產品概述
Rt®-Alumina BOND/Na2SO4 Columns （fused silica PLOT）
（Na2SO4 deactivation）
Guaranteed Reproducibility
Each Rt®-Alumina BOND column is tested with a hydrocarbon test mix to ensure proper phase thickness and selectivity. 1,3-Butadiene is used to calculate k （capacity factor）, which is a measure of phase thickness. Selectivity is measured using retention indices for propadiene and methyl acetylene. The resolution of trans-2-butene and 1-butene is also verified. To measure coating efficiency, plates per meter are checked using 1,3-butadiene.
With our new technology, both Na2SO4 and KCl are available with the Rt®-Alumina BOND columns.

1. Highly selective for C1-C5 hydrocarbons; separates all unsaturated hydrocarbon isomers above ambient temperatures. 2. Reactivity of aluminum oxide stationary phase is minimized so that column response for polar unsaturates, such as dienes, is optimized. Column sensitivity or response ensures a linear and quantitative chromatographic analysis for these compounds. 3. Strong bonding prevents particle generation. The column can be used in valve switching operations, without release of particles that can harm the injection and detection systems. 4. The Rt®-Alumina BOND column is stable up to

Acetylene/propadiene elute after butanes （impurities in acetylene/propadiene）.
Best separation for butene isomers （impurities in butene streams）.
Methyl acetylene elutes after 1,3-butadiene.
Cyclopropane （impurity in propylene） elutes well before propylene.
