GC COLUMNS | CAPILLARY COLUMNSFused Silica Guard/Retention Gap Columnsalso availableBase-deactivated inlet linersSee page 213.Base-Deactivated Guard/Retention Gap Columns (fused silica)• Tested with a basic amine test mix.• Excellent inertness for basic compounds.• Recommended for use with Rtx®-5 Amine, Rtx®-35 Amine, Rtx®-Volatile Amine,and Stabilwax®-DB capillary columns.• Batch test chromatogram included.• Maximum temperature: 315 °C.Chemists using guard columns in the analyses of basic compounds frequently observepeak tailing and low recovery. This happens because conventionally deactivated tubingsurfaces can be adsorptive to basic compounds. Restek offers base-deactivated guardcolumns, as well as base-deactivated inlet liners, for completely inert sample pathways.Nominal ID Nominal OD 5-Meter 5-Meter/6-pk.0.25mm 0.37 ± 0.04mm 10000 10000-6000.32mm 0.45 ± 0.04mm 10001 10001-6000.53mm 0.69 ± 0.05mm 10002 10002-600did you know?We test our guard columns/transfer lineswith a comprehensive test mix to ensurehigh inertness.also availableMetal MXT® Guard ColumnsRugged, flexible, Siltek® treated stainless steeltubing; inertness comparable to fused silicatubing. See page 114.Hydroguard® Water-Resistant Guard/Retention Gap Columns/TransferLines (fused silica)• Extend analytical column lifetime by preventing degradation from harsh“steam-cleaning” water injections.• Tested with a comprehensive test mix, to ensure high inertness.• Maximum temperature: 325 °C.When transfer lines from purge & trap systems, air monitoring equipment, or otherinstruments carry condensed water vapor, deactivated column tubing quickly becomesactive because of the creation of free silanol groups. These silanol groups adsorb activeoxygenated compounds, such as alcohols and diols.Restek chemists have addressed this concern and found a solution—the Hydroguard®deactivation process. A unique deactivation chemistry creates a high-density surfacethat is not readily attacked by aggressive hydrolysis. The high-density surface coverageof the Hydroguard® deactivation layer effectively prevents water vapor from reachingthe fused silica surface beneath. Use Hydroguard® tubing for connecting GCs to:• Headspace analyzers.• Air analysis equipment and concentrator units.Nominal ID Nominal OD 5-Meter 5-Meter/6-pk. 10-Meter 30-Meter* 60-Meter*†0.05mm 0.363 ± 0.012mm 100750.10mm 0.363 ± 0.012mm 100760.15mm 0.363 ± 0.012mm 100770.18mm 0.37 ± 0.04mm 100780.25mm 0.37 ± 0.04mm 10079 10079-600 10082 10085 100880.32mm 0.45 ± 0.04mm 10080 10080-600 10083 10086 100890.53mm 0.69 ± 0.05mm 10081 10081-600 10084 10087 10090*30- and 60-meter lengths are banded in 5-meter sections.†Recommendation: Cut 60m guard columns into shorter lengths. Using full length may cause peak distortion.34 www.restek.comWebsite : www.chromtech.net.au E-mail : info@chromtech.net.au TelNo : 03 9762 2034 . . . in AUSTRALIA Mar 2011
GC COLUMNS | CAPILLARY COLUMNSFused Silica Guard/Retention Gap ColumnsInnovative Integra-Guard® Columns• No leaks for a more robust method.• No column connections for easier, faster maintenance.• No peak distortions due to connector dead volume and thermal capacity.For analysts who find it inconvenient to make a leak-free connection between the guardcolumn and the analytical column, we offer Integra-Guard® columns. These innovativecolumns incorporate both guard column and analytical column in a continuous lengthof tubing, eliminating the connection and all connection-associated problems! Theguard column section is marked separately from the analytical column, using hightemperaturestring.A wide variety of our Integra-Guard® capillary columns are listed below. The Integra-Guard® column is so economical that we challenge you to compare our price againstthat of a conventional connection, even if you assemble it yourself. If you are currentlyusing a guard column, or are considering using one, call today and ask about Integra-Guard® columns.restek innovation!Integra-Guard® Columns: guard columnsWITHOUT connections—protecting youranalytical column has never been this easy!similar productsDuraGuard, EZ-Guard, GuardianIntegra-Guard® built-in guard columnDescription qty. cat.# priceRtx-130m, 0.25mm ID, 0.25µm Rtx-1 w/5m Integra-Guard Column ea. 10123-12430m, 0.53mm ID, 1.00µm Rtx-1 w/5m Integra-Guard Column ea. 10155-12630m, 0.53mm ID, 5.00µm Rtx-1 w/5m Integra-Guard Column ea. 10179-126Rtx-530m, 0.25mm ID, 0.25µm Rtx-5 w/5m Integra-Guard Column ea. 10223-12430m, 0.25mm ID, 0.25µm Rtx-5 w/10m Integra-Guard Column ea. 10223-12730m, 0.25mm ID, 1.00µm Rtx-5 w/5m Integra-Guard Column ea. 10253-12430m, 0.32mm ID, 0.25µm Rtx-5 w/5m Integra-Guard Column ea. 10224-12530m, 0.32mm ID, 1.00µm Rtx-5 w/5m Integra-Guard Column ea. 10254-12530m, 0.53mm ID, 5.00µm Rtx-5 w/5m Integra-Guard Column ea. 10279-12660m, 0.32mm ID, 0.25µm Rtx-5 w/5m Integra-Guard Column ea. 10227-125Rtx-5MS15m, 0.25mm ID, 0.25µm Rtx-5MS w/5m Integra-Guard Column ea. 12620-12415m, 0.25mm ID, 0.50µm Rtx-5MS w/10m Integra-Guard Column ea. 12635-12730m, 0.25mm ID, 0.10µm Rtx-5MS w/5m Integra-Guard Column ea. 12608-12430m, 0.25mm ID, 0.25µm Rtx-5MS w/5m Integra-Guard Column ea. 12623-12430m, 0.25mm ID, 0.25µm Rtx-5MS w/10m Integra-Guard Column ea. 12623-12730m, 0.25mm ID, 0.50µm Rtx-5MS w/5m Integra-Guard Column ea. 12638-12430m, 0.25mm ID, 0.50µm Rtx-5MS w/10m Integra-Guard Column ea. 12638-12730m, 0.32mm ID, 0.25µm Rtx-5MS w/5m Integra-Guard Column ea. 12624-12530m, 0.32mm ID, 1.00µm Rtx-5MS w/5m Integra-Guard Column ea. 12654-125Rxi-5Sil MS15m, 0.25mm ID, 0.25µm Rxi-5Sil MS w/10m Integra-Guard Column ea. 13620-12730m, 0.25mm ID, 0.25µm Rxi-5Sil MS w/5m Integra-Guard Column ea. 13623-12430m, 0.25mm ID, 0.25µm Rxi-5Sil MS w/10m Integra-Guard Column ea. 13623-12715m, 0.25mm ID, 0.50µm Rxi-5Sil MS w/5m Integra-Guard Column ea. 13635-12430m, 0.25mm ID, 0.50µm Rxi-5Sil MS w/5m Integra-Guard Column ea. 13638-12430m, 0.25mm ID, 0.50µm Rxi-5Sil MS w/10m Integra-Guard Column ea. 13638-12730m, 0.32mm ID, 0.50µm Rxi-5Sil MS w/5m Integra-Guard Column ea. 13639-12530m, 0.32mm ID, 1.00µm Rxi-5Sil MS w/5m Integra-Guard Column ea. 13654-125Rtx-62430m, 0.25mm ID, 1.40µm Rtx-624 w/5m Integra-Guard Column ea. 10968-12430m, 0.32mm ID, 1.80µm Rtx-624 w/5m Integra-Guard Column ea. 10970-12530m, 0.53mm ID, 3.00µm Rtx-624 w/5m Integra-Guard Column ea. 10971-126Rtx-130130m, 0.53mm ID, 3.00µm Rtx-1301 w/5m Integra-Guard Column ea. 16085-126Rtx-170130m, 0.25mm ID, 0.25µm Rtx-1701 w/5m Integra-Guard Column ea. 12023-124Stabilwax30m, 0.25mm ID, 0.25µm Stabilwax w/5m Integra-Guard Column ea. 10623-12430m, 0.32mm ID, 1.00µm Stabilwax w/5m Integra-Guard Column ea. 10654-12530m, 0.53mm ID, 1.00µm Stabilwax w/5m Integra-Guard Column ea. 10655-126String indicates where theanalytical column begins.Tag indicates guard column end.Integra-Guard® columns are available for allphases listed, for columns with 0.25, 0.32 or0.53mm ID.
