Specifications:

Metal-free columns

• L-column Metal-free column is packed with the high performance materials (like L-column2 or L-column3) into a metal free column hardware.
• L-column3 Metal-free column is made from the combination of a PEEK lined stainless steel tube and PEEK frits.
• L-column2 Metal-free column is made from the combination of a glass lined stainless steel tube and non-metallic frits.
• L-column3 and L-column2 metal free columns are improved the peak shape, carryover and S/N in the analysis of proteins, peptides and coordination compounds.

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 are 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.

• Improving chemical stability, so that usable within the range of pH 1 to pH 12.
• Low adsorptivity is at the top level for various analytes.
• Improvement of separation or peak shape, since the pH of an eluent is flexibly selectable
• A 100% aqueous eluent can be stably analyzed.

L-column series is the column for reversed-phase high-performance liquid chromatography (RP-HPLC) that enabled separation only by hydrophobic interaction because of inhibition of the secondary interaction with residual silanol groups and metal impurities.
