Gas Chromatography
Verify and optimize gas control in gas chromatography
Accurately flow helium, nitrogen, carbon dioxide, and other carrier gases with a single instrument. Maintain accurate gas chromatograph outputs with stable, repeatable mass flow control.
- Stable, low-flow control. From zero to full scale within tens of milliseconds.
- Versatile gas compatibility. One controller can measure 98+ gases and custom gas blends.
- 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.
Applications
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.
