OptoDRS™ Sample Interface

The OptoDRS™ (Dynamic Reflux Sampler) integrates the OptoAST™ Sampling Interface with a Dynamic Reflux Sampler (DRS). The OptoDRS is responsible for in-process sample conditioning by removing liquids as well as many of the particulate contaminants transported within the gas stream.
By using the OptoDRS sampling interface, hazardous process fluids are maintained at the sample tap. This minimizes the risk of exposure or leaks when compared with the use of heated sample transport lines.

  • Pipe-centric Sampling with Optical Compositional Analysis
  • Combination of the OptoAST with a Modular OptoDRS
  • Reduced Cost for Process Analyzer Systems Where it Counts Most, i.e. Infrastructure Costs
  • More Reliable Sampling by Conditioning Hot, Dirty, and Wet Streams
  • Allows Sample Return to the Process by Operating at High Pressure and Low Flow (no flare, no waste)
