EPA Method 204a - Volatile Organic Compounds in Liquid Input Stream
- At least 3 sampling runs
- Runs should be between 3 to 8 hours long
- Each run should be covering one complete production cycle.
- Unless product cycle is longer than 8 hours
- The amount of VOC containing liquid introduced to a process is determined as the weight difference of the feed material before and after each sampling run. The VOC content of the liquid input material is determined by volatilizing a small aliquot of the material and analyzing the volatile material using a flame ionization analyzer (FIA). A sample of each VOC containing liquid is analyzed with a FIA to determine the volatiles content.
- Total VOC
- FIA Response Factor to each feed stream input
- Amount of VOC containing liquid in the process determined using feed material before and after each run.
- VOC content determined by analyzing an aliquot using a flame ionization detector (FID).
- Samples may qualify to be shipped as a hazardous material. Please call for IATA codes if you need them.
- The most useful data are determining the response factor of a given feed stream on an FIA (Total Hydrocarbon Analyzer).
- Direct conversion factors, from propane to feed stream, can be determined
- Units = lb Feed Stream per lb Propane (or Methane)
