Rtx®-35Amine
(fused silica)
(Crossbond
®
35% diphenyl/65% dimethyl polysiloxane)
Rtx®-35Amine
(mid-polarityphase; Crossbond®35%diphenyl /65%dimethylpolysiloxane)
• Application-specific columns for amines andother basic compounds, including alkylamines,
diamines, triamines, ethanolamines, andnitrogen-containingheterocyclics.
• Stable to310°C.
Active basic compounds that otherwise require derivatization can be analyzed on anRtx®-35Amine
column.The tubing surface is chemicallyaltered to reduce tailingof basiccompounds, eliminating the
need for columnpriming.AnRtx-35®Amine column is ideal for awide varietyof basic compounds,
but also is suitable for neutral compounds, adsorptive compoundswithoxygen groups susceptible to
hydrogenbonding,or evenweaklyacidic compounds suchasphenols.EveryRtx®-5Amine column is
tested to ensure that it exceeds the requirements for analyzingppm levelsof amines,without priming,
and to ensure lowbleed atmaximumoperating temperature.
