CERI L-column3 C8
Features of the L-column3:
- Improves chemical stability so that it is usable within the range of pH 1 to pH 12
- Low absorptivity is at the top level for various analytes
- Improvement of separation or peak shape as the pH of an eluent is flexibly selectable
- A 100% aqueous eluent can be stably analyzed. (Perfect chemical stable silica)
Perfectly stable end-capping bonded phase C18, C8 PCS silica 2 Silica-based columns with the many advantages of high-separation efficiency and mechanical strength are currently used for reversed-phase chromatography. Conversely, the pH range of usable eluent is limited because exposure to the alkaline solution is easily dissolved silica. L-column3 is an all-around column wherein the chemical stability (acid and alkaline resistance) of the packing material is dramatically improved by using a newly-developed and highly alkaline resistant PCS silica (perfectly chemically stable silica) and perfectly stable end-capping with performance much higher than that of L-column2. L-column3 offers the possibility of improved analysis.

Description
L-column3
Silica-based columns with the many advantages of high separation efficiency and mechanical strength are currently used most generally for the columns for reversed-phase chromatography. On the other hand, the pH range of usable eluent is limited because exposure to the alkaline solution is easily dissolved silica.
L-column3 is an all-around column where the chemical stability (acid and alkaline resistance) of the packing materials is dramatically improved by using newly developed and highly alkaline resistant PCS silica (perfect chemical stable silica) and perfectly stable end-capping with performance much higher than that of L-column2.
L-column3 proposes the possibility of a new analysis.
