名稱：便攜式甲烷轉(zhuǎn)化爐
型號：HH-CH4-GC
應(yīng)用：微量一氧化碳和二氧化碳的測定

適合于：安捷倫4890. 5890, 6890, 7890, 7820, 8860, 8890氣相色譜儀上

GB 29202-2012 食品安全國家標(biāo)準(zhǔn) 食品添加劑 氮氣

標(biāo)準(zhǔn)中規(guī)定一氧化碳體積濃度≤0.001即10ppm

標(biāo)準(zhǔn)中規(guī)定二氧化碳體積濃度≤0.003即30ppm

國標(biāo)規(guī)定采用氧化鋯檢測器，然而現(xiàn)實是氧化鋯檢測器是一種化學(xué)檢測器，線性和重復(fù)性差，且容易出倒峰，技術(shù)還有待完善改進?，F(xiàn)在高純氣體起草的標(biāo)準(zhǔn)氧化鋯檢測器被氦離子或者等離子檢測器所取代，這是分析儀器發(fā)展的趨勢。

浩瀚色譜（山東）應(yīng)用技術(shù)開發(fā)有限公司，，另辟蹊徑，采用技術(shù)成熟的甲烷轉(zhuǎn)化爐氣相色譜法測定食品級N2中微量的一氧化碳，二氧化碳的含量，效果非常滿意。

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.
