High Purity Industrial Gases Specialty Stadard Mixture Gas
High purity industrial gas professional standard gas mixture
Product Information:
1, gas mixture, refers to the gas containing two or more than two kinds of effective components, or although it is not effective components but its content exceeds the prescribed limits. A mixture of gases commonly used in engineering. Mixed gases are usually studied as ideal gases.
2, is refers to the concentration of uniform standard gases, good stability and accurate determination of the standard value, they have the repetition, save and basic function of the value, in physics, chemistry, biology and engineering survey in the field of measuring instruments used for calibration and measurement process, the accuracy of the evaluation method of measurement and testing laboratory detection ability, determine the characteristic value of material or product, Carry out quantitative arbitration, etc.
3, common standard gases by use include: gas alarm standard gas, power energy standard gas, petrochemical standard gas, environmental protection monitoring standard gas, medical and health standard gas, instrument and meter standard gas, etc..

A mixed gas means a gas containing two or more effective components, or a gas which is an inactive component but whose content exceeds the prescribed limits
Gas safety tips:
1. From the perspective of safety, the feasibility of standard gas mixing must be studied before the preparation of standard gas. In particular, the explosive limit of each component gas should be considered. When preparing the standard gas composed of combustible gas and hydrogen (or oxygen), attention should be paid to whether the content of component gas exceeds the explosive limit. Otherwise, an explosion may occur in the process of preparation.
2, before preparing the standard gas, it should also consider whether chemical reaction (such as oxidation, corrosion, adsorption, etc.) occurs between the component gas and the material used in the cylinder and valve, so as to ensure the stability of the standard gas. According to the compatibility of component gas and packaging container material, different material cylinders and valves are selected to store standard gas.
Shandong Hongsheng Pressure Vessel Co., Ltd. is willing to be your long-term partner and chief cylinder safety officer, and jointly escort your cylinder safety.
The properties of the gas mixture depend on the type and composition of the constituent gases. The composition of the gas mixture can be expressed in three ways.
① Volumetric composition: the ratio of component volume of the gas to the total volume of the mixed gas is expressed by RI.
The so-called partial volume refers to the volume of the component gas at the temperature and total pressure of the mixture.
(2) Mass composition: the ratio of the mass of the constituent gas to the total mass of the mixed gas is represented by WI.
③ Molar composition: a mole is the quantitative unit of a substance. If the number of basic units (which may be atoms, molecules, ions, electrons, or other particles) contained in a system is equal to 0.012 kg of carbon-12 atoms, the amount of matter in the system is 1 mole. The ratio of the number of moles of the constituent gases to the total number of moles of the mixture is x sub I.
