GC Flow Controllers Products & Reviews

Flowmeters that can measure flammable gases are becoming mandatory due to the increased use of hydrogen in chromatography. With its Ex rating, the Restek ProFLOW 6000 meter is designed specifically with explosive and flammable gases in mind.

Compact Gas Flowmeter for use with GC

On-line sampling module for the UNITY-xr™ thermal desorber

Accurate and repeatable gas flow measurement. Accurate and repeatable gas flow measurement is fundamental to obtaining good results from your thermal desorption-gas chromatograph. The traditional bubble flowmeter, relying as it does on the reaction time of the operator, is a potential source of error.The digital flowmeter eliminates this source of error and makes gas flow easement easier and more accurate. The flowmeter allow…

Agilents Precision Gas Flow Meter is the ultimate gas flowmeter for chromatography applications. This handheld flowmeter incorporates industry leading performance and features in a highly accurate and reliable package. The inherent stability of the rugged, solid state components allows us to provide the longest calibration interval on the market, all traceable to NIST standards.

Use this automated and user-programmable helium conservation module on an Agilent 8890, 8860, or 7890 GC to significantly reduce your helium consumption, especially when combined with Agilent Gas Saver.

High-Performance Gas Flow Control for OEMs

Patented G-Cal permeation tubes offer a proven and repeatable means of generating a desired gas or vapor concentrations. The permeant gas escapes through the proprietary membrane system and mixes with a carrier gas (nitrogen is the most common) at a controlled flow rate to obtain a known mixture in ppm or ppb. Applications include calibration of gas monitoring systems and chromatographs, accuracy check of gas detectors, and ge…
