- Holds 100 samples in two 50-position vial racks
- Operates with one or two Eclipse 4660 purge-and-trap instruments
- Vial cooling option keeps vials at 10°C or less in accordance with USEPA Method 524.3
- VOA Constrictor™ vial gripper has built-in vial sensor
- Standard Addition Module has two 3-mL reservoirs, expandable to four 3-mL reservoirs
- High-speed injection valves in Standard Addition Module inject programmed volume with no excess or waste
- VOA View Windows®-based software offers an intuitive user interface with a real-time view of sampling progress
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.
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 and International standards. The 4100 is designed to efficiently process up to 100 drinking water, wastewater, or soil samples and operate with a single or dual Eclipse 4660 purge-and-trap sample concentrators. Innovative technologies built into the 4100 improve sample processing reliability and analytical performance. A pneumaticallyactuated vial gripper effectively handles vials with labels and eliminates dropped vials. Highspeed injection valves improve the precision of standard addition, significantly reduce the volume of standards used, and decrease laboratory operating costs for expensive standards.
VOA View software is a Windows®-based GUI that enables users to program methods, sequences, and internal standard addition. The VOA View run screen visually depicts water and soil samples, the progress of vials that have been processed, and provides details of the method being run.
VOA Constrictor Vial Gripper
The OI Analytical 4100 is equipped with an innovative pneumatically-actuated cylindrical vial gripper. The VOA Constrictor™ mechanism grips, lifts and transports 40 mL VOA vials to and from the sampling station with exceptional reliability. A built-in sensor enables the gripper to detect and confirm the presence of a vial or signal if a vial is missing.
Vial Cooling Option
A vial cooling option is available to maintain sample vials at 10 °C or less prior to analysis for compliance with USEPA Method 524.3. Two 50-position insulated vial racks fit into a cooling base fitted with quick-disconnects for easy connection of tubing to a recirculating chiller.
Water / Soil Sampling Station
Vials containing water are lifted up to engage a sample probe, aspirate and fill a loop with sample for transfer to the P&T instrument. Vials containing soil samples are lifted to engage a probe that injects a programmed volume of clean or spiked water, heats and stirs the sample to purge VOCs from the matrix and deliver them to the trap in the P&T instrument.
Automated Standard Addition
Integrated into the tower of the 4100 are two 3-mL reservoirs and electronically controlled high-speed injection valves that automate addition of internal standards or surrogate matrix spike standards. An option allows expansion of standard reservoirs and injection valves from 2 to 4 separate channels to support operation with tandem purge-and-trap instruments.
