Static Mixers

HyperShear™ Static Mixers

  • Static Mixers are available in Standard HPLC, Ultra HPLC, Biocompatible PEEK and In-Line Combo Series
  • Standard HPLC Mixers are constructed from 316 stainless steel with volumes ranging from 0.5 μL to 15.0 mL and with pressure to 6,000 PSI.
  • Ultra HPLC Mixers are constructed from 316 stainless steel with volumes ranging from 0.5 µL to 1.5 mL and pressure to 18,000 PSI.
  • Biocompatible Mixers are constructed from PEEK as wetted material with volumes ranging from 0.5 μL to 1.5 mL and with pressure to 3,000 PSI.
  • In-Line Combo Mixers are suitable for seeking to optimize mixing volumes at flow rates below 100 μL/min. and have the ability to customize a mixing volume which is perfectly tuned to match the separation system.
  • ASI Hypershear Mixer enables pharmaceutical assay.  read this article
  • Static Mixer Development Kits for the equipment manufacturer or the scientist that needs to optimize a separation or process, are available.

Linear Gradients - High Pressure Mixing

The best choice is usually a compromise between delay volume and mixing noise - more mixing volume will reduce mixing noise but at the cost of more delay volume.  The upper limits to mixing volume will be the maximum delay time that can be tolerated, and possible distortion (tailing) of the gradient at the beginning and end of the gradient. The lower limit will be defined by the amount of mixing noise that can be tolerated. The following cartridge volumes are a compromise between these two limits.

 

For illustration ONLY

  1. When mixing noise is limiting, use Flow Rate, Column 1
  2. Mixing delay volume is sometimes referred to as dead volume. It affects peak shape or dispersion. Use Flow Rate, Column 2 when this is critical.
