Total sulfur measurement for sulfur compounds in CO2 for food & beverage industry - Food and Beverage
The sample entering the GC is passed through a proprietary catalyst where sulfur containing compounds are reduced to Hydrogen Sulfide. The BevAlert Model 8900 employs a photoionization detector (PID) for detection of the H2S in the reduced sample stream. 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 the H2S elutes to the analytical column. Contaminants are then backflushed to vent. Hydrogen Sulfide is separated from potentially interfering components on the analytical column and elutes to the detector for analysis.
