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
analytical technique, can be analyzed on an Rtx®-5 Amine column. The tubing sur-
face is chemically altered to reduce tailing of basic compounds, eliminating the need
for column priming. An Rtx®-5 Amine column is ideal for analyzing a wide variety of
basic compounds, but breakthrough technology also allows the analysis of neutral
compounds, adsorptive compounds with oxygen groups susceptible to hydrogen bond-
ing, or even weakly acidic compounds such as phenols. Every Rtx®-5 Amine column
is tested to ensure that it exceeds the requirements for analyzing ppm levels of amines,
without priming, and to ensure low bleed at maximum operating temperature.
