C18 Attached Silica Monolith Microcolumns Made in Stainless Steel Tubing and Their Application in Analysis of Flavonoids in Green Tea Extracts

摘要

Recently,the monolith columns have raised a lot of interest in liquid chromatography.The whole stationary phase of the monolith column is one body with numerous multiple porous channels,thus it does not need any frit since the whole stationary phase functions as a frit.A monolith column is prepared by in situ polymerization or condensation of organic or inorganic monomers inside the column tubing and,if necessary,the surface is functionalized.
