岛津玻璃球填充柱测定药典CO2
岛津玻璃球填充柱测定药典CO2 详细信息:
Hydrocarbon is taken as the test gas, and a gas with a methane content of 0.0020% (with nitrogen as a diluent) is used as a control gas, and gas chromatography (General Rule 0521) is used to test the column with glass spheres as a filler ( 4mm × 0.8m, 80 mesh); column temperature is 110 ° C; inlet temperature is 110 ° C; detector is flame ionization detector, temperature is 120 ° C. The test gas and the control gas are measured and injected into the chromatograph. The peak area measured at the purification temperature of 360 ° C is the corresponding blank value; the gas for the test sample and the control gas are taken, injected into the chromatograph, and the peak area is measured and reduced. The peak area after the corresponding blank value is the corrected peak area. According to the external standard method, the hydrocarbon content (in terms of methane) should not exceed 0.0020%.

质量保证:
采用优质的不锈钢管、玻璃管和色谱填料制作各种GX填充色谱柱
如需要用不锈钢过滤网作为柱两端堵头,请在订货时注明
若采用柱上进样,柱入口前端将留有6CM 的空间,
为防止色谱填料流出,柱两端均用硅烷化玻璃棉封堵
若采用阀进样或非柱上进样的色谱柱,其柱入口处被填满
可提供多种型号气相色谱仪所用玻璃柱构型
2mm内径玻璃柱管的入口处均设有斜面以利进样
每根色谱柱均经过充分老化和严格质量评价测试
注意事项
感谢您购买浩瀚生产的色谱柱.
浩瀚提供的每一根色谱柱均经过老化,为保证您获得的分析分离效果,请在使用前再老化1-2小时。老化时,应先通载气10min左右,待柱内空气置换干净后,再用程序升温升至Z高使用温度老化。
为避免检测器被污染,老化时请不要将色谱柱和检测器相连。
当柱箱温度高于室温时,载气中少量氧会损坏色谱柱内的固定相,载气必须采用脱氧管进一步脱氧(建议所用载气中氧气含量不要超过1PPm)
安装色谱柱时,产品Pai号应面向操作者,左侧为色谱柱的进样口(或见标识)。
拆卸色谱柱时,先将柱温降至室温,然后再关载气。
