Rt®-Alumina BOND/MAPD Columns
•Optimized deactivation produces maximum response when analyzing trace levels of acetylene, methyl acetylene, and propadiene. Stable response factors make this column ideal for process-type applications where recalibration must be minimized. High loadability reduces peak tailing and improves separations.

Analysis of Trace Hydrocarbon Impurities in 1,3-Butadiene
Identifying and quantifying trace impurities in 1,3-butadiene is critical in producing high quality synthetic rubber products. Standard analytical methods employ alumina PLOT columns which yield good resolution for low molecular weight hydrocarbons, but suffer from irreproducibility and poor sensitivity for polar hydrocarbons. In this application note, Rt®-Alumina BOND/MAPD PLOT columns were used to separate both common light polar contaminants, including methyl acetylene and propadiene, as well as 4-vinylcyclohexene, which is a high molecular weight impurity that normally requires a second test on an alternative column.
Analysis of Trace Hydrocarbon Impurities in 1,3-Butadiene
In this study trace impurities of 1,3-Butadiene are separated into both common light polar contaminants, including methyl acetylene and propadiene, as well as 4-vinylcy¬clohexene, which is a high molecular weight impurity. By using an extended temperature program 4-vinylcyclohexene, as well as all of the typical low molecular weight impurities, can be analyzed in a single test.
