gc columns

Next Generation GC PLOT Columns• New bonding process minimizes particle release, reducing columnblockage and protecting instrument parts.• More consistent flow means stable retention times in Deans andrelated flow switching techniques.• Outstanding peak symmetry improves impurity analysis for gases,solvents, and hydrocarbons.GC COLUMNS | PLOT COLUMNSPLOT Column SelectionQuick Reference ChartPLOT ColumnRt-Alumina BOND/MXT-Alumina BOND(Na2SO4 deactivation)Rt-Alumina BOND(KCl deactivation)Rt-Alumina BOND(CFC deactivation)Rt-Msieve 5A/MXT-Msieve 5ARt-Q-BOND/MXT-Q-BONDRt-QS-BONDRt-S-BOND/MXT-S-BONDRt-U-BONDApplicationC1–C5 hydrocarbons.Purity analysis of ethylene, propylene, butenes, butadiene . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 108C1-C10 hydrocarbons, C1-C5 isomers.Purity analysis of ethylene, propylene, butene, butadiene. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 108Multi-halogenated alkanes, C1-C-5 range.CFCs (chlorofluorocarbons) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 108Permanent gas analysis (polarity between Q-BOND and S-BOND).He, Ne, Ar, O2, N2, Xe, Rn, SF6, and CH4, C2H6, CO . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 109Nonpolar porous polymer.High retention for solvents, alcohols, polar volatiles, CO2, sulfur, and ppm water in solvents . . . . . . . . . . . . . . . .110Intermediate polarity porous polymer.Neutral solvents, ketones, esters, hydrocarbons, and baseline separation of ethane, ethene, acetylene . . . . . . . 110Intermediate polarity porous polymer.Light gases in ethylene and propylene, ketones, esters, hydrocarbons . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 110Polar porous polymer.More retention for polar compounds . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 110PagePLOT Column Phase Cross-Reference: Similar SelectivityRestek Porous Layer Agilent/J&W Supelco Alltech Varian/Chrompack QuadrexRt-Alumina BOND/Na2SO4 Aluminum oxide GS-Alumina Alumina-Sulfate AT-Alumina CP-Al2O3/NA2SO4 ——MXT-Alumina BONDRt-Alumina BOND/KCl Aluminum oxide GC-Alumina KCl Alumina-Chloride —— CP-Al2O3/KCl ——HP PLOT Al203Rt-Alumina BOND/CFCunique productRt-Msieve 5A Molecular sieve 5A HP PLOT Molesieve Molsieve 5A PLOT AT-Molesieve CP-Molesieve 5A PLT-5AMXT-Msieve 5ARt-Q-BOND DVB porous polymer HP PLOT Q Supel-Q-PLOT AT-Q CP-PoraPlot Q, ——MXT-Q-BONDPoraBond QRt-QS-BOND Intermediate polarity GS-Q —— —— —— ——porous polymerRt-S-BOND DVB vinylpyridine —— —— —— CP-PoraPlot S ——MXT-S-BONDpolymerRt-U-BOND DVB ethyleneglycol- HP-PLOT U —— —— CP-PoraPlot U, ——dimethylacrylate polymerCP-PoraBond U800-356-1688 or 814-353-1300 www.restek.com 105Website : www.chromtech.net.au E-mail : info@chromtech.net.au TelNo : 03 9762 2034 . . . in AUSTRALIA Mar 2011
