haohan气相色谱载气氮专用脱氧管柱HH-Deoxygenation tube

惰性气体(如氮气、氩气、氮气等)的脱氧方法目前采用两种方式一种是配氢法，另一种是采用固体脱氧剂的脱氧法。配氢法是在惰性气体中加入过量的氢，使氢与氧反应生成水，从而达到脱氧的目的。这种方法的缺点是氢气的运输、存储需要格外小心，且配入量需精密仪器检测，而且，由于生成的水较多，为达到低露点，需要增加增压装置或增加吸附剂的量，导致设备投资增加。此外，过量配氢还会使惰性气体中含有较多的氢。第二种方法的固体脱氧剂采用的是碳载形脱氧剂或金属脱氧剂，金属脱氧剂需用氢气频繁再生，而碳载型脱氧剂由于属消耗型，故价格及维持费用较高。上述两种方法的共同缺点是，只能适于小气量或较低氧含量的气体脱氧。

在气相色谱电子捕获检测器E CD使用氮气做载气时，因氧对基线造成干扰，因此必须脱除载气中的氧，以保证足够高的灵敏度。

The deoxidation method of inert gas (such as nitrogen, argon, nitrogen, etc.) currently adopts two methods: one is hydrogen distribution method, and the other is deoxidation method using solid deoxidizer. The hydrogen distribution method is to add excess hydrogen to the inert gas to make the hydrogen react with oxygen to form water, so as to achieve the purpose of deoxygenation. The disadvantage of this method is that the transportation and storage of hydrogen requires extra care, and the dosage needs to be detected by precision instruments. Moreover, due to the large amount of water generated, in order to achieve a low dew point, it is necessary to increase the pressure booster or increase the amount of adsorbent. lead to increased investment in equipment. In addition, excessive hydrogen distribution will make the inert gas contain more hydrogen. The solid deoxidizer used in the second method is a carbon-supported deoxidizer or a metal deoxidizer. The metal deoxidizer needs to be frequently regenerated with hydrogen, while the carbon-supported deoxidizer is expendable, so the price and maintenance cost are high. The common disadvantage of the above two methods is that they are only suitable for deoxidizing gases with small gas quantities or low oxygen content.

When nitrogen is used as the carrier gas in the GC electron capture detector E CD, the oxygen in the carrier gas must be removed to ensure a sufficiently high sensitivity because oxygen interferes with the baseline.

The HH-Deoxygenation tube deoxygenation column produced by Haohan Chromatography has large column capacity and good deoxygenation effect, and is widely used in gas chromatography.
