The ESA Model 584 solvent delivery module offers significantly improved solvent delivery performance through improvements in solvent-delivery control firmware. With an automatic pulsation-correction mechanism and high-speed micro plunger drive, it achieves pulse-free solvent delivery even at micro-flow-rate ranges below 50µL/min. Enhanced Solvent Delivery
Flow-rate accuracy and precision in the micro-flow rate region have been improved with the addition of an improved check valve design and modifications to the solvent delivery control method.
Improved Durability
New and improved sapphire plungers with optimized crystal structure and a precision plunger-holding mechanism provide long-lasting performance and enable stable solvent delivery.
Features
- Dual Parallel Plungers - provide low pulsation and greater seal life.
- Micro Volume Piston Displacement - 10 µL per plunger stroke, gives improved LOD with electrochemical detection
- Flow Rate Range of 0.0001 - 10 mL/minute - usable for analytical, microbore and LC-MS applications
- Automatic Seal Wash - prolongs piston seal life for greater reliability.
- Enhancement Package - for reduced noise with electrochemical detection.
- Electronic Diagnostics - for easier maintenance.
- Improved Fluidics - made more reliable and easier to service
- High Gradient Accuracy and Precision - for greater reproducibility
