Automated water and soil sample processor with 100-vial capacity for use with Eclipse 4760 purge-and-trap concentrators
Improve sample processing reliability and analytical performance with the Model 4100 Water/Soil Sample Processor. This automated instrument is efficiently built to process up to 100 drinking water, wastewater, or soil samples.
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 handle samples carefully, while high-speed injection valves improve the precision of standard addition, reduce the volume of standards used, comply with industry standards, and decrease laboratory operating costs.
A pneumatically actuated vial gripper effectively handles vials with labels and eliminates dropped vials. High-speed 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.
A vial cooling option is available to maintain sample vials at 10 °C or less before analysis for compliance with USEPA Method 524.3. Two 50-position insulated vial racks fit into a cooling base with quick disconnects for easy tubing connection to a recirculating chiller.
Vials containing water are lifted up to engage a sample probe, aspirate, and fill a loop with the 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 delivers them to the trap in the P&T instrument.
Integrated into the tower of the 4100 are two 3-mL reservoirs and electronically controlled high-speed injection valves that automate the addition of internal standards or surrogate matrix spike standards. An option allows the expansion of standard reservoirs and injection valves from 2 to 4 separate channels to support operation with tandem purge-and-trap instruments.
