3 Introduction Multi-dimensional Valves: Valves allow for a custom analysis of complex sample streams. Application Highlights Flame Ionization Detector Flame Ionization Detector (FID) is used to A flame ionization detector (FID) is detect used the to C 1 detect through the C 7 paraffins C and olefins to a lower detection limit of 20 1 through C ppm, except for 7 paraffins and olefins to a lower trace detection peaks eluting limit of on 20 the ppm. tail of a major component. Capillary Columns: Capillary columns have a higher number of theoretical plates than packed columns and when coupled with multi-dimensional valves offer a powerful solution to the most complex analyses. Thermal Conductivity Detectors A thermal conductivity detector (TCD) is used to detect hydrogen in a nitrogen carrier to a lower detection limit (LDL) of 100 ppm. A second TCD is used to detect the other permanent gases in a He carrier to an LDL of 200 ppm. Agilent 7890A Interface: Our solutions are built around the newest Agilent GC. This allows for easy integration into your lab or process. Electronic Pressure Control Electronic pressure control (EPC) allows for an analysis of C 1 through C 7 olefins and benzene with a run time of less than 15 minutes. EPC pressure programming provides a fast analysis for higher sample throughput. Ph
