Abstract
A system and method for determining impurities in a beverage grade gas such as CO2 or N2 relies on a coupling of FTIR analysis and UV fluorescence detection. Conversion of reduced sulphur present in some impurities to SO2 can be conducted using a furnace. In some cases, CO2% also is determined.
Claims20
A system for measuring impurities in a beverage grade gas, the system comprising:
- a spectrometer including a gas cell for detecting an absorbance spectrum of the gas in the gas cell, wherein the gas cell is configured for pressures higher than two atmospheres;
- and
- a sulfur analyzer including an oxidizing furnace for converting reduced sulfur present in the gas to SO2 and a UV fluorescence apparatus for determining total SO2 amounts in the sample.
A method for analyzing a beverage grade gas, the method comprising:
- directing a first portion of a gas sample to a gas cell;
- measuring impurities present in the gas cell with a spectrometer at pressures higher than two atmospheres;
- directing a second portion of the gas sample to an oxidizing furnace;
- converting reduced sulfur present in the second portion to SO2;
- and
- measuring a total SO2 in the second portion of the gas sample.
