Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.
Pressure and Gas Chromatography
Gas chromatography uses stationary and mobile phases for separating and analyzing mixtures according to “Chromatography Composition Measurement,” in The Measurement, Instrumentation, and Sensors Handbook. To perform the necessary steps, the typical gas chromatograph has several different aspects. It starts with a pressure regulated carrier gas supply. The carrier gas pressures are typically 34 to 69 kPa (5 to 10 psig) to 138 to 340 kPa (20 to 50 psig) at gas flow rates of 1 mL min-1 or less. If the data system monitors and records the supplied pressures, pressure sensors would also be used.
To measure this range of pressures, All Sensors SPM 401 Series of media isolated sensors would provide a good solution since process control and monitoring systems are target applications.
