In gas chromatography, GC, it is essential to precisely know the flow rate of the column, detector and carrier gas. Also, with volumetric flow meters no adjustments are needed when switching from one gas stream to a stream of different composition .
So for example, an analyst can immediately change from measuring nitrogen from a GC detector to helium split rate from an injection port, to methane from an anaerobic digestion vessel. If a mass flow meter is used, the analyst must change instrument settings and purge the flow meter of the initial gas before accurate readings can be taken. The volumetric measurement principle along with the ability to withstand aggressive and corrosive gases, makes ReciFlow is a good choice for gas chromatography applications.
