Is the Fourier Transform infrared method for emissions testing something that is included in most EMIT silencer/catalyst packages? Is this process industry leading or are there alternatives?

I would advise the following database if you are investigating unknown samples:
The spectral libraries we use are defined by our applications of emissions testing on natural gas engines, so they do not have detail of unknown starch samples.
Good day, i analysed a starch sample using FTIR and got a wavenumber of 4022 cm-1. I have checked all the spectra tables i can lay my hands on and i seem not to find a functional group that exhibits such wavenumber. Please i need help? My mail address is <firstname.lastname@example.org>
it is typically used as required by regulation, larger HP engines may be required to test with an FTIR annually and a lesser instrument may be used for quarterly testing
Interesting. FTIR is used at site during start up, is it used periodically after that to ensure elements do not need to be replaced or can a DPI be used?
The FTIR is an instrument used in our industry for testing exhaust gas emissions, the instrument is not included in the Catalyst /silencer packaged but rather used for a testing process once the unit is installed it is used to verify the performance of the Engine / Catalyst, there are other options for test instruments, but none as accurate, fast, or portable
