    The N901 performs Hydrocarbon (HC) analysis by means of Gas Chromatography (GC) with Flame Ionization Detection (FID), using a preparative method of automatic injection, separation, and fraction collection. GC in the N901 employs a carrier gas (an inert gas that does not get measured), of 99.999% or UHP-grade Nitrogen (N ) to move the sample gas into the FID for analysis.

    “Smart Modules,” which conduct local operations, such as activating valves or controlling manifold temperature. There is also the Sensor Module, which is comprised of the gas sensor and its operational components. The Sensor Module calculates gas concentrations and may command the Smart Modules.
