A key technology is the built-in cyclone water management system, which removes water during the thermal desorption step. The high efficiency of water removal enables the analysis of polar compounds such as alcohols, ethers and ketones without interference from water. Degradation of chromatographic columns and GC or GC/MS maintenance are also minimized. Characteristics:. The patented cyclone water management system removes over 96% of water during the thermal desorption step and enables the analysis of polar compounds. The patented foam sensor and foam destroyer detect the presence of foam and eliminate it during the flushing step to prevent contamination of the system. The flush overfill sensor (SOS) prevents the induction bowl from overfilling and flooding the system. The patented Infra-Sparge sample heater ensures consistent temperature conditions in the induction tank for improved compound recoveries and %RSDs. Color touchscreen with Windows CE software interface (English and Chinese languages). Specifications:. Induction tank:. 5ml standard, 25ml optional. Sample heater (option): Infrared heating of the induction bowl with in-situ temperature measurement and feedback control. Foam sensor (option): Optical sensor detects foam in the induction bowl and stops the run to prevent contamination of the sample path. Flush overfill sensor (option): Capacitive sensor detects the presence of water in the induction bowl to prevent the introduction of a new sample and overfilling if the previous sample has not drained properly. pH DetectTM module (option):. Automatically measures sample pH with date and time stamps stored in a log file for reporting or transmission to a LAN/LIMS system. Autosamplers (options): 4551A (water samples), 4100 (water/soil samples). Cases:. 3.175mm OD x 2.227mm ID (0.125" OD x 0.105" ID). Trap heating:. Direct resistance heating. Trap temperature:.
