Product Description

Total Sulfur in CO2 Applications

The BevAlert Model 8900 provides a total sulfur measurement for sulfur compounds in Carbon Dioxide. The measurement includes organic sulfides, Sulfur Dioxide, Carbonyl Sulfide, and Hydrogen Sulfide.

The instrument is utilized by Specialty Gas Manufacturers and the Food and Beverage Industry to monitor sulfur compounds in CO2 used in carbonated beverages.

The sample entering the GC is passed through a proprietary catalyst where sulfur containing compounds are reduced to Hydrogen Sulfide. The

APPLICATIONS

Measuring total sulfur content in beverage grade carbon dioxide.
