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。??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(jī)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(dāng)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(jìn)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(qiáng)空間排阻的效果，使毛細(xì)柱惰性更強(qiáng)。
Rxi®-5Sil MS色譜柱+Integra-Guard?保護(hù)柱。色譜柱與保護(hù)柱已經(jīng)預(yù)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.
