ZORBAX Eclipse Plus
◈ Product Information
Eclipse Plus columns provide the ultimate in performance for silica-based columns. Peak shape is excellent for the most challenging basic compounds, improving efficiency and resolution with these sample types. These results are achieved by improvements in the silica manufacturing and bonding technology, which is completely controlled by Agilent. Because of their high level of performance, Eclipse Plus columns are the ideal first choice for method development of all samples. To achieve fast method development and superior productivity, choose a column with high-resolution 1.8 um particles. For standard methods, conventional 5 µm and Rapid Resolution 3.5 um columns are your best choice. With all particle sizes, easy method transfer
Eclipse Plus columns are recommended for initial method development from pH 2-9 and provide high resolution and excellent peak shape of all types of compounds. Like all Eclipse columns Eclipse Plus columns achieve superior performance through extra dense bonding and a precise double-endcapping process. But Eclipse Plus columns also feature enhanced high-performance silica, new endcapping reagents, and a unique bonding process that is optimized for the improved silica.
Eclipse Plus columns are available in C18, C8, and a new C18 bonded phase for the separation of PAH’s (polycyclic aromatic hydrocarbons). Eclipse Plus columns are available in particle sizes ranging from 1.8um to 5um – RRHT to Prep and are a rapidly growing new product family. Rapid Resolution HT (RRHT) 1.8um columns provide the fastest analysis times and the highest resolution in a new wider range of column dimensions supporting high pressure use.
► Point
- Excellent peak shape for basic compounds
- High level of performance—peak shape, efficiency, resolution, and lifetime—with all sample types: acids, bases and neutrals
- Easy, efficient method development
- Superior reproducibility with more rigorous QA/QC testing
- Improved, patented silica manufacturing with start-to-finish product control
- Available in 1.8, 3.5 and 5um particle sizes for all analytical, high resolution, and fast LC analyses
- Available in C18, C8, and a new C18 specifically for PAH separations
► Specification
*Column lifetime will be reduced significantly at pH>7 and temperature>°C. At pH 6-9, highest column stability for all silica based columns is obtained by operating at temperatures<40°C and using lower buffer concentrations in range of 0.01 – 0.02M, especially with phosphate and carbonate buffers.
