L-column C8

CERI L-column2 ODS Micro Guard Cartridge Trap Column, 5μm, 5mm Length x 0.3mm ID - 3 per pack

For PEEK-sleeved Micro / Nano Columns

Product Number: 652453

Specifications:

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.

L-column C8 is end-capped using the same advanced method used for L-column ODS. L-column C8 is most suitable for reducing the analysis time of hydrophobic compounds and conserving solvent.

USP

L7: Octyl silane chemically bonded to totally or superficially porous silica particles, 1.5 to 10 μm in diameter, or a monolithic silica rod.

Trap column

In proteomic analysis using LC/MS/MS, the trap column is indispensable for increasing the injection volume. This trap column retains the target constituents firmly and its media has little irreversible adsorption of the target constituents. Therefore, the actual loss of target constituents is negligible. In the range of 20 - 1000 ng for the insulin B chain, a linear relationship is obtained between the injection volume and the peak area.

A small dead volume, low-adsorption property and high retention ability that traps target constituents are required effectively in a trap column. L-column trap column does not decrease the theoretical plate number because of its very small dead volume. Not only that, because it is a cartridge-type trap column, it is more economical.
