The standalone comprehensive software package OPUS GA (OPUS Gas Analysis) allows to identify and quantify gas compounds in a continuous and fully automated manner, without the need for gas calibrations or expert knowledge. Major features of OPUS GA are:
With the available quantitative gas library, OPUS GA allows for the identification and quantification of more than 300 gas compounds without the need for calibration. Beyond that, OPUS GA provides an interface to measure individual reference spectra and add these to the existing library. At any time, existing measurements can be analyzed based on an updated library of reference spectra without the need to rerun the measurement. For the expert user, the measured gas spectra can be investigated in detail within OPUS GA.
The quantification of gas compounds is based on a unique non-linear fitting algorithm which fits the reference spectrum to the measurement. The algorithm allows for an accurate detection and quantification of compounds even in the presence of interfering gas compounds, which are included in the fitting procedure. The influence of varying gas temperatures and pressures is considered by the analysis routine.
OPUS GA allows the user to simulate spectra based on high-resolution reference spectra of any gas compound existing in the spectral library. The spectra are simulated under real environmental conditions, like temperature, pressure, and the spectral resolution of the spectrometer. The simulation module facilitates to identify unknown compounds in a gas mixture.
OPUS GA establishes an easy-to-use graphical user interface to control MATRIX-MG and OMEGA 5 gas analyzers. The user can conduct a fast, continuous and fully automated identification and quantification of gas compositions with minimum training effort. Expert knowledge in spectroscopy is not required.
