ChromLab software controls the functions of the NGC, including instrument control, method development, real-time monitoring, chromatogram comparison and peak analysis.
We have introduced a Robust Peak Analysis Algorithm (RPAA) which provide a mean for quantitative baseline estimation numerically from spectra which is a mixture of sharp features (high frequency peaks) and continuous, slowly varying (low frequency) baseline.
Functions of the system are controlled by proprietary ChromLab software that includes instrument control, method development, real-time monitoring, chromatogram comparison and peak analysis.

Peak analysis can be performed using the peak fitting module, which is included.
We therefore established standard PCR-restriction fragment length polymorphism (RFLP) methods for the 12 polymorphisms listed above and a melting peak analysis method using fluorescent probes (LightCycler assays) for the rapid detection of possibly functionally important EDN1 polymorphisms [except for +138/ex1ins/delA, for which a TaqMan assay already exists in our laboratory (11)].

A peak analysis based upon a spectral library indicated that the peaks are most likely associated with benzothiazole functionality.
In addition, analysts should know how reliably they are employing a particular peak analysis method from the uncertainties associated with operator choices such as the type of background function used in their fits.
