NGA - Natural Gas Analysis Extension

Extension for Natural Gas and Liquefied Petroleum Gas Data Processing.

NGA Extension is a software module for natural gas and liquefied petroleum gas data processing. You no longer need an external tool for gas properties calculations since Clarity contains the complete workflow of data acquisition, peak calibration, reporting, and gas properties calculations based on supported norms. It is possible to perform summary calculations of gas properties from multiple signals and chromatograms.
