气相色谱仪测定ppb级痕量CO2
1962年K.Porter和D.H.Volman提出转化法,将样品中的CO经镍触媒催化加氢转化成CH_4,用气相色谱仪氢火焰离子化检测器(FID)检测。目前这种方法已被广泛用来测定微量CO和CO_2。
ppb级痕量CO2含量测定，即使采用FID+甲烷转化炉也很难准确测定，况且甲烷转化炉还存在转化率和镍触酶的失效问题，为了解决这一难题，滕州市浩瀚色谱仪器技术服务有限公司，，以科学发展为指导，，，色谱工程研究所，分析与测试中心3个科研单位，经过大量实验，研发出灵敏度气相色谱仪测定ppb级痕量CO2，CO2含量可以检测到0.2ppm以下，测量数据准确。

Determination of ppb level trace CO2 by ultra-high sensitivity gas chromatograph
In 1962, K. Porter and D. H. Volman proposed a conversion method, in which CO in the sample was converted into CH 4 by catalytic hydrogenation of nickel catalyst, and detected by a gas chromatograph with a flame ionization detector (FID). At present, this method has been widely used to determine trace amounts of CO and CO_2.
It is difficult to determine the content of trace CO2 at the ppb level even if the FID+ methane reformer is used. Moreover, the methane reformer still has the conversion rate and the failure of nickel catalase. To solve this problem, Tengzhou Haohan Chromatography Instrument has limited technical services The company is advancing with the times and guided by scientific development. Under the leadership of manager Wang Xiaoying, relying on three scientific research units, Xiangying Institute of Analytical Technology, Chromatographic Engineering Institute, and Analysis and Testing Center, after a large number of experiments, they have developed a super high Sensitivity gas chromatograph measures ppb level trace CO2, CO2 content can be detected below 0.2ppm, the measurement data is accurate and reliable.
