ABSTRACT
     The accurate measurement of the total nonmethane volatile
organic carbon emissions from stationary sources is critical to
characterizing of many industrial processes and for regulating
according to the Clean Air Act.  Current methods are difficult to
use and the ability to do performance audits has been marginal,
especially at low concentrations (50 parts per million of carbon,
ppmc).  One of the key elements for an ideal measurement technique
would be a detector that responds to all classes of organic
compounds equally, based on the number of carbon atoms present.  A
commercially available catalytic flame ionization detector (CFID)
has shown promise in this area.  Laboratory studies with a CFID
were performed to determine the response of compounds with various
functional groups.  These classes included brominated, chlorinated,
nitrogenated, oxygenated, aromatic, and non-aromatic compounds. 
The response of each compound is compared to the response of an
alkane with the same number of carbon atoms.  This paper will
discuss this phase of the experimental work.  Future work with this
detector will incorporate an approach for sampling, sample
recovery, and field tests for comparison to the EPA Method 25.
