碳氢化合物

1.照气相色谱法(通则0521)测定供试品气体取本品,即得对照品气体取甲烷含量为0.0020%的气体(以氮气为稀释剂)。

2.色谱条件用玻璃球为填料的色谱柱(4mm×0.8m,80目);柱温为110℃;进样口温度为110℃;检测器为火焰离子化检测器,温度为120℃。

3.测定法

精密量取供试品气体与对照品气体,分别注入气相色谱仪,在净化温度为360℃时测得的峰面积为相应空白值;精密量取供试品气体与对照品气体,分别注入气相色谱仪,测定峰面积,减去相应空白值后的峰面积为校正峰面积限度按外标法以校正峰面积计算,含碳氢化合物(以甲烷计)不得过0.0020%。

浩瀚色谱研发生产的玻璃球柱，柱效高，分离好，峰型对称，结果满意。被国内两佰多家制药企业采用，受到好评。

提供供应：甲烷标气；净化装置，气相色谱仪，减压阀等配套产品。

Carbon dioxide in Chinese Pharmacopoeia 2020 edition of hydrocarbons Details:

Hydrocarbon

1. According to gas chromatography (general rule 0521) to determine the test sample gas to take this product, that is, the reference sample gas is 0.0020% methane content gas (with nitrogen as the diluent).

2. Chromatographic conditions use a chromatographic column (4mm×0.8m, 80 mesh) filled with glass balls; the column temperature is 110℃; the temperature of the injection port is 110℃; the detector is a flame ionization detector, and the temperature is 120℃.

3. Determination method

Precisely measure the test gas and reference gas and inject them into the gas chromatograph respectively. The peak area measured when the purification temperature is 360°C is the corresponding blank value; precisely measure the test gas and reference gas and inject them into the gas phase. The chromatograph measures the peak area, and the peak area after subtracting the corresponding blank value is the calibrated peak area. The limit is calculated based on the calibrated peak area by the external standard method, and the hydrocarbon content (calculated as methane) shall not exceed 0.0020%.

The glass spherical column developed and produced by Haohan Chromatography has high column efficiency, good separation, symmetrical peak shape, and satisfactory results. It has been adopted by more than 200 domestic pharmaceutical companies and has been well received.

Provide supply: methane standard gas; purification device, gas chromatograph, pressure reducing valve and other ancillary products.
