CAPILLARY TYPE CONNECTION PIPING WITH LESS DIFFUSION AND IMPROVED THERMAL CHARACTERISTIC FOR LIQUID CHROMATOGRAPHY, PARTICULARLY FOR HIGH PERFORMANCE LIQUID CHROMATOGRAPHY

摘要

PROBLEM TO BE SOLVED: To provide a capillary type connection piping for feeding liquid for liquid chromatography.;SOLUTION: In the capillary type connection piping for feeding liquid for liquid chromatography, connection piping 50 has an inside cross section changing in a main flow direction in regard to the shape and/or position, and forces a flow component changing in a radial direction. The radial mixing of liquid flowing in the connection piping is thereby increased while disturbing and preventing a known parabola flow pattern with a strictly circular cross section.;COPYRIGHT: (C)2009,JPO&INPIT
