The PGC5007 Total Sulfur Analyzer performs analysis for a range of streams, liquid and vapor, from natural gas to gasoline and diesel. A fixed volume of sample from the process stream is injected via a sample inject valve. Air transports the sample into the furnace, where it oxidizes the sample to carbon dioxide, water and sulfur dioxide.[…]
Process gas chromatographs use a measurement method called gas chromatography (GC) that is a type of chromatography used in analytical chemistry and process industry for separating and analyzing components that can be vaporized without decomposition. Typical uses of process gas chromatography include testing the purity of a particular substance, or separating the different components of a mixture (the relative amounts of such components can also be determined). In some situations, GC may help in identifying a compound. In preparative chromatography, process gas chromatographs can be used to prepare pure compounds from a mixture.
Gas chromatography is a widely accepted technique for monitoring and analyzing hydrocarbon mixtures. Installed in the field or on-line as an individual analyzer or part of an analytical system, gas chromatographs provide superior accuracy and repeatability across a wide dynamic range of components for process and natural gas applications.
Process gas chromatographs are used for separating and analyzing chemical compounds in the gas phase of industrial processes. GC instruments vaporize and distribute samples between a stationary and mobile phase, whereby a chemically inert gas carries molecules through a heated column.
The gaseous compounds being analyzed interact with the walls of the column, which is coated with a stationary phase. This causes each compound to elute at a different time, known as the retention time of the compound. The comparison of retention times is what gives gas chromatographs their analytical usefulness.

MCZ Easythene, the easiest ethylene monitor
Ethylene monitor, for control of catalysts in CO2 fertilization systems or for C2H4 detection for ripening process control. Ethene acts as a hormone in the ripening process of plants. To avoid destruction of plants and fruits because of high ethylene levels it is necessary to know the real amount of C2H4 in the atmosphere. To[…]
