Gas Chromatography

Verify and optimize gas control in gas chromatography

Accurately measure and control helium, nitrogen, carbon dioxide, and other carrier gases with a single instrument in research laboratories. For applications requiring precise regulation, use small mass flow and pressure controllers to deliver stable, repeatable carrier gas control. Optimize your gas chromatography processes with Alicat^®.

Stable, low-flow control. From zero to full scale within tens of milliseconds.
Compact instruments. Save space with highly repeatable BASIS mass flow controllers or EPC pressure controllers that fit in the palm of your hand.
C1D1 environments. Intrinsically safe instruments for Zone 0 and Zone 1 explosive environments mean you can use Alicat on process analyzer systems in the field.

Fast, precise gas control for many environments

Fluctuations in flow rate disrupt the detection of chemical compounds. Tightly regulate carrier gas flow rate with small flow or pressure controllers to ensure accurate compound detection.

Verify GC flows with portable meters to maintain performance integrity.

Applications and use cases

Compact gassing modules save space and simplify design of benchtop bioreactors

Alicat BASIS B Series Compact Mass Flow Meters

Gas control is critical for maintaining optimal conditions for cell growth in bioreactors. In most stirred bioreactors, gas is controlled through a combination of sparging (sub‑surface) and headspace sweeping (super‑surface). Gases such as oxygen and nitrogen assist cell culture growth while removal of carbon dioxide prevents toxic buildup.

Acetylene sample analysis in a CID1 hazardous location

In a North American process laboratory operating within a Class 1, Division 1 (CID1) hazardous area, a gas sampling system monitored post-hydrogenation acetylene conversion from a side‑stream off the main process line.

Learn how the sample was routed through an Alicat IS-Max™ mass flow controller to verify that residual acetylene concentrations were reduced to safe operating levels $
