Reversed Phase Column for HPLC Made by Chemicals Evaluation and Research Institute (CERI), JAPAN 

Features

An important feature of the L-column series is the end-capping technology. `Since the end-capping process has a great effect on the performance of the column, it is a feature that makes a difference between column manufacturers.
In a general ODS column, silica gel and ODS groups are bonded at one point and the silanol groups on the surface are modified and coated by end-capping treatment; however, if this end-capping is inadequate, silanol groups and metal impurities remaining on the silica surface will interact with the analytical sample and affect the peak shape.

L-column2 can increase the modification density and improve the separation by binding the ODS group by trifunctional substitution.
Furthermore, the advanced end-capping process of the original development is applied. This has made it possible to significantly reduce the effects of residual silanol groups and metal impurities.

Why L-column2 is Selected?

Why is L-coluimn2 chosen?
*L-column 2 has high acid durability. This allows the same column to be used for longer periods of
time, making it more economical.
*The absorptivity of basic and coordinating compounds decreases. This improves the peak shape and is very effective in quantitative and qualitative analysis.
*The reproduction between production batches is good. It is an important factor in quality
control.
*L-column is a pioneer in high-performance columns and CERI has a long history in chemical
analysis.
*Users trust the products and analysis results provided by CERI.

One special characteristic of L-coluimn2 is that by using high-purity porous silica, we are developing variations in particle size and bonding groups.
We can provide columns according to your analysis.
