DM-PLOT Alumina / Na2SO4
DM-PLOT Alumina / Na2SO4
• Butanes (impurities in acetylene / propadiene) elute before acetylene /
propadiene
• Best separation for butene isomers (impurities in butene streams)
• Propylene elutes after cyclopropane (impurity in propylene)
• Similar to GS-Alumina, HP-PLOT S, Alumina Sulfate PLOT, AT-Alumina,
and CP-Al2O3 / Na2SO4 PLOT
