Metal columns area better alternative than fused silica, and the MXT®-1HT SimDist columns are thelowest bleed, highest efficiency columns available, outperforming other metalcolumns for critical method parameters.ID df temp. limits 5-Meter 10-Meter0.53mm 0.10µm -60 to 430/450°C 701120.20µm -60 to 430/450°C 701150.21µm -60 to 430/450°C 701180.88µm -60 to 400/430°C 70131 701341.00µm -60 to 380/400°C 701301.20µm -60 to 380/400°C 701192.65µm -60 to 360/400°C 701325.00µm -60 to 360/400°C 70133Low bleed, high efficiency MXT®-1HT SimDist columns outperform competitors (ASTM D6352 conditions).Restek, 5m x 0.53mm x 0.2μmC50/C52R = 2.89Lower bleed means:• Longer column lifetime.• More stable calibrations.• Accurate boiling point determinations.RESTEK ADVANTAGE:Longer column lifetime andmore accurate data!Bleed = 14pA0 10 20 30 40Time (min)GC_PC1149Agilent/ J&W, 5m x 0.53mm x 0.15μmC50/C52R = 1.81Bleed = 61pAHigher efficiency means:• Greater resolution; analyze more samplesbefore method criteria are reached.• Assured method performance.RESTEK ADVANTAGE:Run more samples within methodspecifications!0 10 20 30 40Time (min)GC_PC1150Varian, 5m x 0.53mm x 0.17μmC50/C52R = 1.84Bleed = 57pA0 10 20 30 40Time (min)GC_PC115178 www.restek.comWebsite : www.chromtech.net.au E-mail : info@chromtech.net.au TelNo : 03 9762 2034 . . . in AUSTRALIA Mar 2011
