SAMPLING PARAMETERS FOR SULFATE MEASUREMENT AND CHARACTERIZATION

Evaluations of critical sampling parameters have been performed for primary sulfate measurement and characterization with a selective condensation method. It was found that filtration temperature and sampling flow rate were the critical parameters and that sampling conducted using variations of the parameters would result in incomparable data. It was also found that a viable temperature controlled H2SO4 collection device could replace the Goksoyr-Ross coil and alleviate H2SO4 recovery and pressure drop problems which are common to the methodology. © 1979, American Chemical Society.
