Description
The OI Analytical Eclipse 4660 Purge and Trap Sample Concentrator is a high‑performance automated system designed for the purge‑and‑trap concentration of volatile organic compounds (VOCs) prior to gas chromatography analysis. Engineered to deliver reliable sensitivity and reproducible results, the Eclipse 4660 is widely used for environmental and regulatory testing applications.
This system is optimized for use with GC and GC/MS platforms, providing efficient sample purging, analyte trapping, and thermal desorption to support low‑level VOC determination. Its automated operation helps reduce manual handling, improve consistency, and increase laboratory throughput for routine analytical workflows. The Eclipse 4660 is commonly utilized for methods including EPA 524, 8260, 624, and related purge‑and‑trap protocols, making it well suited for drinking water, wastewater, soil extract, and environmental compliance testing.
This OI Analytical Eclipse 4660 Purge and Trap Sample Concentrator is offered fully refurbished and tested, in working condition.
Includes:
- OI Analytical Eclipse 4660 Purge and Trap Sample Concentrator
- Integrated Purge‑and‑Trap Module
- Power Cords
- 30 Day Warranty
