Food additives - Determination of trace amounts of carbon monoxide and carbon dioxide in nitrogen
Food additives - Determination of trace amounts of carbon monoxide and carbon dioxide in nitrogen Details:

Name: Portable Methane Reformer
Model: HH-CH4-GC
Application: Determination of trace carbon monoxide and carbon dioxide

Suitable for: Agilent 4890. 5890, 6890, 7890, 7820, 8860, 8890 Gas Chromatograph

GB 29202-2012 National Food Safety Standard Food Additives Nitrogen

The standard stipulates that the volume concentration of carbon monoxide is less than or equal to 0.001 or 10ppm

The standard stipulates that the volume concentration of carbon dioxide is less than or equal to 0.003 or 30ppm

The national standard stipulates the use of zirconia detectors. However, the reality is that zirconia detectors are a chemical detector with poor linearity and repeatability, and are prone to inverted peaks. The technology needs to be improved. Now the standard zirconia detector drafted by high-purity gas is replaced by helium ion or plasma detector, which is the trend of analytical instrument development.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd., keeping pace with the times, has taken a new approach and used the mature methane reformer gas chromatography method to determine the content of trace carbon monoxide and carbon dioxide in food-grade N2, and the effect is very satisfactory.
