New Agilent ZORBAX Eclipse Plus columns provide the ultimate in performance for silicabased
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. If you need to achieve fast method development and
superior productivity, then choose a column with high-resolution 1.8 µm particles. For
standard methods, conventional 5 µm and Rapid Resolution 3.5 µm columns are your best
choice. With all particle sizes, easy method transfer is possible.
With more rigorous QA and QC testing, column lot-to-lot reproducibility is also improved,
resulting in long-term reliable results for all analyses.

*Column lifetime will be reduced significantly at pH > 7 and temperature > 40°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.
