The S-LAB plate handler from Peak Analysis
& Automation (PAA) is easy to use, compact, and offers the same reliability as a robotic arm.

The stability and reproducibility of the analytical results of differential analysis were confirmed by both individual peak analysis
using the Qualbrowser program and another dataset derived from samples prepared on a different day as independent experiments.

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
. The software's instrument controls are designed around a fluidics scheme interface that is customizable.
A pre-configured menu system allows users to select various settings including standards, test levels, test methods, modulation settings, leveling methods, limit lines, peak analysis
and failure analysis.
Preliminary results using Raman spectroscopy revealed a significant peak analysis
at a Raman shift of approximately 3000 cm-1.
Data analysis tools include statistics, signal processing, curve fitting, and peak analysis
. Peak analysis
can be performed using the peak fitting module, which is included.
Figure 2 shows a case where two gates per segment are selected for peak analysis
. Up to 64 gates per segment may be defined.
