其中氧含量≤30ul/L

其中水分含量≤30ul/L

以上是食品添加剂中对水分和氧含量的规定，检测需要两款仪器，操作复杂，费时费力，不环保，效率低下，使用受限，无法满足工业大规模生产检测的需要。

浩瀚色谱（山东）应用技术开发有限公司，与时俱进，研发气相色谱法一次进样同时测定食品添加剂二氧化碳中微量水分和氧的含量，面积外标法定量，结果准确可靠。

According to the different properties of CO2 and its impurities, physical and chemical methods are used to gradually remove the impurities. It is verified by analysis that the high-purity carbon dioxide produced by this process can reach 5N, which can be popularized and applied.

Wherein oxygen content≤30ul/L

Wherein moisture content≤30ul/L

The above are the regulations on moisture and oxygen content in food additives. The detection requires two instruments, which are complicated to operate, time-consuming and laborious, not environmentally friendly, low in efficiency, and limited in use, which cannot meet the needs of industrial large-scale production testing.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd., keeping pace with the times, developed a gas chromatography method to simultaneously determine the content of trace moisture and oxygen in food additives carbon dioxide in one injection, and the area external standard method for quantification, and the results were accurate and reliable.

Haohan chromatography is unique in the determination of O2 and H2O in food additives. Welcome to consult and negotiate.
