ECOM ECP2200 PREPARATIVE PUMP

Importance of the Topic

Preparative pumps capable of high pressure and stable flow are critical in liquid chromatography when isolating and purifying compounds at scale. These instruments ensure reproducibility and efficiency in synthetic chemistry, pharmaceutical development and industrial process control.

Objectives and Overview

This document introduces the ECP2200 preparative pump, highlighting its design goals, performance characteristics and adaptability to high-pressure gradient operations. Emphasis is placed on stability at low flow rates and the integration options for multi-pump configurations under PC control.

Used Instrumentation

• ECP2200 Preparative Pump featuring dual parallel pistons (3/8” diameter).
• PC-based control via RS232, optionally LAN and USB interfaces.
• Software support through ECOMAC and Clarity platforms.
• Optional modules: pressure sensor, gradient valve controller, LAN/USB communication board.

Main Results and Discussion

The ECP2200 delivers flow rates from 0.5 to 250 ml/min and sustains up to 30 MPa pressure at 100 ml/min, decreasing linearly to 15 MPa at maximum flow. Flow adjustment accuracy is ±2% with repeatability within ±1% at 0.1 ml/min increments. Wetted materials such as stainless steel, PEEK and ceramics ensure chemical compatibility when handling buffered solvents. The parallel piston design provides exceptional stability at low flow, while back-flushing extends maintenance intervals. Multi-unit gradient control enables complex solvent programming across two to four pumps simultaneously.

Benefits and Practical Applications

• High-pressure capability supports preparative separations of complex mixtures.
• Stable low-flow operation enhances fraction collection precision.
• Flexible communication options facilitate integration into automated systems.
• Robust construction and material selection suit a wide range of solvents and buffers.

Future Trends and Possibilities

Advances in pump sensor integration and microfluidic flow control are expected to improve pressure monitoring and gradient fidelity. Further miniaturization may expand applications to lab-on-chip preparative separation. Enhanced software analytics could enable predictive maintenance and real-time performance optimization.

Conclusion

The ECP2200 pump offers a reliable and versatile solution for preparative liquid chromatography, combining high pressure, precise flow control and modular expandability. Its design addresses both routine and advanced separation challenges, making it a valuable tool in research and industrial environments.
