Method for reducing the frequency of acquiring background / reference spectra in FTIR or FTIR-ATR spectroscopy, and a portable measurement device embodying the same
In FTIR or FTIR-ATR spectroscopy, it features a method for reducing the frequency of acquiring a background spectrum. Such a method includes determining whether there is an existing reference spectrum available and obtaining a current reference scan before obtaining a sample scan if such a reference spectrum is available. The method also compares the current reference scan to an existing reference spectrum to determine if there are one or more mismatches between them, and if there are one or more mismatches, Determining whether one or more inconsistencies can be resolved. If one or more discrepancies are resolvable, resolve each discrepancy in a determined manner, then obtain a scan of the sample, and if the discrepancy is not resolvable, obtain a new reference sample and then sample To get a scan.
