ZORBAX Extend HPLC Columns |
 |
|
Extend-C18 columns incorporate a unique patented bidentate silane, combined with a double-endcapping process that protects the silica from dissolution at high pH - up to pH 11.5. columns are best applied for separations of compounds that are either (1) basic and have little or no retention at low or intermediate pHs, (2) more stable or more soluble at high pH, or (3) basic and show poor peak shape at low or intermediate pH.
- High efficiency and long life at high pH – up to pH 11.5
- Unique bidentate bonding and double endcapping provides high pH stability
- More efficiency and better peak shape than polymer-based columns
- Improve retention, resolution and peak shape of basic compounds
- High sensitivity for LC/MS separations of peptides

| ZORBAX Extend Rapid Resolution HPLC Columns |
- Reduce analysis time and solvent usage and increase sample throughput
- High efficiency in short and ultra-short column lengths
- Available in analytical (4.6 mm) and narrow-bore (2.1 mm) ID
- Comparable lifetime to 5 μm columns

Agilent ZORBAX Rapid Resolution columns, with a 3.5 μm particle size, reduce analysis time and increase sample throughput for any application when compared to 5 μm columns. Rapid Resolution columns are available from 15-150 mm, in 1-4.6 mm IDs, so the best configurations are available for high throughput, LC/MS, combinatorial chemistry and rapid analytical applications. Rapid Resolution 3.5 μm particles have superior mechanical strength, so every column has an extremely stable packed bed and provides a comparable lifetime to 5 μm columns.

| ZORBAX Extend Rapid Resolution High Throughput HPLC Columns |
- New high pressure (600 bar) columns for ultra high speed or maximum resolution analyses with Rapid Resolution HT columns packed with totally porous, 1.8 μm packings
- Carefully engineered particles deliver maximum resolution at 25% less pressure than other sub 2-micron materials
- Reduce analysis time by up to 95%
- Develop HPLC methods more quickly
- Securely transfer conventional methods with over 80 RRHT column choices
- Analyze complex samples on shorter columns faster and maximize peak capacity
- Perform faster analyses and use less solvent
- Short (50 mm long and less) column can be used on some conventional LCs

ZORBAX Rapid Resolution HT (1.8 μm) columns use a totally porous, 1.8 μm particle to provide maximum resolution in fast, ultra-fast and high resolution analyses. You can reduce analysis time by up to 95% in comparison to 250 mm length columns. The small particle size provides double the efficiency of a 3.5 μm column in the same column length providing the highest efficiency and resolution possible. This permits the analysis of complex samples on shorter column with the highest resolution and peak capacity. The 1.8 μm Rapid Resolution HT columns take high-speed, high-resolution HPLC to a new level. The 600 bar columns can be used with the new Agilent 1200 Rapid Resolution LC up to this high pressure limit. In addition, the shorter columns can be used on many other LC's, including the Agilent 1100 by using the RRHT-1100 conversion kits to maximize performance. |
