OI Analytical Eclipse 4660 Purge and Trap Sample Concentrator (AS-IS for parts)

Product Description
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.

Operating Principle
The Eclipse purges (sparges) VOCs from liquid, solid, or gaseous (from a solid support) samples using a regulated flow of inert gas for a fixed time period. Analytes stripped from the sample (or transferred from an upstream autosampler) concentrate onto a cooled sorbent trap specific for the application. The trap heats rapidly and a valve switches, desorbing the analytes as a plug onto the GC column using a reversed carrier gas flow. The Cyclone Water Management system keeps water, which transferred from the sample matrix to the trap during sparging, within the concentrator. The water management fitting bakes and vents residual compounds and trapped water, reducing interference with subsequent reconcentration, separation, or detection of analytes.

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 pH Detect** module automates sample pH measurement
