GC Sample Introduction | Purge and Trap Concentrator

Maximize your laboratory’s efficiency and investment with OI Analytical’s state of the art Gas Chromatography (GC) Systems. We offer a line of fully integrated, advanced GC systems, and sample introduction systems. Our portfolio includes turnkey GC systems with a variety of selective detectors and automated purge and trap sample introduction instruments.  

4551A Water AuoSampler

The extremely compact 4551A Water Autosampler fits strategically under the 4760 Eclipse to save bench space. The instrument precisely transfers water samples from standard 40-mL volatile organic analysis (VOA) vials to the sparge vessel of the 4760 Eclipse for purging. A removable spiral autosampler tray holds 51 sample vials for fully-automated operation. Our optional LV-20 Standards Addition Module adds internal standards, surrogate or matrix spike standards, and reduce the volume of standards used.

4100 Sample Processor

Say goodbye to handling and processing samples for purge-and-trap analysis of volatile organic compounds (VOCs). The 4100 Sample Processor is designed to operate with (single or dual) Eclipse 4760 purge-and-trap sample concentrators. You can trust the VOA Constrictor™ vial gripper technology to carefully handle samples, while high-speed injection valves improve the precision of standard addition, reduces the volume of standards used, and decreases laboratory operating costs.

4760 Purge and Trap Sample Concentrator

The Eclipse 4760 Purge and Trap Sample Concentrator combines our 30+ years of VOC experience in one highly-productive instrument. Users can expect faster cycle times, higher sample throughput, and exceptional reliability. The purge-and-trap technique involves multiple complex processing steps. Patented components of the Eclipse 4760 remove uncertainty, improve instrument operation, accuracy, and overall analytical performance. Use in conjunction with our Model 4100 Water + Soil Sample Processor or Model 4551A Autosampler to further increase sample throughput and lab productivity.
