ESA Model 584 Solvent Delivery Module

Optimized for HPLC electrochemical detection, the Model 584 Solvent Delivery Module offers pulse-free solvent delivery – even at micro-flow-rate ranges below 50 μl/min – and offers the following features and benefits:

• Dual parallel plungers – provide low pulsation and greater seal life
• Micro-volume plunger displacement – 10 µL per plunger stroke, improves limits of electrochemical detection
• Flow rate range of 0.001 - 10 mL/minute – can be used in analytical, microbore, and LC-MS separations
• Automatic seal wash – prolongs plunger seal life for greater reliability
• Enhancement package – for reduced noise and lower limits of detection with all HPLC detectors
• Electronic diagnostics – for easier maintenance
• Improved fluidics – more reliable and easier to maintain
• High-gradient accuracy and precision – for greater reproducibility
