Agilent ZORBAX Eclipse XDB-C18 HPLC columns are eXtra Densely Bonded (XDB) and double endcapped through a proprietary process to cover as many active silanols as possible. The XDB-C18 phase is an excellent general-purpose column with a slightly higher carbon load than the ZORBAX Eclipse Plus C18 phase. The higher hydrophobicity provides alternative selectivity for lipophilic analytes. Available with fully porous silica in 1.8 µm, 3.5 µm, and 5 µm for use on either UHPLC or HPLC instrumentation.
Features
- General purpose C18 column useful for method development at mid-pH
- Higher hydrophobicity with alternative selectivity for lipophilic analytes
- Long lifetime with eXtra Dense Bonding and double endcapping
- Higher carbon load than Eclipse Plus C18
- Fully porous silica-based columns in 1.8 µm, 3.5 µm, and 5 µm sizes
- Guards extend the lifetime of analytical columns without diminishing performance
- USP L1 classification
- ZORBAX Eclipse XDB reversed phase chemistries also include Eclipse XDB C8, Eclipse XDB-Phenyl, and Eclipse XDB-CN for alternative selectivity
