Abstract:

Chemical processing plants around the world have complex streams that require complex analyses. Another challenge is obtaining real-time, high-quality data about the streams. It is important to the plant’s profitability to know the quality of the product that is flowing through their process unit at any given moment. Process gas chromatographs (PGCs) can provide many plants with some of this critical on-line data, but too often plants must also rely on laboratory GC analysis as backups or quality checks to the PGCs. This is because the laboratory GC analysis provides data on more components at higher resolution and higher sensitivity. In other cases, the information that a plant needs can only be achieved by laboratory GC analysis since limitations in technology prevent the analysis from being performed on a PGC at all. What’s needed is a PGC that can provide repeatable capillary chromatography with pressure programming and temperature-programmable ovens. It also needs to be built to ATEX specifications so that it can be installed in hazardous rated areas. Wasson-ECE’s Eclipse (FID/TCD/PDHID), Neutrino (MSD), and E-VUV (VUV detector) PGCs provide such a solution [1] [2] [3]. These PGCs use convection ovens with precise controls as well as electronic pressure and flow programing to drive the performance and resolving power of capillary column chromatography. The precision of the temperature and electronic pressure controls was proven to demonstrate highly reproducible retention times and peak areas, results rivaling those obtained on laboratory GCs. Furthermore, an extremely broad range of analytes can be detected because of the detectors that these PGCs offer, most notably the MSD. The Eclipse, Neutrino, and E-VUV PGCs provide single analyzer solutions that deliver results for a diverse range of analytes which would typically require several traditional PGCs and the shelter space to house them.
