engineering. T h e elements, says the company, enable faster response, more accurate and sensitive thermal conductivity detection and analysis. M a d e of stainless steel, the small cell block houses a matched pair of V E C O thermistor reference elements located almost directly in the gas-flow path. One sensing thermistor is for gas under test, one for reference gas flow, with the gases flowing completely through the cell block. E a c h cell has a bridge network, and gas connections can be made with V 8 - i n c h pipe fittings. P - 8
