According to GB/T3727-2003《Determination of ethylene, propylene trace water for industrial use》

The instrument used in the pretreatment on prior analysis of liquid hydrocarbons and their derivatives or other saturated vapor pressure at room temperature and more than one atmospheric pressure substance liquefied，Before the invention of the product of Rishang Instrument，In just a small amount of liquid substance will have intermittent instantly vaporized function in gas chromatography gasification chamber (Note-like device), Unable to achieve a  controlled gasification process of continuous composition for  a lot of liquefied gas.This technology is for the blank of domestic and foreign。Liquid sample material can be converted to gas on our original invention functions，Gaseous substances meet constant composition after conversion, suitable temperature, a slight positive pressure, flow rate and other characteristics can be controlled．Since 1997, development and manufacturing of liquid hydrocarbon sampling flash vaporization injection products, now Rishang instrument has five patents related.Our products have been sold all over the world. The android tablet PC upper computer interface ( can also provide the Windows operating system interface) which is Launched in 2015,   compatible with the original outstanding lower computer a machine hardware resources, a bluetooth technology is used for lower computer to the upper computer to realize a data transmission, crossed the traditional touch screen technology. Tablets or other PC also has strong resources of the network technology, which can provide remote data sharing, testing, monitoring and control functions , and give consideration of after-sales service functions such as maintenance, maintenance, fault diagnosis. This product applies to the following various items of analysis:

★Scope of application： ★Analysis on Ethylene, propylene and butene isomers of trace water  use with Coulometric Method for trace water and  dew point analyzer

★Various industrial Analysis of olefins trace oxygen, use with trace oxygen analyzer

★Using on Liquid hydrocarbon composition analysis with gas chromatography

★Analysis on Various types of industrial used olefin trace of carbon monoxide, carbon dioxide, with the use of a gas chromatograph

★Analysis  on various types of refrigerants and SF6 trace water

★Analysis of liquid hydrocarbons and arsenic with UV trace sulfur, and other substances fluorescence sulfur analyzer fixed or fixed microcoulometry sulfur analyzer using

Principle and the method

The gasification principle of flash vaporization sampling sampler of Liquid hydrocarbon is similar with the gas phase chromatograph sample injection device，Chromatographic injector is intermittently trace gasification，Gasification  of flash vaporization sampling sampler of Liquid hydrocarbon is a continuous constant，Flash gasification is a continuous instant gasification process，Thereby ensuring that the composition of the sample is composed of exactly the same with liquid in cylinders sampler  after gasification . This is our new concept when Flash vaporization sampling sampler of Liquid hydrocarbon was invented in 1999 that we proposed——The same  components of gasification。The company has led the technology of being can be liquefied gas injection which is higher than the atmospheric pressure on saturated vapor pressure at room temperature, can now be with chromatographic when using this technique, you can directly put the flash technology into the gas chromatograph, it has a great convenience for users.
