Rxi-5Sil ms

Rxi-5Sil ms弱极性固定相，选择性与5% 二苯基/95%二甲基聚硅氧烷接近。Rxi-5Sil ms通用型色谱柱。非常适合多环芳烃类、氯代烃类、邻苯二甲酸酯类、酚类、胺类、氯化杀虫剂、有机磷杀虫剂**、溶剂杂质、烃等化合物的GC/MS分析。

Rxi-5Sil ms温度范围: -60°C - 350°C。

Rxi-5Sil ms相当于USP G27固定相。

Rxi-Sil MS固定相是在聚合物骨架中键合了苯基。这种改进有助于提高色谱柱的热稳定性，减弱柱流失和固定相氧化。并且能增强空间排阻的效果，使毛细柱惰性更强。

Rxi®-5Sil MS色谱柱+Integra-Guard™保护柱。色谱柱与保护柱已经预先连接，因此消除了影响测试结果平行性的人为因素，并且整体通过了全项测试。

low-polarity phase; Crossbond 1,4-bis(dimethylsiloxy)phenylene dimethyl polysiloxane

• Engineered to be a low-bleed GC-MS column.
• Excellent inertness for active compounds.
• General-purpose columns—ideal for GC-MS analysis of semivolatiles, polycyclic aromatic compounds, chlorinated hydrocarbons, phthalates, phenols, amines, organochlorine pesticides, organophosphorus pesticides, drugs, solvent impurities, and hydrocarbons.
• Temperature range: -60 °C to 350 °C.

·         Rxi fused silica capillary GC columns were designed specifically to be the best columns available for exceptional inertness, ultra-low bleed, and reproducible retention and selectivity. In addition to outstanding performance, this combination of column characteristics assures Rxi columns will have long lifetimes. Restek chemists have also developed a stable, reproducible manufacturing process so that Rxi columns will meet your needs every time you install a new column.

·         The Rxi-5Sil MS stationary phase incorporates phenyl groups in the polymer backbone. This improves thermal stability, reduces bleed, and makes the phase less prone to oxidation. Rxi-5Sil MS columns are ideal for GC-MS applications requiring high sensitivity, including use in ion trap systems.
