Description
The HP 7694 Headspace Autosampler is a robust and widely adopted static headspace sampling system designed for automated analysis of volatile compounds when coupled with HP / Agilent gas chromatographs. Featuring an automated 44‑sample tray, the HP 7694 enables unattended operation, consistent vial heating, and reproducible headspace injections, making it ideal for routine and regulated laboratory workflows. With a highly inert sample path, programmable methods, and overlapping sample processing, the HP 7694 minimizes matrix effects while improving throughput and data consistency. It integrates seamlessly with Agilent GC systems, supporting GC‑FID and GC‑MS applications across multiple industries.
This refurbished HP 7694 Headspace Sampler has been fully tested and verified to be in proper working condition by Alliant Scientific.
System Includes:
- HP 7694 Headspace Autosampler
- Automated 44-sample tray
