4100 Purge & Trap Autosampler

The OI Analytical 4100 Water / Soil Sample Processor automates the handling and processing of samples in 40-mL VOA vials for purge-and-trap analysis of volatile organic compounds (VOCs) in accordance with U.S. EPA methods.

The 4100 efficiently processes up to 100 drinking water, wastewater, or soil samples and operates with a single or dual Eclipse 4660 purge-and-trap instruments.

The 4100 is equipped with an innovative pneumatically-actuated cylindrical vial gripper that surrounds and conforms to each vial. The VOA Constrictor mechanism lifts and transports 40-mL VOA vials to and from the sampling station with unsurpassed reliability.
