What is a flow meter and what is its purpose in a gas chromatograph?
Homework Answers
Gas chromatography is a common type ofchromotagraphy used in analytical chemistryfor separating and analyzing compounds that can be vaporized without decomposition. Most common device for measuring a volumetric flow rate is a bubble . These devices are used to determine by measuring the time required for a gas stream to move a soap bubble through a specific volume.

Helium is used in a laboratory as carrier gas for a gas chromatograph. The helium is stored as a pressurized gas in a cylinder initially at 4000 PSIG and is slowly withdrawn from the cylinder. It is important that the helium pressure at the gas chromatograph is constant at 45 PSIG, with a simple single-stage pressure regulator (set at 45 PSIG) installed between the helium cylinder and the chromatograph. In another project in this lab, liquefied ammonia is stored in...
