Rxi-5Sil ms弱極性固定相，選擇性與5% 二苯基/95%二甲基聚硅氧烷接近。Rxi-5Sil ms通用型色譜柱。非常適合多環(huán)芳烴類、氯代烴類、鄰苯二甲酸酯類、酚類、胺類、氯化殺蟲劑、有機磷殺蟲劑**、溶劑雜質(zhì)、烴等化合物的GC/MS分析。

Rxi-5Sil ms溫度范圍: -60°C - 350°C。

Rxi-5Sil ms相當于USP G27固定相。

Rxi-Sil MS固定相是在聚合物骨架中鍵合了苯基。這種改進有助于提高色譜柱的熱穩(wěn)定性，減弱柱流失和固定相氧化。并且能增強空間排阻的效果，使毛細柱惰性更強。

Rxi®-5Sil MS色譜柱+Integra-Guard?保護柱。色譜柱與保護柱已經(jīng)預先連接，因此消除了影響測試結(jié)果平行性的人為因素，并且整體通過了全項測試。

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.
