Application:

• Measurement of VCAMB in beverage grade carbon dioxide

Analyzer

The BevAlert Model 8900 provides direct measurement of Vinyl Chloride, Acetaldehyde, Methanol, and Benzene (VCAMB) in Carbon Dioxide. The instrument is utilized by Specialty Gas Manufacturers and the Food and Beverage Industry to monitor trace impurities in CO2 used in carbonated beverages. The BevAlert Model 8900 employs a photoionization detector (PID). TheVCAMB in the gas sample are physically seperated using proprietary GC columns. A dual-column configuration with timed backflush to vent is used to strip off moisture and heavier gases. At sample injection, a fixed volume of sample is carried through the pre-cut column. The backflush is timed so that primarily the VCAMB and other similar compounds continue on to the analytical column. Contaminants are then backflushed to vent. Vinyl Chloride, Acetaldehyde, Methanol, and Benzene are separated from potentially interfering components on the analytical column and elute to the detector for analysis.
