Gas is widely used in process control and quality control of various industries. With years of experience and rich expertise, Shanglan Energy provides efficient and convenient solutions for high purity gas, standard gas and special gas.
Standard gas for measurement and control of air separation products
It is used for the detection and index control of impurities in air separation products such as nitrogen, argon, oxygen, high purity hydrogen, helium, etc. It is generally 2-component or multi-component standard gas.
