Title:
LIQUID CHROMATOGRAPHY
Document Type and Number:
Japanese Patent JP3222759
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain an accrete obstacle avoiding means, in a liquid chromatograph having a plurality of chromatograph units, by obtaining data for analayzing an obstacle without relying on manual work and preventing the defficiency of necessary data or the posting error of data.
SOLUTION: The constitution of respective machineries such as a pump 4, an automatic sampler 5, a detector 6 or a column oven 7 at every chromatograph unit 3 is stored in a main memory part 2b as a system configuration file and the analyzing conditions of the respective machineries are also stored in the main memory part 2b. When an error is generated in the chromatograph unit 3, data processing is performed on the basis of the inherent data and analytical data of the respective machineries in the main control part 2a of a data processor 2 to form an obstacle analyzing data file which is, in turn, allowed to correspond at every system configulation file of the main memory part 2b to be stored.
