SYSTEM FOR PRODUCING PRIMARY STANDARD GAS MIXTURES
摘要
<p>Provided is a novel system and apparatus (200) for producing primary standard gas mixtures. The system includes providing a gas permeation device (210) having a constant diffusion rate into a temperature controlled enclosure (220); connecting a supply source (230) of a component to the permeation device (210); routing the component from the gas permeation device (210) to a product container (290) until a desired amount of said component in the product container (290) is reached; and supplying a balance of purified gas to the product container (290) to obtain a known concentration of component in the primary standard gas mixture.</p>
