ECOM ECS22 ISOCRATIC PREPARATIVE SYSTEM

Importance of Preparative Chromatography

Preparative liquid chromatography is a cornerstone technique for isolating and purifying target compounds at scale. It plays a critical role in pharmaceutical development, natural product research and industrial process optimization.

Objectives and System Overview

The ASP2200X (ECS22) isocratic preparative system integrates UV diode array detection, preparative pumping, fraction collection and mobile phase management into a unified workflow. The goal is to streamline high‐capacity separations with minimal setup complexity.

Methodology and Used Instrumentation

• TOY18DAD H 400 UV diode array detector: Simultaneous measurement at four wavelengths (200–400 nm) or full spectral scanning; standard PLCC 15 preparative flow cell.
• ECP2200 preparative pump: Isocratic operation with 0.1–250 mL/min flow range and up to 30 MPa pressure; features a learning algorithm for pulsation suppression and built-in diagnostics.
• ECV2010 fraction collector: Rotary valve with 10 positions for precise low-volume fractionation.
• ECB2006 bottle box: Secure mounting for mobile phase reservoirs on isocratic systems.
• Preparative injection valve: Manual 1/8″ injector with a 2 mL sample loop.
• ECOMAC software: Centralized control of all modules, gradient design, method automation and fraction collection; communication via RS232 or Ethernet without requiring an external A/D card.

Main Results and Discussion

The integrated system delivers stable isocratic flows across the full operational range, reliable multi-wavelength detection and efficient fraction handling. Networked connectivity simplifies data acquisition and remote operation, while built-in software drivers ensure seamless device integration.
