PAC analyzers provide the food and beverage industry a better way to sniff out potential sulfur contamination before product hits the shelves and threatens consumer loyalty.
Sulfur, total and aromatic hydrocarbons, oxygen and moisture have been implicated in carbon dioxide contamination. Likewise, nitrogen levels in CO2 are known to adversely affect food and beverage production. Sulfur in CO2 can kill catalysts in some processes and ruin product in the food and beverage industry. Traditionally, sulfur has been detected using a simple tape, stain tube or sniff test. In most cases, this has been sufficient to reject a bad lot of carbon dioxide. In recent years, however, more and more beverage products have been pulled from consumer shelves due to sulfur contamination in carbon dioxide. Carbonyl sulfide and other sulfur species are missed by tape and stain tube tests as they are often specific for only certain sulfur compounds. Millions of dollars worth of beverages have been pulled as a result of this contamination, not to mention local consumer loyalty losses when such events have occurred. Responsibility for these events often falls on the shoulders of the carbon dioxide supplier or distributor. PAC offers a unique turn-key system used in the production process for the quality assurance of CO2. The TQACO2 is a complete analyzer package with a single operating data system which provides on-line analysis of sulfur, nitrogen, total aromatic hydrocarbons, aromatics, oxygen and/or moisture that allows gas suppliers and bulk CO2 users to generate their own load report to show compliance with specifications.
