haohan药典2020版四部二氧化碳分析玻璃球柱4mm*0.8m

碳氢化合物　取本品作为供试品；取甲烷含量为0.0020%的气体（以氮气为稀释剂）作为对照气体，照气相色谱法（通则0521）试验，用玻璃球为填料的色谱柱（0.8m×4mm，80目）；柱温为110℃；进样口温度为110℃；检测器温度为120℃。量取供试品气体与对照气体，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；量取供试品气体与对照气体，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。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（山东）应用技术开发有限公司，与时俱进，依据药典标准生产玻璃球柱测定二氧化碳中碳氢化合物，柱效高，分离好，在安捷伦，岛津，赛默飞，瓦里安，布鲁克，PE等进口仪器及国产仪器上安装使用，效果良好，受到用户的好评。

Hydrocarbon Take this product as the test sample; Take the gas with 0.0020% methane content (nitrogen as diluent) as the reference gas, test according to the gas chromatography method (General Rule 0521), and use the glass ball as the packing column (0.8m × 4mm, 80 meshes); The column temperature is 110 ℃; The injection port temperature is 110 ℃; The detector temperature is 120 ℃. Measure the test gas and reference gas, inject them into the gas chromatograph, and the peak area measured at the purification temperature of 360 ℃ is the corresponding blank value; Measure the test sample gas and the reference gas, inject them into the gas chromatograph, and measure the peak area. The peak area after subtracting the corresponding blank value is the corrected peak area. The hydrocarbon content (calculated by methane) shall not exceed 0.0020% according to the corrected peak area calculated by external standard method.



Haohan Chromatographic (Shandong) Application Technology Development Co., Ltd. keeps pace with the times. It produces glass ball columns to determine hydrocarbons in carbon dioxide according to the pharmacopoeia standards. The column efficiency is high and the separation is good. It is installed and used on Agilent, Shimadzu, Thermophile, Varian, Brooke, PE and other imported instruments and national instruments. The effect is good and the users praise it.
