We conduct Stack Emission Test by using proper stack samplers. Samples are collected from the stack sampling point by extracting the flue gas by the sampler. Appropriate extraction thimbles and absorbing reagents are used to collect the samples. The samples are then analyzed in the laboratory for the required parameters. Automatic Flue gas analyzers are also used to test the emitted gas for gaseous pollutants. We adopt a very scientific and systematic approach while rendering Stack Emission Test Services. The absolute accuracy of our results reflects our efforts.
