4760 Eclipse P&T

High-Performance technology for Accurate, Reliable Volatiles Analysis

The Eclipse 4760 Purge and Trap Sample Concentrator sets a new standard for ease-of-use for volatile organic compound (VOC) analysis. The new 4th generation system includes the popular features from the Eclipse platform that chemists around the world rely on for accurate, dependable results along with technology enhancements, intuitive software, and a slim-line, open architecture design that saves bench space and allows easy access to components. Engineered to increase efficiency, and ease of operation, the Eclipse 4760 maximizes throughput, simplifies troubleshooting, and minimizes system downtime for fast accurate, dependable results. Fully complies with all USEPA CLP, State, EU, and ISO VOC methods, protocols, and audit requirements.

- Run more samples in less time and maximize laboratory throughput and profitability

- See the system’s status instantly at a glance with TruColour™ LED indicator

Patented Cyclone Water Management™ system removes >96% of water during the thermal desorb step allowing analysis of polar compounds & minimizing water transfer to the GC column

Intuitive, simplified user-interface and Trap View™ software

Heats sparger during bake to reduce carryover

Patented technologies for foam sensing and purge abort 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

Direct resistance heating of the trap at >1,000 °C/min eliminates the need for a trap preheating step and decreases overall purge and trap cycle time
