一般常用的定碳仪对于合碳量大于0.05％的测定是适用的。对于含碳量低于0.05％的测定时,由于含碳量低,产生的CO_2气体很少,因此在定碳仪量气管中测出的CO_2气体误差较大,因此一般测出的含碳量偏差很大。当含碳量小于0.005％的物质就无法使用一般定碳仪来测定。因此一般低含量碳的测定都采用电导等微量定碳仪来测定。由于一般厂矿实验室还不可能普遍地具有这种定
Commonly used carbon analyzer for the carbon content of more than 0.05% of the determination is applicable. For the determination of carbon content less than 0.05%, due to the low carbon content, the production of CO 2 gas is very small, so the carbon dioxide measured in the carbon dioxide measuring tube error is larger, so the measured carbon content Deviation is great. When the carbon content of less than 0.005% of the material can not be used to determine the general carbon analyzer. Therefore, the determination of low carbon content are generally used to determine the conductivity of trace carbon analyzer. Due to the general factory mines laboratory is not yet possible with this set
