摘要： An injection apparatus of the present invention includes a first switching valve RV1 which is selectively connected to any of a plurality of injectors 21-30 at one end sides thereof; a second switching valve RV2 which is selectively connected to any of the plurality of injectors at the other end sides thereof; a third switching valve RV4 which is connected to the second switching valve and is selectively connected to any of a plurality of columns 31-40 at one end sides thereof; and a fourth switching valve RV5 which is selectively connected to any of the plurality of columns at the other end sides thereof A sequential switching of these four switching valves can permit the sample liquids in the injectors 21-30 to be delivered in sequence into any selected column 31-40, and as such can allow the sample liquids packed in the plurality of injectors to be efficiently dispensed or analyzed by a chromatograph.

摘要： A liquid chromatograph control apparatus (1) includes a measured value storage (25a) that stores a measured retardation factor (Rf) value of a sample (3), which is obtained when components of the sample are separated on thin layer chromatography using eluent (4) containing a plurality of ingredients at a specified mixture ratio, in association with the specified mixture ratio, a rate-of-change-in-Rf-value storage (25b) that stores a rate of change in the Rf value of the sample (3) with respect to variation in mixture ratio of ingredients of eluent (10), a mixture ratio calculator (22a) that determines a mixture ratio of the eluent (10) at which a specified retardation factor value (RfO) of the sample is obtained, based on the measured Rf value corresponding to the specified mixture ratio stored in the measured value storage (25a) and on the rate of change in the Rf value stored in the rate-of-change-in-Rf-value storage (25b), and a mixture ratio controller (22b) that outputs a control signal to control the mixture ratio of the eluent (4) fed into a column (18) so that the Rf value of the sample (3) can be equivalent to the specified retardation factor value (RfO), based on calculated results by the mixture ratio calculator (22a).
