OI Analytical 4100 Water/Soil Sample Processor


4100 Water/Soil Sample Processor

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.     
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.


  • Holds 100 samples in two 50-position vial racks       
  • Operates with one or two Eclipse 4760 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, expendable to four 3-mL reservoirs       
  • High-speed injection valves in Standard Addition Module inject programmed volume with no excess or waste
