Gas-Chromatography (GC) is one of the most important techniques used to analyze compounds that can be transformed to a gaseous phase. A precise and stable gas flow control is essential at different points within a GC system, in order to achieve high resolution peaks.
Excellent repeatability is critical for the sampling system. A high turn down ratio of the gas flow provides additional flexibility. In carrier gas control, repeatability and a fast response time provide good peak resolution. With the option for multi-gas in the mass flow controller, different carrier gases can be used. At the detector, high accuracy of flux measurement is critical for measurement performance. In addition, high repeatability reduces deviations at the detector.
