Rtx®-5 Amine Columns
(fused silica)
(low polarity phase; Crossbond® 5% diphenyl/95% dimethyl polysiloxane)
• Application-specific columns for amines and other basic compounds,
including alkylamines, diamines, triamines, ethanolamines, and nitrogen-containing
heterocyclics.
• Stable to 315 °C.
Active basic compounds that otherwise require derivatization, or an alternative analyt
ical technique, can be analyzed on an Rtx®-5 Amine column. The tubing surface i
chemically altered to reduce tailing of basic compounds, eliminating the need fo
column priming. An Rtx®-5 Amine column is ideal for analyzing a wide variety of basi
compounds, but breakthrough technology also allows the analysis of neutral com
pounds, adsorptive compounds with oxygen groups susceptible to hydrogen bonding
or even weakly acidic compounds such as phenols. Every Rtx®-5 Amine column is test
ed to ensure that it exceeds the requirements for analyzing ppm levels of amines
without priming, and to ensure low bleed at maximum operating temperature.
