XY-Sulfur 硫化物专用填充柱的详细资料

硫化物专用填充柱
硫化物专用填充柱 详细信息：

规格:2M*2MM(ID)*3MM(OD)

型号：XY-Sulfur

应用：硫化物专用柱

玻璃、PTFE 和不锈钢柱现存的不同的问题。玻璃管，在该领域和应用控制上，表现出不够坚固和缺乏耐用性，不同的柱管会导致保留因子的变化。PTFE 管虽然比玻璃柱坚固，但却被三个严重的问题困扰：1) 收缩，柱的冷却导致氧气的返回扩散以及水进入到包装材料中。如果不解决，能导致保留时间的变化高达15
%。2) 氧气和水扩散到管壁，明显降低柱的使用寿命和产生了重现问题。3) 大柱温仅是210度 的限制，造成它不可能快速洗脱高分子量重硫化合物。

滕州市浩瀚色谱仪器技术服务有限公司，研发出XY-Sulfur型硫化物分析填充柱，硫化氢，羰基硫，二氧化硫，二硫化碳得到分离，结果满意。

In general, compounds containing sulfur components are analyzed using a Teflon (or Teflon) column to improve the chemical inertness of the base. However, the Teflon pipeline has the problem of gas leakage and the problem of thermal expansion and contraction, so it is difficult to ensure good column efficiency and reproducibility. Moreover, the thermal stability of the column tube is relatively poor. Analysis of ppbV grade sulfur-containing mixtures can now be analyzed using specially treated sulfur passivated column tubes. The sulfur passivated column tube has excellent inertness to sulfides. Also, its inertness is the same as that of the Teflon tube. This column was very successful in sulfide analysis.
Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. developed a XY-Sulfur type sulfide analysis packed column, hydrogen sulfide, carbonyl sulfide, sulfur dioxide and carbon disulfide were effectively separated, and the results were satisfactory.
