GC COLUMNS | APPLICATION-SPECIFIC COLUMNS
Specially Deactivated
Rtx®-35 Amine Columns (fused silica)
(midpolarity phase; Crossbond® 35% diphenyl/65% dimethyl polysiloxane)
• Application-specific columns for amines and other basic compounds, including
alkylamines, diamines, triamines, ethanolamines, and nitrogen-containing
heterocyclics.
• Stable to 220 °C.
Active basic compounds that otherwise require derivatization, or an alternative ana-
lytical technique, can be analyzed on an Rtx®-35 Amine column. The tubing surface
is chemically altered to reduce tailing of basic compounds, eliminating the need for
column priming. An Rtx®-35 Amine column is ideal for analyzing a wide variety of
basic compounds, but breakthrough technology also allows the analysis of neutral
compounds and adsorptive compounds with oxygen groups susceptible to hydrogen
bonding. Every Rtx®-35 Amine column is tested to ensure that it meets the require-
ments for analyzing ppm levels of amines, without priming, and to ensure low bleed at
maximum operating temperature.
