Abstract:
FTIR is an excellent technique for quantifying trace analytes in various samples such as plant air, bulk gases, and process gases. A limitation of FTIR is that there is often too much interference from the sample matrix or other sample analytes present that the target trace analytes cannot be accurately quantified. Software for FTIR can allowsthe user to adjust the quant regions of any analyte in the FTIR spectra. In some cases. the software also allows the user to select which areas of the quant region will be included in the quantification based on the interference with the target analyte. This process is known as “picket fencing” and is a very useful tool for accurately quantifying target, and/or, trace analytes. The presentation will cover these processes, as well as their benefits and limitations, with the software platform.
