Gas Analysis Software for Quantification of Gas Mixtures
SPGASTM is a sophisticated gas analysis software that performs the quantification or estimation of the concentrations of known gases in a gas mixture. The SPGAS quantification analysis engine (chemometric package) is based upon a modified version of the Classical Least Square (CLS) multivariate calibration method which is called Weighted Multi-Band CLS. This method, instead of using the entire infrared absorption spectrum of a molecule, divides the absorption spectrum of a molecule into different regions called bands, and then performs a quantification analysis on each band; the goodness of concentration estimation for each individual band is weighted and a weighted average concentration is calculated for the entire set of bands.
The following list represents the key features offered by QMax and the SPGAS Quantification analysis engine:
- Weighted Multi-band Classical Least Squares concentration analysis
- Deviations from Beer’s Law and non-linear corrections per band
- On screen visualization per band of residual spectrum, weighted analysis, and concentration estimation.
- Save residual spectrum
- Each individual Quantification Set provides:
- Serialization
- Data Password Protection
- CRC file modification detection
- Inclusion of reference spectral into the quantification analysis.
Every PC system on the market currently has sufficient power to run any of the SPGAS applications. The following list represents the absolute minimum requirements for QMax to run properly.
- Processor: Intel or AMD Processor, 166 Mhz (Minimum)
- Operating System: Windows 98, Windows Me, Windows NT 4.0 or Windows 2000
- Memory: 64MB (Minimum)
- Disk Space: 20MB (Minimum free space)
- Screen Resolution: 800x600 with 256 colors (Minimum)
