Determination of impurities in gas phase VC
The purpose of determining impurities in gaseous VC (vinyl chloride) is a quality control measure to avoid contamination of VC and off-spec product batches.
Background
The on-line analyzer system uses gas chromatography for monitoring methylchloride – ethylchloride – butadiene – vinylacetylene – 1,1 EDC – 1,2 EDC
Typical measuring ranges
0 – 100 ppm methyl chloride
0 – 20 ppm butadiene
0 – 500 ppm vinylacetylene
0 – 100 ppm ethylchloride
0 – 20 ppm 1,1 EDC
0 – 100 ppm 1,2 EDC
