Gas analyzer full component analysis

Gas analyzer full component analysis

Gas chromatography method:

Fast analysis speed, gas chromatography analysis speed is fast, microcomputers are increasingly widely used in chromatographic analysis, and data processing is also very fast.Widely applicable, gas chromatography can analyze gases and volatile liquids, while non-volatile liquids and solids can be converted into volatile substances for chromatographic analysis. Not only can it analyze organic compounds, but it can also analyze some inorganic substances.

Gas analyzer full component analysisApplication scope:

Coal to gas conversion or gas based regional heating with heat and steam as the main sources should be the current main market. To achieve balanced heating in the large-scale heating network, the integration and complementary development of gas regional heating and urban large-scale heating network.

Analysis components:

The integrated machine for analyzing the composition and calorific value of natural gas can achieve full analysis of oxygen, nitrogen, methane, ethane, carbon dioxide, propane, isobutane, n-butane, n-pentane, isopentane, and hydrocarbon components above C6+in natural gas with a single injection. The standard natural gas calorific value can be used for component analysis of natural gas and liquefied petroleum gas, as well as for component analysis of various gases prepared with hydrogen, nitrogen, methane (or propane; liquefied gas) as raw materials. Natural gas calorific value analyzer, natural gas whole component analyzer.

Thermal conductivity detector:TCDThe sensitive element is a hot wire, such as tungsten wire, platinum wire, rhenium wire, and a bridge is composed of hot wires. After passing through a constant current, the temperature of the tungsten wire increases, and its heat is transferred to the pool wall through the surrounding carrier gas molecules. When the tested component enters the thermal conductivity cell together with the carrier gas, the thermal conductivity of the mixed gas is different from that of the pure carrier gas (usually lower than that of the carrier gas), and the heat transmitted by the tungsten wire to the cell wall also changes, resulting in a change in the temperature of the tungsten wire and a change in its resistance, which in turn generates an unbalanced potential at the output end of the bridge as a signal output.TCDIt is also a universal detector, but its sensitivity is relatively low and cannot meet the requirements of trace analysis. It is mainly used in the petrochemical industry for detecting gas components.
