Rtx®-Volatile Amine Columns

(fused silica)

• Unique selectivity for baseline resolution of all volatile amines.

• Excellent inertness assures accuracy and sensitivity for volatile amines, including

free ammonia.

• Highly robust phase withstands repeated water injections, resulting in longer

column lifetime.

• High temperature stability (290 °C) ensures elution of amines up to C16 and allows

contaminants to be removed by “baking out” the column.

The Rtx®-Volatile Amine column was designed specifically for analyzing volatile amines

in difficult matrices, such as water. The unique base deactivation creates an exception-

ally inert surface for these sensitive compounds, resulting in highly symmetrical peaks,

which allow low detection limits. The stable bonded phase yields a column that is not

only retentive and highly selective for these compounds but is also very robust and able

to withstand repeated water injections. Comparisons made by customers performing

routine volatile amine applications have shown the Rtx®-Volatile Amine column out-

performs other amine-specific columns, especially for peak shape and lifetime. Each

Rtx®-Volatile Amine column is held to stringent quality specifications and tested with

a specially designed test mix that includes basic compounds to ensure exceptional

inertness, reliability, and reproducibility. These qualities assure consistent performance

and make the Rtx®-Volatile Amine column the best choice for volatile amines analysis.
