SIZE EXCLUSION CHROMATOGRAPHY ANALYZER AND LOW MOLECULE PEAK SEPARATION COLUMN

摘要

PROBLEM TO BE SOLVED: To provide a size exclusion chromatography analyzer for measuring high molecule compound capable of measuring a sample of molecule amount of 100 to 2000 without being subjected to influences of ghost peak derived from mobile phase, and a low molecule peak separation column.;SOLUTION: Disclosed size exclusion chromatography analyzer includes a column filled with copolymer particles, in which converted volume average particle diameter is 4.0 μm or less, and the average pore diameter is 1 to 6 nm, which are filled in a housing of 35 mm or more in length, is connected at the downstream of an analytical column and upstream of a detector.;SELECTED DRAWING: None;COPYRIGHT: (C)2018,JPO&INPIT
