CALIDUSTM 101 HT Ultra-Fast GC Total Petroleum Hydrocarbons (TPH) in Soil and Water
GC analysis for TPH (C8-C44 hydrocarbons) in Soil and/or Water extracts using soxhlet, continuous liquid/liquid, or SPME. Viable for laboratory, at-line, or transportable analysis in less than 4 minutes.

The Sample Processing Module with a standard split/splitless injection port, incorporating either a syringe through septum injection, or Auto Sampler delivers the sample to a Programmed Temperature Column Module (PTCM). The inlet includes septum purge to prevent bleed components from entering the system.
The PTCM is controlled by the method. It contains a MXT-1 High Temperature Resistively Heated Stainless Steel Capillary Column and is operated in a temperature programmed mode. The column provides the separation of the hydrocarbons in the liquid extract. (See Figures 2 & 3)

The analyzer includes ChromPerfect chromatography data system, fully integrated, running on a Windows PC, for calculating TPH concentrations for any carbon range from C8-C44.
The analysis of Total Petroleum Hydrocarbons (TPH) is a far-reaching analysis that is frequently used in several industries. In many cases, distinct speciation is not as important as quantitation across specific carbon ranges.
Methods like Diesel Range Organics(DRO) by EPA Method 8015, ISO 9377-2, and EN 5991/7219 utilize this quantification method, and can have run times of 30 minutes or more. By taking advantage of the Calidus patented technologies, these analytical methods can now be run in less than 4 minutes. Increasing sample throughput, laboratory/process capabilities, and decreasing backlogs.
