SH-Rt columns are porous layer open tubular (PLOT) GC columns. These columns are ideal for efficient and reproducible analysis of volatile compounds.
SH-Rt-Alumina BOND/Na2SO4: for butene isomers, cyclopropane elutes before propylene, methyl acetylene elutes before 1,3-butadiene
SH-Rt-Alumina BOND/KCl: low moisture sensitivity, acetylene elutes before n-butane, methyl acetylene elutes before 1,3-butadiene
SH-Rt-Msieve 5A: separation of permanent gases, sharp and symmetrical peaks for argon, oxygen and carbon monoxide
SH-Rt-Q-BOND: for analysis of C1 to C3 hydrocarbons and isomers as well as alkanes up to C12, analysis of oxygenated compounds and solvents
SH-Rt-U-BOND: for polar and nonpolar compounds, ideal for trace analysis of H2S, COS and mercaptans in hydrocarbon streams
