Workplace exposure monitoring is another excellent application for FTIR spectrometry because by definition the chemicals that need monitoring are nearly always known. With this knowledge, an FTIR analyzer can be set up to monitor all the compounds that might be present in any type of production facility. If just one compound is left out, a false positive or negative result could be reported due to the potential spectral frequency interference of any gas with another. Therefore, it is very important to have an analysis method that includes all gases that have any potential to be observed on a particular site.

A key feature of FTIR analyzers is that most are now manufactured with large quantitative chemical databases that can be monitored simultaneously, so no calibration work is necessary to monitor for many chemicals. 
 
Also, since most production facilities try to limit the number of airborne chemicals on any specific site, lower resolution instruments or settings can be effectively used since high levels of water (the largest interference in most IR spectra) are not normally present. A lower resolution instrument can provide detection limits down to the tens of ppb for numerous compounds.
 
The FTIR Specialists at Prism have been performing ambient air monitoring since 1987, and were actively involved in the development of the most sensitive ambient air FTIR analyzer ever offered for sale. We can answer any questions you may have concerning specific atmospheric gases and the capabilities of an FTIR analyzer to monitor for those gases at any concentration level.

We can assist you with your fence line application and help ensure accurate measurements.
