White Papers

Bridge has developed a library of reference material related to emissions and exhaust gas analysis. This is a result of decades of experience manufacturing exhaust gas analyzers, servicing 2 gas, 4 gas and 5 gas analyzers, and calibrating exhaust gas analyzers with certified standard gas meeting BAR-90 and BAR-97 component mixtures.

Gas testing in food packaging modified atmosphere packaging applications has provided Bridge the ability to become an expert resource in industry best practices in terms of O2, CO2 and CO gas measurement in the package headspace. There are a number of white paper reference documents available here related to this expertise.
