Method Overview

• Isokinetic
• Heated out of stack filter (M5).
• "Condensable" particulate matter passes through a filter and condenses in dry impingers.

Target Compounds

• Both Filterable and Condensable Particulate Matter are measured. The total of all fractions represents the Particulate Matter.

Performance Tips

• Filterable Particulate Matter
  • Do not use silicone grease - it will be soluble in the final train rinse and can bias the organic CPM value high.
  • Run the train isokinetically or pseudo-isokinetically if combined with M201, M201A or OTM 27
• Condensable Particulate Matter
  • CPM is collected in the Greenburg Smith impingers of the sampling train as described in this method.
  • The total of the aqueous and organic fractions represents the CPM.
  • IMPORTANT - ether is an extremely flammable solvent! It should only be worked with under a hood!
  • IMPORTANT - Many resin type DI systems do not produce water of a grade that meets the 0.001% criteria for blanks. Blank-test your water before testing. If purchasing H2O, DI/UF grade is recommended. The organic extract and the water are separately evaporated.

Shipping

• Acetone, ether, and chloroform must be shipped as a hazardous material. Please call for IATA codes if you need them.
• Samples may be shipped at ambient temperatures.
• It may prove more economical to keep acetone, ether or chloroform rinses separate, ship other samples normally, and the solvent rinses as hazardous.
• Be sure to include a chain of custody for each shipping container.

Applications

• A draft method - never officially promulgated.
• Some "older" facilities may have had this test method written into their permits.

Accreditation

• No, please contact us if you are interested!
