Importance of the Topic

Headspace sampling provides an efficient approach to analyze volatile compounds while minimizing manual handling and ensuring sample integrity. Integrating the HT200H autosampler into a chromatography data system streamlines workflows, reduces variability, and enhances laboratory productivity.

Aim and Overview of the Study

The presented manual details configuration and operation of the HT200H Headspace control module within the Clarity chromatography station. It guides users through hardware installation, software setup, and practical use cases to achieve fully automated headspace analysis.

Methodology and Instrumentation

• HT200H Autosampler: headspace sample preparation including conditioning, shaking, and injection.
• Clarity Control Module: software driver enabling direct serial communication over RS-232 (DB9F-DB9M) at 9600, n, 8, 1.
• GC Synchronization: digital I/O connections (Start, Ready signals) via 15-pin connector for coordinated injections.
• Software Setup: System Configuration in Clarity to add and configure the HT200H, including communication ports, oven/syringe temperature, and optimized sequence mode.
• Method Parameters: Basic settings (conditioning time, oven and syringe temperature, shaker timing) and Advanced settings (injection volume, prefill, speeds, multi-injection options).
