1. A method of quantitating analyte in a process gas stream, said method comprising:

  • providing a gas sensor system having a plurality of sensor cells, each sensor cell containing a plurality of semiconducting metal oxide gas sensors;

    calibrating each one of said sensor cells;

    baselining each one of said sensor cells;

    causing a process gas to flow through each one of said sensor cells for a respective time interval;

    processing sensor outputs of each one of said sensor cells over its respective time interval to determine the amount of analyte in said process gas in each time interval; and

    adding the analyte amounts determined for each time interval to determine a total analyte quantity.
