Rt-XLSulfur columns are optimized for low ppb-level sulfur analysis!
Rt-XLSulfur型填充柱是分析ppb级硫化物的*选择.
Sulfur analyses are traditionally performed using Teflon tubing to improve column inertness. Unfortunay, Teflon? tubing is gas permeable, difficult to pack with high efficiency, prone to shrinkage, and has poor thermal stability. Analyses of ppbv levels of sulfur compounds are now possible with the Rt?-XLSulfur column. The packing material for Rt?-XLSulfur columns is extensively deactivated for analysis of low ppbv levels of hydrogen sulfide and methyl mercaptan. It is then treated to achieve effective separation of hydrocarbons from sulfur compounds. The interior wall and the end-fittings of the Rt?-XLSulfur column are Sulfinert? treated, making the column as inert as Teflon?. The extra care taken with this column ensures more accurate analyses of sulfur compounds.一般情况下分析含硫成份的化合物都要使用特氟隆(或聚四氟乙烯)柱管以改进基化学惰性。但是Teflon管线具有气体渗漏的问题,又有热胀冷缩的问题,因此难以保证有很好的柱效与重现性,再者这种柱管的热稳定性比较差。现在分析ppbV级含硫混合物可以使用特殊处理过的硫钝化柱管(Rt-sulfur)来分析分离。Rt-XLSuflur型硫钝化柱管具有对硫化物的*惰性。并且Rt-XLSuflur的填充材料在分析ppbV级硫化物和甲基硫醇时惰性。可以将烃从其它含硫成份中分离出来。Rt-XLSuflur柱的内壁经过的Sulfinert工艺处理,其惰性与Teflon管相同。这种柱子在硫化物分析中是非常成功的。
