Development of the collections and the blanket making;

Due to the good permeability,fast mass transfer property,high stability,and the ease of modification,monolithic materials have been widely used in microcolumn separation systems,not only as the stationary phase for capillary electrochromatography(CEC) and microcolumn high performance liquid chromatography(μ-HPLC),but also as the matrix for sample enrichment and enzyme reactor.

A 1-D mathematical model,including the electrical potential distribution equation,the buffer concentration equation,as well as the sample electromigration and diffusion equation,is developed through proper simplifications and assumptions to study the sample stacking process in capillary electrophoresis.

A review for the related studies is presented from several aspects,including sources and formation,environmental effects,sampling,and measurements.

Based on the basic three steps of fish diets composition research,such as (1) sample collection,(2) diets composition analysis,and (3) gathers and analysis of experiment results,some methods a- bout these steps from inside and outside of China are introduced in this paper respectively.
