New Jersey ATM 1

Isokinetic.
Heated out of stack filter (M5).
"Condensible" particulates pass through the filter and condense in impingers. Can readily be combined with a CPM Method.
Tester may adjust out-of-stack filter temperature to suit source specific conditions.

Particulate Matter (PM) -- those substances retained in the sampling nozzle/probe and on a heated filter after the removal of uncombined water.

A minimum sample catch of 50 mg is targeted to calculate the minimum sample times
- An absolute minimum of 3 mg catch is required;
- Any expected catch of less than 50 mg will require the use of EPA Alternative Method 005 to process the samples.
During sampling a filter is maintained at a specified temperature (248oF + 25oF)
Do not use silicone grease - it can be soluble in the probe rinse and can bias the PM value high.
Run the train isokinetically.
Stainless steel nozzles should be used with great care, port scrapings can bias results high.

Acetone 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 rinses separate, ship other samples normally, and the acetone as hazardous.
Be sure to include a chain of custody for each shipping container.

This method is the state of New Jersey version of Method 5 - Promulgated in the mid 70's.
The Front Half acetone rinse is to be baked after evaporation - prior to weighing.
