1. A gas sampling filter for use in a system for measurement of vapor-phase mercury in a flue gas stream, said filter comprising:

  • a filter element to separate particulates from the gas being sampled;

    a heater heating the filter element;

    a first temperature sensor measuring the temperature of the flue gas stream;

    a second temperature sensor measuring the temperature of the filter element; and

    a controller regulating the heater to minimize the difference between the temperature of the flue gas stream measured by the first temperature sensor and the temperature of the filter element measured by the second temperature sensor.
