Sulphuric Acid Sampling Equipment

New NIOSH Methods for Sampling and Analysis of Airborne Inorganic Acids

The revised NIOSH Method 7906 is applicable to the determination of masses of 0.005 mg to > 1 mg of particulate fluorides per sample and 0.0125 mg to > 1 mg of HF per sample. The concentration range of particulate fluorides and gaseous HF in air for which the measurement procedure is applicable is associated with the selected sampling protocol.

Sample Points. The sample points for determination of plant emissions (SO2 and acid mist) are generally located on the stack. The sample point must be located a minimum of 2 stack diameters from the top of the stack and a minimum of 8 stack diameters from the stack breach. These criteria ensure that the gas flow past the sample points is uniform.
