GC COLUMNS | APPLICATION-SPECIFIC COLUMNSChiral CompoundsfreeliteratureA Guide to theAnalysis of ChiralCompounds by GCDownload your freecopy fromwww.restek.comlit. cat.# 59889Enantiomers AnalysisCyclodextrin Columns for Analyzing Many Chiral CompoundsBy adding β or γ cyclodextrin to our bonded Rtx®-1701 stationary phase, we greatlyenhance overall utility and column lifetime for our chiral columns, compared tocolumns that have pure cyclodextrin stationary phases. Separations of more than onehundred chiral compounds have been achieved using our unique DEX columns, andour columns continue to demonstrate stability after hundreds of temperature programcycles.Rt®-βDEXm Columns (fused silica)(permethylated beta cyclodextrin doped into 14% cyanopropylphenyl/86% dimethyl polysiloxane)Uses: General purpose chiral phase with many published applications.ID df temp. limits 30-Meter0.25mm 0.25µm 40 to 230°C 131000.32mm 0.25µm 40 to 230°C 13101please noteApplication-specific chiral column kits areavailable! See www.restek.comtech tipChiral selectivity improves significantly byrealizing lower elution temperatures.This can be achieved by:• Faster linear velocities (80 cm/sec.) withhydrogen carrier gas.• Slower temperature ramp rates (1–2 °C/min.).• Appropriate minimum operatingtemperature (40 or 60 °C).• On-column concentrations of 50 ng or less.freeliteratureGrape FlavorAnalysis, Using anRt®-γDEXsa GCColumnlit. cat.# 59553GC Analysis of ChiralFlavor Compounds inApple Juices, UsingRt®-βDEXsm andRt®-βDEXse Columnslit. cat.# 59546Download your freecopies fromwww.restek.comRt®-βDEXsm Columns (fused silica)(2,3-di-O-methyl-6-O-tert-butyl dimethylsilyl beta cyclodextrin doped into 14%cyanopropylphenyl/86% dimethyl polysiloxane)Uses: Excellent column for most chiral compounds in essential oils.ID df temp. limits 30-Meter0.25mm 0.25µm 40 to 230°C 131050.32mm 0.25µm 40 to 230°C 13104Rt®-βDEXse Columns (fused silica)(2,3-di-O-ethyl-6-O-tert-butyl dimethylsilyl beta cyclodextrin doped into 14%cyanopropylphenyl/86% dimethyl polysiloxane)Uses: Similar in performance to Rt-βDEXsm but provides better resolution for limonene, linalool, linalylacetate, ethyl-2-methylbutyrate, 2,3-butane diol, and styrene oxides.ID df temp. limits 30-Meter0.25mm 0.25µm 40 to 230°C 131070.32mm 0.25µm 40 to 230°C 13106Rt®-βDEXsp Columns (fused silica)(2,3-di-O-propyl-6-O-tert-butyl dimethylsilyl beta cyclodextrin doped into 14%cyanopropylphenyl/86% dimethyl polysiloxane)Uses: Often useful in dual-column configurations, with the Rt-βDEXsm column, for complex enantiomericseparations.ID df temp. limits 30-Meter0.25mm 0.25µm 40 to 230°C 131110.32mm 0.25µm 40 to 230°C 13110Rt®-βDEXsa Columns (fused silica)(2,3-di-acetoxy-6-O-tert-butyl dimethylsilyl beta cyclodextrin doped into 14%cyanopropylphenyl/86% dimethyl polysiloxane)Uses: Unique selectivity for esters, lactones, and other fruit flavor components.ID df temp. limits 30-Meter0.25mm 0.25µm 40 to 230°C 131090.32mm 0.25µm 40 to 230°C 13108Rt®-βDEXcst Columns (fused silica)(Proprietary cyclodextrin material doped into 14% cyanopropylphenyl/86% dimethyl polysiloxane)Uses: Proprietary stationary phase, developed specifically for the fragrance industry.
