Dissolved Gas Analyzer
The Dissolved Gas Analyzer GC System is designed to make dissolved gas analysis easier ands less expensive than other methods. No sample preparation is necessary prior to injection into the Dissolved Gas Analyzer GC; this helps to avoid contamination made possible by transferring the sample between various containers. The Dissolved Gas Analyzer GC may also be used online. For example, you could place the sample inlet tube directly into the ocean and analyze the dissolved gases in seawater.
In the Dissolved Gas Analyzer GC, the sample is injected by peristaltic pump through a unique gas extraction loop. The gas extraction loop consists of permeation tubing encapsulated in a trap-heated glass tube. The permeation tubing is plumbed to the sample inlet, the 10-port gas sampling valve and the waste/sample outlet.
