What is analytical gas?

Analytical gas is a specialized gas in the analysis of experiments. Or it can be said that analytical gas is a special gas used in the field of experimental analysis.
Depending on the purpose and requirements of the experiment, people use different gases or gases or mixtures of gases.

• If it is a single gas, purity is required (For example: purity 5.0: 99.999%; 6.0: 99.9999%…).
• If it is a mixed gas mixture, it is necessary to ensure the correct ratio of the required gas components to be selected.

Impurities mixed in the gas cylinder (such as moisture, dust particles, impurities, etc.) can cause erroneous analysis results.
More seriously, impurities can damage the analytical instruments used. Therefore, the current analytical gas has very high requirements for purity as well as accuracy.
