Section 1912: Toxic Organic Compounds in Ambient Air - EPA Method T014

We have recently (September 2003) purchased an Agilent 6890/5973 GC with mass spectral capabilities and are in the process of developing a new analytical method for air toxics applications. The new method will be similar to the old one in that it will use cryogenic trapping and focusing to sample the canisters of ambient air. The difference will be in the new capability to tentatively identify unknown compounds using the MSD.

In addition we will be developing the capability to analyze for some semivolatile compounds using an oven to warm the canisters in conjunction with the same analytical system.

The report limits below are anticipated to remain the same for the new method.
