Abstract Body: Utilizing a 30M resistively heated capillary column on a GC configured with a PID/FID can improve both the time of the analysis and the separation of VOCs. The use of a second detector (FID) provides confirmation of peak identity.
We will employ resistively heated columns to reduce the total analysis times by 50-60% and use the PID/FID response ratios to enhance identification of components of interest. These ratios have been used previously (1) to identify the molecular structure of hydrocarbons.
A PID Analyzers compact GC(<20#) with an external laptop will be used for the analysis that incorporates the resistively heated column technology. As a result of the superior heat transfer of the electroplated nickel, we are able to rapidly and efficiently heat and achieve excellent resolution on long capillary columns. A mini-FID was designed that will easily attach to the outlet of the PID taking a single detector port and providing improved identification of components.
