Servomex has been granted a multi-year contract to provide its Xentra 4100 Gas Purity Analyzer to Praxair of Tonawanda, N.Y.
The Xentra analyzer, which measures trace levels of carbon dioxide, comes equipped with a patented gas filter correlation infrared bench. The primary application of the product will be the monitoring of very low levels of carbon dioxide dissolved in liquid oxygen inside the main condensers of cryogenic air separation plants. If the carbon becomes too concentrated it will solidify.
