1. A gas monitoring system including a TPIR detector, operatively arranged for a sensing operation comprising any of:

  • (a) sensing of a multicomponent gas to determine a concentration of a component therein other than a component detectible by the TPIR detector;

    (b) sensing of gas in a cell having a multiplicity of zones therein defined using fiber optic cables to provide a multiplicity of gas sensing paths within the cell;

    (c) sensing with a modulated infrared radiation source switched in on/off cycles;

    (d) sensing of a fluid sampled from a supply package to verify identity of fluid contained within said supply package;

    (e) sensing of effluent from an environment after treatment to remove contaminants therefrom; and

    (f) sensing of effluent from a cold trap system to determine when a cold trap has been loaded and requires regeneration.
