Abstract
A gas dividing and blending system including a gas divider for generating a mid-span gas for more than one analyzer at the same time so that the analyzers can run their mid-span checks at the same time. A mid-span gas is generated using the span gases for the analyzers. If desired, a separate diluent gas may also be mixed with the span gases to generate a mid-span gas. Once a mid-span gas is generated, it is then simultaneously delivered to each analyzer which uses the mid-span gas to perform its mid-span gas check at the same time as the other analyzers.
