HH-CH4-GC便携式甲烷转化炉气相色谱仪 食品添加剂 氮气中微量一氧化碳及二氧化碳测定

名称：便携式甲烷转化炉
型号：HH-CH4-GC
应用：微量一氧化碳和二氧化碳的测定

适合于：安捷伦4890. 5890, 6890, 7890, 7820, 8860, 8890气相色谱仪上

GB 29202-2012 食品安全国家标准 食品添加剂 氮气

标准中规定一氧化碳体积浓度≤0.001即10ppm

标准中规定二氧化碳体积浓度≤0.003即30ppm

国标规定采用氧化锆检测器，然而现实是氧化锆检测器是一种化学检测器，线性和重复性差，且容易出倒峰，技术还有待完善改进。现在高纯气体起草的标准氧化锆检测器被氦离子或者等离子检测器所取代，这是分析仪器发展的趋势。

浩瀚色谱（山东）应用技术开发有限公司，，另辟蹊径，采用技术成熟的甲烷转化炉气相色谱法测定食品级N2中微量的一氧化碳，二氧化碳的含量，效果非常满意。

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.
