Sulfur Traces and Permanent Gas Analysis in Beverage Grade Carbon Dioxide
Analyzer Description
Configuration:
SCD, PDHID, cryogenic cooling, onboard vaporizer, 3-valves, 3-capillary columns
Sample type:
Beverage grade carbon dioxide, gas or liquid
Compounds Separated:
- argon
- nitrogen
- carbon monoxide
- methane
- hydrogen sulfide
- carbonyl sulfide
- sulfur dioxide
- ethyl mercaptan
- dimethyl sulfide
- carbon disulfide
- isopropyl mercaptan
- ethyl methyl mercaptan
- butyl mercaptan
- isobutyl mercaptan
- diethyl mercaptan
- dimethyl disulfide
- 2-methylthiophene
- 3-methylthiophene
- diethyl disulfide
- phenyl mercaptan
- total sulfur by summation
Any additional sulfurs up to a boiling point of 240°C will be detected if present in the sample.
Lower detection limits:
2 ppm for permanent gases
0.10 ppm for sulfur dioxide
0.03 ppm for sulfurs and mercaptans
Methods met:
ISBT 4.0, ISBT 10.1, ISBT 14.0
Typical Chromatogram
Key Features and Benefits
- Oxygen will be detected but will not be quantified. For accurate oxygen analysis an external oxygen sensor is required.
- Fused silica lined tubing protects sample integrity.
- Internally purged diaphragm valves ensure no air contamination and the lowest detection limits possible.
- On-board vaporizer converts liquid carbon dioxide to gas phase prior to injection for more repeatable analysis.
- Can be configured for both liquid and gas sample analysis.
