The most common and widely used method (world over) is extractive sample method or Grab sampling technique. Grab sampling technique is also often treated as the reference standard method. Grab Sampling technique is not restricted to a specific pollutant. The same system with different reagents may be used for a variety of pollutants and over different ranges of concentration. This Stack Sampler VSS1 is one such Grab Sampler which can monitor Particulate Matter (PM) and any watersoluble gaseous pollutants like SO, , NO., HF, Cl, , H, S, NH, etc., in industrial emissions from Stationary source I Chimney and Vent.
PORTABILITY FOR ROUTINE SAMPLING Only repeat and frequent monitoring can give a true insight into the emission characteristics. It is thus more important to have a simpler and handy device,which can be used more often with ease and convenience, rather than a bulky and cumbersome system. At times transportation efforts become more hectic & expensive than the actual monitoring exercise. Based on our experience and valuable feedback obtained from our large group of valuable customers, regulatory authorities, consultants, and R&D Centers, need for improved and Handy instrument has been felt.
The Stack Sampler VSS1 has been designed to overcome such problems. The operating principle is simple. The Particulate Matter is collected over a filtration thimble. It entrap and absorbs various gaseous pollutants in suitable reagents, which are analyzed subsequently by simple Wet Chemistry methods to determine the concentration of specific pollutants.
