Features of the Continuous Solids Sampler

The GR Sprenger Engineering, Inc. Continuous Solids Sampler was developed to collect a very small, yet representative sample from a stream of flowing solids. Its design provides for continuously extracting a 0.015% to 5.0% fraction of the process stream. The device is mounted as an integral section of the process line. This sampler is therefore ideal for Product Quality Assurance and regulatory compliance.


  • Continuous Sample Collection.
  • Entire process stream passes through the Sampler.
  • Sample Fraction is 0.3 to 0.8 lb./ton.
  • No moving parts.
  • No timers or electronic controls required.
  • Standard sizes from 4" to 12" for flows from 1 to 250 tons/hr.
  • Custom models for higher flow or sampling rates are available.
  • Operating Temperatures to 1000 degrees F.


  • All Product has an equal chance of being sampled.
  • Minimal installation expense.
  • No electronic controls installation or maintenance.
  • Minimal operations expense.
  • Small sample volume minimizes sample handling and storage.
  • Provides basis for high Product Quality Assurance.
  • Provides an inexpensive method of collecting Retained Samples of each batch or lot.
  • Provides basis for validated Sampling and Analysis.


  • Custom Design for specific Product Characteristics.
  • Installation Coordination.
  • Acceptance Testing.
  • Quality Assurance Planning.
  • Sampling and Analysis Planning.
  • Field Service.
