Eclipse 4760 Purge & Trap Sample Concentrator HIGH-PERFORMANCE INSTRUMENT FOR ACCURATE, RELIABLE VOC ANALYSIS The Eclipse 4760 Purge & Trap Sample Concentrator combines our 30+ years of VOC experience in one highlyproductive instrument. Remove more than 96% of water during desorption with our Cyclone Water Management system Prevent system contamination with foam sensing and purge abort technologies Infra-Sparge Sample Heater ensures consistent sparge vessel temperature conditions for improved compound recoveries and %RSDs Use in conjunction with our Model 4100 Water and Soil Sample Processor or Model 4551A Autosampler to further increase sample throughput and lab productivity.

Eclipse 4760 Operating Principle: The Eclipse purges VOCs from liquid, solid, or gaseous matrices using a regulated flow of inert gas for a fixed time period. Analytes stripped from the sample (or transferred from an autosampler) concentrate onto a sorbent trap specific for the application. The trap heats rapidly, desorbing the analytes as a “plug” onto the GC column using a reversed carrier gas flow. The water management fitting removes the trapped water, minimizing the chance of introducing excess moisture into the GC. Feature Power requirements Foam Buster Foam Sensor Sparge Overfill Sensing...
