4Å分子筛填充柱应用于岛津GC-2014详细信息：



4Å分子筛水含量分布，结果表明，脱附温度为200～230℃时，在非真空气氛脱附时，有效残留水含量为4%～5%，有效脱附水含量达到了24%～25%，吸水率为83%～87%；在真空气氛下脱附时，有效残留水含量为1%～2%，有效脱附水含量达到了27%～28%，吸水率为93%～97%。为了使有效残留水含量低于2%，较佳脱附再生条件为真空气氛、脱附温度不低于200℃。采用差热失重法可以估算分子筛在非真空气氛下的有效脱水含量与有效残余水含量。真空脱附后样品吸水速率大于非真空脱附的吸水速率。

Application of 4 Å molecular sieve packed column in Shimadzu GC-2014

Application of 4 Å molecular sieve packed column in Shimadzu GC-2014 detailed information:





The distribution of water content in 4 Å molecular sieves shows that when the desorption temperature is between 200 and 230 ℃, the effective residual water content is 4% to 5%, the effective desorption water content reaches 24% to 25%, and the water absorption rate is 83% to 87% under non vacuum atmosphere desorption; When desorbed under vacuum atmosphere, the effective residual water content is 1% to 2%, the effective desorbed water content reaches 27% to 28%, and the water absorption rate is 93% to 97%. In order to reduce the effective residual water content below 2%, the optimal conditions for desorption regeneration are vacuum atmosphere and desorption temperature not less than 200 ℃. The differential thermal gravimetric method can be used to estimate the effective dehydration content and effective residual water content of molecular sieves under non vacuum atmosphere. The water absorption rate of the sample after vacuum desorption is greater than that of non vacuum desorption.
