We have a high concentration quantitative gas library for short path gas cells.  This library is a good reference library.  In most cases, each compound has a range in concentrations.  These compounds have been run at 2 cm-1 resolution with triangular apodization.  The spectra was run from well controlled standards. 

Note: Each spectrum in the the library also comes with the raw unprocessed interferogram.  One has the option to use whatever zero fill and apodization function and then transform the interferogram to what ever resolution desired.  This raw format of the data allows one to use FCM (see FCM pages at FTIR.com) to create a synthetic reference (artificial reference) as the background file.  This powerful feature allows one to do continuous flow monitoring without the need to collect a background zero gas reference spectrum. 

There are other library spectra available.  In general the spectra is at a concentration at 1 ppm-meters at 1 and 2 wave number resolution.   We will provide a list of those compounds on request.
