Standard gas, also called standard reference gas mixture or gaseity standard material, is a big type of standard materials. Its components' concentration value has three greatest characteristics of stability, uniformity and accuracy. Standard gases are very importent and indispensable in many areas such as inspect and calibrate instruments, evaluate analysis methods, ascertain materials characteristics, examine operator's technical level, producing process quality control and so on.
