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
Sparge Vessel 5-mL standard, 10-mL, 25-mL optional
Sparge Overfill Sensor (Option) Optional capacitance sensor detects presence of water in sparge vessel to prevent introduction of a new sample and overfilling if the previous sample has not drained properly
pH DetectTM Module (Option) Optional module automatically measures the pH of samples with date and time stamps stored in a log fi le for reporting or transfer to a LAN/LIMS system
