GC Columns
SH-Alumina BOND The reactivity of the aluminum oxide stationary phase is minimized to improve column response for polar unsaturates, such as dienes, and the column's sensitivity (or response) ensures linear and quantitative chromatographic analysis for these compounds.
Highly selective for C1–C5 hydrocarbons
Separate all saturated and unsaturated hydrocarbon isomers above ambient temperatures.
SH-Alumina BOND/Na 2 SO 4 Na 2 SO 4 deactivation Acetylene and propadiene elute after butanes. Best separation for butene isomers (impurities in butene streams). Methyl acetylene elutes after 1,3-butadiene. Cyclopropane (impurity in propylene) elutes well before propylene. Similar phases: GS-ALUMINA, CP-Al2O3/Na2SO4, Alumina sulfate PLOT

SH-Alumina BOND/KCL KCl deactivation Lowest polarity alumina column in Shimadzu PLOT columns. Low moisture sensitivity reduces the need for frequent regeneration. Acetylene elutes before n-butane. Methyl acetylene (impurity in 1,3-butadiene) elutes before 1,3-butadiene. Similar phases: GS-Alumina KCI, HP-PLOT Al2O3 KCl, CP-Al2O3/KCl, Alumina chloride PLOT
