Verify and optimize carrier gas control in gas chromatography

Maintain accurate gas chromatograph outputs with stable, repeatable mass flow control.

  • Stable, low-flow control. Even in low flow conditions, Alicat mass flow controllers provide stable flow from zero to full scale within tens of milliseconds.
  • Versatile gas compatibility. One controller can measure 98+ gases and custom gas blends, including common inert gases like N2, He, Ar, and CO2.
  • Easy to integrate and use. Devices come standard with 6-button backlit displays for easy control, or you can connect via a variety of industrial communication protocols.

Mass flow and pressure control enables full system stability

Fluctuations in flow rate disrupt the detection of chemical compounds. Tightly regulate carrier gas flow rate to ensure accurate compound detection.

Electronic pressure control maximizes system stability

Maintain constant chromatograph pressure using electronic pressure controllers with small footprints and IP67 ratings for washdown environments.
