Gas Chromatograph

Designed to provide fast, effective, and precise measurement of non-condensing hydrocarbon species during well logging and carbon bed detection.

About

The Measuresoft Gas Chromatograph (GC) is the candidate of choice whenever accurate, reliable qualitative hydrocarbon species analysis is required. The GC has a lower detection limit of 10 ppm. The analyzer has an availability of analog and logic output capabilities.

The analyzer is based on a flame ionization detector (FID). During the combustion process, organic or hydrocarbon-based gases in the sample are ionized, then detected by the instrument and reported as a concentration in ppm.

The instrument is calibrated to ensure accuracy of +/- 5%, and is stable to within +/- 1% of full scale.

Applications

Designed to continuously monitor the total hydrocarbon content of non-condensing gases in a variety of applications, such as:

• Carbon bed breakthrough detection
• Well logging
• Quick and efficient C1-C5 analysis including i-C4/C5 and n-C4/C5
