Rtx®-5Amine
(low-polarityphase; Crossbond®5%diphenyl /95%dimethyl polysiloxane)
• Application-specific columns for amines andother basic compounds, including alkylamines,
diamines, triamines, ethanolamines, andnitrogen-containingheterocyclics.
• Stable to315°C.
Activebasiccompounds thatpreviously requiredderivatizationoranotheranalytical techniquecanbe
analyzed on the Rtx®-5Amine column. The tubing surface is chemically altered to reduce tailing of
basic compounds, eliminating theneed for columnpriming.Breakthrough technologyalsoallows the
analysis of neutral compounds, adsorptive compounds with oxygen groups susceptible to hydrogen
bonding, and evenmildly acidic compounds such as phenols.
Thorough testingof eachRtx®-5Amine column ensures that every column exceeds the requirements
for analyzingppm levelsof amines,without priming.The temperatureprogram/bleedprofile for each
column ismeasured to ensure lowbleed atmaximumoperating temperature.Rtx®-5Amine columns
are bonded and canbe rejuvenatedby solvent rinsing.

(low-polarityphase, Crossbond®5%diphenyl /95%dimethyl polysiloxane)
• General purpose columns for semivolatiles, phenols, amines, residual solvents, drugs of abuse, pesti-
cides, PCB congeners or (e.g.)Aroclor®mixes, solvent impurities.
• Temperature range: -60°C to330/350°C (bleed tested temperature/maximumoperating temperature).
• Lowbleed - improved signal tonoise ratio, for better sensitivity andmass spectral integrity.
• Equivalent toUSPG27phase.
