Gas Sampling - Manual 

Gases in most stacks or ducts often are comprised of small amounts of volatile, potentially toxic compounds in addition to major gas components such as nitrogen, oxygen, and carbon dioxide. At parts per million levels, most compounds with boiling points below that of water exist in a vapor state. Because gases generally are considered to be well mixed, sampling for constituents in the vapor phase usually is done through a simple probe from a single point of average gas velocity in the stack. 

Method 3            Gas Analysis for the Determination of Dry Molecular Weight

Method 3B         Gas Analysis for the Determination of Emissions Rate Correction Factor of Excess Air

Method 4            Determination of Moisture in Stack Gases

Method 6            Determination of Sulfur Dioxide Emissions from Stationary Sources

Method 7            Determination of Nitrogen Oxide Emissions from Stationary Sources

Method 18          Integrated Bag Sampling for Organic Compounds

Method 26          Determination of Hydrogen Halide and Halogen Emissions

Method 0031     Volatile Organic Compounds (SMVOC or SuperVOST)

Method 0040     Principle Organic Hazardous Constituents (POHCs) using Tedlar Bags

Method 6 Sampling Kit for VersaCase (SK-606) 

The Method 6 (SO2) Source Sampling Kit for VersaCase (SK-606) features the miniature VersaCase Method 6 measures sulfur dioxide (SO2) emissions from stationary sources. A gas sample is taken from the stack, and separated from the mist.
