In addition, they are perceived tobe more rugged and reliable than otherbonded phases. C18 bonded phasesdepend mainly on hydrophobicinteractions (and occasionally shapeselectivity) to achieve satisfactoryseparations.

<strong>ACE</strong> ® <strong>Excel</strong> TM <strong>Ultra</strong> <strong>Robust</strong> <strong>UHPLC</strong> <strong>Columns</strong>Column-to-column reproducibility and ultrarobust, reliable performance<strong>Excel</strong>lent ReproducibilityColumn-to-column reproducibilityis affected by a number of factorsincluding the production of the silicastationary phase support, themanufacture of the silane stationaryphase, the bonding of the stationaryphase to the support and thepacking of the stationary phase intothe column. The more tightly eachstage of the column manufacturingprocess is controlled, the better thequality of the resultant column will be.<strong>ACE</strong> columns are subjected to extensivecontrols at each stage of themanufacturing process, to ensurethat <strong>ACE</strong> columns produce reliable,predictable high performanceseparations from column-to-columnand batch-to-batch.Figure 4: <strong>ACE</strong> ® <strong>Excel</strong> TM <strong>UHPLC</strong> columns are exceptionally durableApplication #1506% Initial Efficiency120100806040200Prototype 2µm C18 Column(column manufactured withoutHSC packing technology)Number of Injections<strong>ACE</strong> <strong>Excel</strong> 2 C18 <strong>UHPLC</strong> Column(column manufactured with HSCpacking technology)0 500 1000 1500 2000Fast Gradient Conditions:Column Dimensions: 100 x 2.1 mm Flow Rate: 0.73 ml/min P max= 1,000 bar (15,000psi)Mobile Phase: A = 0.1% formic acid in H 2O B = 0.1% formic acid in MeOHGradient: 20% to 90%B in 6 minutes, 1 minute hold90% to 20%B in 1 minute, 2 minutes re-equilibration holdHSC TM High Stability <strong>Columns</strong>All <strong>ACE</strong> <strong>Excel</strong> <strong>UHPLC</strong> columns aremanufactured using a proprietaryHSC (High Stability Column) packingtechnology, which results in ultra robustcolumns.<strong>ACE</strong> <strong>Excel</strong> 2 C18 – StartNot only are <strong>ACE</strong> <strong>Excel</strong> columns packedexceptionally well, they incorporate aninlet frit design that reduces the risk ofplugging.0 1 2 3 4 5 6 7MinutesIt is still re<strong>com</strong>mended that you filtersamples and mobile phases as youwould with any <strong>UHPLC</strong> column, but<strong>ACE</strong> <strong>Excel</strong> columns provide the samelevels of durability and lifetime that youwould expect from HPLC columns.<strong>ACE</strong> <strong>Excel</strong> 2 C18 – After 2,000 fast gradient cycles0 1 2 3 4 5 6 7MinutesEfficiency and peakshape unchangedFigure 4 illustrates the excellent columnlifetime provided by an <strong>ACE</strong> <strong>Excel</strong>column under searching fast gradient<strong>UHPLC</strong> conditions.A 100 x 2.1mm <strong>ACE</strong> <strong>Excel</strong> 2µm C18 <strong>UHPLC</strong> column manufacturedusing the proprietary HSC (High Stability Column) packingtechnology was subjected to a gradient cycle incorporating a P maxof1,000 bar (15,000psi).

In particular, thehydrophobic binding interaction appears to offer no selectivity forseparating peaks 1, 2 and 3 and offers only poor resolution of peaks 4, 5and 6.The <strong>ACE</strong> <strong>Excel</strong> C18-PFP provides the additional selectivity needed toseparate the co-eluting analytes under these conditions. It is believedthat this additional selectivity is provided by a powerful <strong>com</strong>binationof the strong π-π and dipole-dipole interactions, coupled with thestrong shape selectivity and hydrophobic character offered by theunique C18-PFP phase.468<strong>ACE</strong> <strong>Excel</strong> <strong>Ultra</strong> <strong>Robust</strong> <strong>UHPLC</strong> <strong>Columns</strong>www.ace-hplc.<strong>com</strong>

Alternatively,a leak at the inlet fitting connection may be observed.<strong>ACE</strong> <strong>UHPLC</strong> Column Connectors are reuseable and enable<strong>UHPLC</strong> columns to be correctly installed every time. Theirunique design ensures that they maintain pressure ratingwith repeated use, yet do not permanently swage onto theinlet tubing. To maximise the lifetime of the fitting, the useof an <strong>ACE</strong> Torque Wrench (p/n EXL-TW) is required.Standard <strong>ACE</strong> HPLC PEEK finger-tight connectors (p/n <strong>ACE</strong>-FT, pressure rated to 350bar/5000psi) may be used at theoutlet end of the <strong>UHPLC</strong> column, where pressure demandsare lower but a correct connection remains important.<strong>ACE</strong> <strong>Excel</strong> 2µm C18 <strong>Columns</strong>ColumnDiameter2.1mm3.0mm4.6mm<strong>ACE</strong> <strong>Excel</strong> 2µm C18-AR <strong>Columns</strong>ColumnDiameter2.1mm3.0mm4.6mm<strong>ACE</strong> <strong>Excel</strong> 2µm C18-PFP <strong>Columns</strong>ColumnDiameter2.1mm3.0mm4.6mmColumn Length20mm 30mm 35mm 50mm 75mm 100mm 125mm 150mmEXL-101-0202UEXL-101-0203UEXL-101-0246UColumn Length20mm 30mm 35mm 50mm 75mm 100mm 125mm 150mmEXL-109-0202UEXL-109-0203UEXL-109-0246UColumn Length20mm 30mm 35mm 50mm 75mm 100mm 125mm 150mmEXL-1010-0202UEXL-1010-0203UEXL-1010-0246UEXL-101-0302UEXL-101-0303UEXL-101-0346UEXL-109-0302UEXL-109-0303UEXL-109-0346UEXL-1010-0302UEXL-1010-0303UEXL-1010-0346UEXL-101-3502UEXL-101-3503UEXL-101-3546UEXL-109-3502UEXL-109-3503UEXL-109-3546UEXL-1010-3502UEXL-1010-3503UEXL-1010-3546UEXL-101-0502UEXL-101-0503UEXL-101-0546UEXL-109-0502UEXL-109-0503UEXL-109-0546UEXL-1010-0502UEXL-1010-0503UEXL-1010-0546UEXL-101-7502UEXL-101-7503UEXL-101-7546UEXL-109-7502UEXL-109-7503UEXL-109-7546UEXL-1010-7502UEXL-1010-7503UEXL-1010-7546UEXL-101-1002UEXL-101-1003UEXL-101-1046UEXL-109-1002UEXL-109-1003UEXL-109-1046UEXL-1010-1002UEXL-1010-1003UEXL-1010-1046UEXL-101-1202UEXL-101-1203UEXL-101-1246UEXL-109-1202UEXL-109-1203UEXL-109-1246UEXL-1010-1202UEXL-1010-1203UEXL-1010-1246UEXL-101-1502UEXL-101-1503UEXL-101-1546UEXL-109-1502UEXL-109-1503UEXL-109-1546UEXL-1010-1502UEXL-1010-1503UEXL-1010-1546U<strong>UHPLC</strong>Connector1, 2, 3EXL-CC1, 2, 3EXL-CC1, 2, 3EXL-CC<strong>UHPLC</strong>Connector1, 2, 3EXL-CC1, 2, 3EXL-CC1, 2, 3EXL-CC<strong>UHPLC</strong>Connector1, 2, 3EXL-CC1, 2, 3EXL-CC1, 2, 3EXL-CC1 Also available as a 10pk p/n EXL-CC102 Torque wrench (p/n EXL-TW) is required3Starter kit available (p/n EXL-CCSK) containing 4x EXL-CC plus 1x EXL-TWwww.ace-hplc.<strong>com</strong><strong>ACE</strong> <strong>Excel</strong> <strong>Ultra</strong> <strong>Robust</strong> <strong>UHPLC</strong> <strong>Columns</strong>9
