What Is the Difference between Binary, Ternary and Multi-element Standard Gases?

Standard gas refers to the gas that conforms to the ideal gas state equation (PV=nRT) under standard conditions (normal pressure and temperature, i.e. 1 atm and 273.15K). Standard gas is a term in the gas industry. Standard substances are measurement standards with uniform concentration, good stability and accurate value. They have the basic functions of reproducing, preserving and transferring values. They are used in the fields of physical, chemical, biological and engineering measurement to calibrate measuring instruments and measurement processes, 

Standard gas refers to the gas that conforms to the ideal gas state equation (PV=nRT) under standard conditions (normal pressure and temperature, i.e. 1 atm and 273.15K). Standard gas is a term in the gas industry. Standard substances are measurement standards with uniform concentration, good stability and accurate value. They have the basic functions of reproducing, preserving and transferring values. They are used in the fields of physical, chemical, biological and engineering measurement to calibrate measuring instruments and measurement processes, evaluate the accuracy of measurement methods and the detection capabilities of testing laboratories, determine the characteristic values of materials or products, and conduct value arbitration. Standard gases are divided into binary, ternary and multi-element standard gases.

The difference between binary, ternary and multi-component standard gases lies mainly in the different quantities of components they contain.

Binary standard gas is a standard gas composed of two gas components, such as a mixture of carbon dioxide and nitrogen.

Binary standard gas is usually used in specific applications, such as environmental monitoring, food safety, etc.

Ternary standard gas is a standard gas composed of three gas components, such as a mixture of oxygen, nitrogen and carbon dioxide. Ternary standard gas is usually used in combustion analysis, biomedicine and other application fields.

Multi-component standard gas is a standard gas composed of more than three gas components, such as air standard gas, which contains multiple gas components such as oxygen, nitrogen, carbon dioxide, etc. Multi-component standard gas is usually used in a wide range of application fields, such as industrial production, scientific research, etc.

In addition to the difference in the number of components, there are also certain differences in the preparation and quality control of binary, ternary and multi-component standard gases. Since multi-component standard gases containing more components are more complicated in preparation and quality control, their preparation and management requirements are also more stringent. When using standard gases, it is necessary to select the appropriate standard gas type according to the specific application.
