CompactGC for Gasodor S-Free measurement
The gas chromatographic method with CompactGC and
enrichment unit ensures that Gasodor S-Free™ is separated from all other
natural gas components before the concentration is determined in the
detector. There is therefore no cross-sensitivity to other natural gas
components. The system is capable of determining THT as well as Gasodor
S-Free. This also makes the CompactGC the ideal measuring instrument for
the new odorant Spotleak™ Z (88 % ethyl acrylate 12 % THT).
In
contrast to other measuring methods, both main components of Gasodor
S-Free (methyl acrylate and ethyl acrylate) are measured separately.
This makes it possible to check the correct ratio of both substances in
Gasodor S-Free.
The CompactGC is equipped with a cooled enrichment unit for the
Gasodor S-Free application. This unit is capable of collecting the
odorant in a defined manner. In a second step, the concentrated odorant
is injected onto the separation column of the gas chromatograph and
analyzed. The CompactGC is controlled by a software included in the
delivery. Commercially available GC columns are used as separation
columns. This is a clear advantage over the Micro GC, where the complete
module (injector, column and detector) is always replaced. The
CompactGC columns are easy to exchange and inexpensive.
