Rxi-1ms are non-polar general-purpose columns for a wide range of different applications.
Rxi-1HT are non-polar columns with a 40% longer lifetime due to a special designed fused silica tubing for high molecular weight hydrocarbons.
Rxi-5ms are low polar general-purpose columns for semi volatiles, phenols, amines, residual solvents, drugs of abuse, pesticides, PCB congeners and solvent impurities.
Rxi-5HT are low-polar columns with a 40% longer lifetime due to a special designed fused silica tubing for high temperature applications such as mineral oil.
Rxi-XLB have a proprietary low polar phase for general-purpose applications such as pesticides, PCB congeners and PAHs.
Rxi-5Sil MS are low polar columns for general purpose applications.
Rxi-35Sil MS is a mid-polar phase with a special selectivity for substituted polar compounds such as drugs, pesticides, herbicides, PCBs, phenols, etc.
Rxi-17 are mid-polar columns for general purpose applications like pesticides, herbicides, rosin acids, phthalate esters, triglycerides and sterols.
Rxi-17Sil MS columns have a mid-polar phase for active environmental compounds such as PAHs.
Rxi-PAH have a mid-polar proprietary phase that is ideally suited for EFSA PAH4 analysis.
Rxi-624Sil MS are mid-polar, low-bleed and high-thermal stable columns for volatile organics and residual solvents and is a good choice for USP<467>.
Rxi-1301Sil MS are mid-polar phases with an stabilized cyano phase selectivity for terpenes, glycol ethers, fusel alcohols and other polar compounds.
Rxi-SVOCms is a proprietary phase with 5%-phenyl excellent performance for semivolatiles in complex matrices.
Rxi-LAO have a proprietary mid-polar phase especially designed for linear alpha olefin (LAO) impurity analysis.
