Clarity Control Module SSI PUMPS

Importance of Topic

High-performance liquid chromatography (HPLC) relies on precise pump control to ensure reproducible gradient profiles and flow rates. The integration of SSI pumps into the Clarity chromatography environment enables comprehensive management of mobile phase composition, pressure limits, and real-time monitoring, which are essential for consistent analysis across research and quality control laboratories.

Objectives and Overview

This document describes the installation, configuration, and operation of the SSI pumps control module within DataApex Clarity software. It covers system requirements, communication setup, method and gradient programming, hardware parameters, device monitoring, report generation, and troubleshooting procedures.

Methodology and Instrumentation

• Communication: RS-232 via DB9F-RJ11 cable and Clarity UNI Ruby script.
• Software: Clarity chromatography station with LC Control license and UNI driver.
• Instrumentation: SSI pumps with options for dual-head, high-pressure and micro-pump configurations.
• Configuration: Clarity System Configuration for module addition, DataApex UNI Setup for port autodetection and parameter assignment.

Main Results and Discussion

• Gradient Programming: Interactive table for time, solvent percentages and flow rates; graphical display with dual axis for flow and composition.
• Idle and Standby States: Configurable flow and composition for safe shutdown and post-run conditions.
• Auxiliary Pumps: Separate method setup for auxiliary pump flow settings, pressure limits and purge functions.
• Real-Time Control: Manual flow adjustment during runs, with audit trail recording and automatic method restoration.
• Monitoring and Reporting: Dedicated device monitor windows, status indicators, error handling, and automated inclusion of pump parameters in method reports.
• Troubleshooting: Communication logging via COMDRV.INI configuration to capture RS-232 exchanges for support diagnostics.
