Eclipse Purge-and-Trap Sample Concentrator


Eclipse Purge-and-Trap Sample Concentrator


The Gold Standard In Volatiles Analysis

The Eclipse 4660 Purge-and-Trap Sample Concentrator processes samples for analysis of volatile organic compounds (VOCs) by gas chromatography (GC) or gas chromatography/mass spectrometry (GC/MS). Innovative, patented components within the Eclipse significantly improve sample processing steps of the purge-and-trap technique. 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.

What we did
  • 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)
  • Optional pHDetect™* module automates sample pH measurement (*patent pending)
