Maximum absorbance algorithm for reconstruction of gas chromatograms from gas chromatography/infrared spectrometry data

Gas chromatography/Fourier transform infrared/mass spectrometry using a mass selective detector

“…This new maximum absorbance reconstruction algorithm (AMAX) gives equal or better sensitivity than the Gram-Schmidt reconstruction algorithm (15) for the samples used in this study. A detailed comparison of the maximum absorbance algorithm with both the Gram-Schmidt and integrated absorbance (or "chemigram") (16) algorithms suggests this may be a general observation (17).…”

Hyphenated Methods for Identification After Chromatographic Separation

“…Three techniques are commonly used for reconstructing the Chromatographie information from the absorbance data [105][106][107][108]. Three techniques are commonly used for reconstructing the Chromatographie information from the absorbance data [105][106][107][108].…”

Scan-to-scan nonreproducibility in GC/FTIR: An evaluation of several chromatogram calculation algorithms

“…The poor sensitivity of the IA method when used with relatively wide windows has been attributed to inclusion in those windows of baseline containing only noise [7]. It is useful to distinguish between "high frequency" noise (i.e., noise which varies rapidly from point to point across the spectrum) and "baseline wander" (noise which varies slowly across any given spectrum, but which can fluctuate rapidly from scan to scan).…”

“…A more sensitive "maximum absorbance" (MA) algorithm has been recently described [7]. In the MA algorithm, the largest absorbance value in the wave number range of interest (rather than the sum over that range) is reported as the Y-value of the chromatogram.…”
