Agilent Eclipse XDB Cartridge Columns Data Sheet
This document provides a data sheet for Agilent Eclipse XDB-C8 and -C18 microparticulate packings. These columns utilize eXtra-Dense Bonding (XDB) technology on ultra-pure silica supports to protect against dissolution at intermediate pH levels, making them suitable for separating acidic, basic, and highly polar compounds via reversed-phase liquid chromatography.

Questions answered in these manuals
What are the recommended wash volumes for different column lengths?
Typical wash volumes are 12.5 mL for a 75 mm length, 25 mL for a 150 mm length, and 41 mL for a 250-mm length.
What solvent is used to ship ZORBAX and Eclipse columns?
The shipping solvent is water/acetonitrile or water/methanol.
What is the range of concentrations tested for linearity?
The study covers a wide range of approximately 150 ng to 5,000 ng.
What is the relative standard deviation (RSD) for retention times?
The RSD for retention times was less than 0.07% for all six linearity levels.
What is the total run time for the analysis including equilibration?
The total run time, which includes re-equilibration, can be limited to 14 minutes.
What wavelength was used for the variable wavelength detector?
The VWD was set to detect at a wavelength of 254 nm.
