Unlike other gases, the requirements for the cylinder containing the electronic mixture of gases are very strict, otherwise, even the mixture of gases with high accuracy and stability can not be used.

First of all, the cylinder geometry of mixing gas such as volume, diameter, bottle height to meet the user's requirements. In the field of semiconductors, gas cylinders are usually placed in the cylinder cabinet for use. After the size of the cylinder cabinet and the connected valve parts are determined, the size of the cylinder cannot be arbitrary. For different types of mixture in the cylinder color code, warning signs and other aspects of foreign extremely detailed standards, such as the United States OF CGA, the European Union of ISO, etc., our country is still in the understanding and improvement in this area.
