Analysis of liquefied and compressed gases
Standard-compliant to ASTM D 2163 and D 2598
Product description
The MobilGC is a gas-phase chromatograph and easy to use. Measurement of gas composition according to ASTM standards D 2163 (LPG analysis) and D 2598 (evaluation method) is possible with combination of the Sampling Box.
The rugged case and the internal gas supply allow the LPG analysis on-site at the measurement points. The measurement sensitivity fulfills the requirements of the ASTM standards: 0.1 to 100 % of clean gas components.
For sample preparation the Sampling Box has to be connected with the gas bottle or sampling line of the liquefied gas and with a sampling bag. 5 ml liquefied gas is taken and transferred to the sampling bag for expansion. In this way you can also make gas mixtures by addition of further components, e. g. for calibration.
For analysis the sampling bag has to be connected with the MobilGC. A heated column separates the gas sample. With the comfortable software of MobilGC an easy chromatogram evaluation according to standards is possible. The integrated expert evaluation system shows the result as concentration and additionally as total MON number or as MON value separately for each component.
