Refinery Gas Analyzer - RGA-3

The RGA-3 refinery gas GC is a fully functional refinery gas analyzer. The unit provides linear response for hydrogen concentrations from 0.02 - 100%. Hydrogen sulfide is analyzed with no difficulty. Water from wet samples is tolerated and causes no problems.

Liquefied samples use CIC's optional vaporizer (integrally mounted on the GC) with excellent results. A heated transfer line from the vaporizer assures gas phase injection of liquefied samples. This means the same sample injection valve used for gas phase injections is used for liquid samples, therefore a separate and easily plugged liquid sampling valve is not required.

In many older refinery gas GC systems, all heavies are backflushed as one peak. Therefore accurate response factors for heavies are very difficult to assign using these systems. In some cases the backflushed peak includes water and it goes to a TCD! With CIC's new refinery gas GC, heavy components are grouped and sent to the FID.

Most of the current refinery gas GC's do not resolve all of the chromatographic peaks of interest in a typical refinery gas or condensed liquid sample. The RGA-3 system completely resolves all of the peaks generally seen in most refinery gas and condensed liquid samples. This system can also be used to perform analyses on C2, C3 and C4 hydrocarbon or olefin samples, as well as natural gas samples.

Compare the chromatogram above to those from other refinery gas analyzers and then compare the prices. We believe this will put one of our new RGA-3 refinery gas GC's in your laboratory soon.
