Instrument Regulators/Controllers

Upgrading instrument pressure regulators and flow controllers can lead to improved system performance, and is a much less expensive option than the purchase of a new instrument. For example, an older system that employs column outlet pressure regulation can be upgraded to operate with backpressure regulation, allowing the user to:

  • Conserve carrier gas
  • Set linear velocity more accurately
  • Use hydrogen carrier gas more safely

We offer instrument regulators/controllers made by Porter Instrument Company that are specifically designed for GC instrumentation. They are suitable for panel mounting, can be used to 160 °F, provide bubble-tight shutoff to 250 psi (helium), and have 1/8 in. brass Swagelok connections.
