Title: Preparation of filler for high-performance liquid chromatography
Inventor: ODA HIROSHI
IPC: G01N30/56
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To make a liquid chromatograph to sufficiently display a separating performance which a filler has, by adopting a nitrogen flash drying method in order to dry and remove a coating solvent. SOLUTION: As a substance, with which a carried is coated and which has a separating function, it is preferable to use a polysaccharide derivative. As the kind of the polysaccharide derivative, an ester derivative, a carbonate derivative or the like is enumerated, but an aromatic carbonate derivative is preferable. On the other hand, as a carrier, it is preferable to use an inorganic carrier, but it is especially preferable to use silica gel. Then, in a coating operation, a polysaccharide aromatic carbonate derivative is dissolved in a solvent so as to be used as a dope, and it is dropped slowly while it is stirred in the carrier, and the carrier is coated uniformly. At this time, in order to remove the coating solvent after the coating operation, a nitrogen flash drying method is used, and the solvent is heated under a nitrogen flash so as to be dried and removed.  In this manner, it is possible to prepare a filler which sufficiently displays a separating performance.
