A key technology is the built-in Cyclone Water Management system that removes water during the thermal desorb step. The high efficiency of water removal allows analysis of polar compounds such as alcohols, ethers, and ketones without interference from water. Degradation of chromatographic columns and maintenance of the GC or GC/MS are also minimized.
Features:
- Patented Cyclone Water Management system removes >96% of water during the thermal desorb step allowing analysis of polar compounds
- Patented Foam Sensor and Foam Buster detect the presence of foam and disrupt it during the purge step to prevent system contamination
- Sparge Overfill Sensor (SOS) prevents overfilling of the sparge vessel and system flooding
- Patented Infra-Sparge Sample Heater ensures consistent sparge vessel temperature conditions for improved compound recoveries and %RSDs
- Color touchscreen with Windows CE software interface (English and Chinese languages)
