Clarity Control Module CLUZEAU IGLOO-CIL

Significance of the Topic

Precise temperature control is essential for optimized chromatographic separations. The integration of an external thermostat module into chromatography platforms enhances reproducibility and accuracy of temperature dependent analyses. The ability to directly control the Cluzeau Igloo-CIL unit from the Clarity software creates a fully automated workflow for modern analytical laboratories.

Objectives and Overview

This document outlines the procedures to connect, configure, and operate the Cluzeau Igloo-CIL control module within the Clarity chromatography station. It covers hardware requirements, software setup, method configuration, device monitoring, report integration, and troubleshooting.

Methodology and Instrumentation

Instrumentation

• Cluzeau Igloo-CIL thermostat
• Serial DB9F-DB9F cross cable (RS232)
• PC running Clarity software with LC or GC Control license

Methodology

• Physical connection via a free COM port
• Adding the driver through Clarity System Configuration
