A sample plate supply control device controls supply of a sample plate from a sample plate holder having a plurality of sample plate containers to an autosampler, and includes an identification information recognizer that recognizes identification information of a contained sample plate when a sample plate is contained in one sample plate container among the plurality of sample plate containers, and a supply instructor that instructs the sample plate holder to supply the sample plate contained in the one sample plate container to the autosampler in a case where identification information of a subject sample plate to be analyzed matches the identification information recognized by the identification information recognizer.

Sample plate supply control device, sample plate supply control system, sample plate supply control method and non-transitory computer readable medium storing sample plate supply control program

A controller for controlling the operations of an autosampler, a sample push unit, and a make-up unit includes a pump stop timing setting unit for setting a first timing Tof completion of dilution of a sample, and a subsequent second timing Tof completion of trapping of a sample in the trap column, a dilution control unit for causing a solvent delivery pump for make-up of the make-up unit to operate, and for stopping operation of the solvent delivery pump for make-up at the first timing Tset by the pump stop timing setting unit, and a sample push control unit for causing a solvent delivery pump for sample push of the sample push unit to operate, and for stopping operation of the solvent delivery pump for sample push at the second timing Tset by the pump stop timing setting unit.

Sample concentration device

An autosampler includes a flow path switching valve to which a sample push unit and an analysis flow path are connected, a sample loop connected to the flow path switching valve, a sampling needle connected to the flow path switching valve, a metering pump connected to the flow path switching valve, and a control unit for controlling operations of the flow path switching valve and the metering pump. The control unit includes an injection volume addition unit for adding up injection volume of a same sample component injected into the sample loop.

Autosampler

A liquid chromatograph analysis apparatus includes: a macro storing section for storing a macro program having various commands related to a purge operation; a macro executing section for reading the macro program and analyzing and executing the program thus read; and a solvent database in which information on properties of solvents are stored. Based on information input by a user and the information stored in the solvent database, an optimum condition value is determined. Thus, a macro creating function for creating the macro program having operation commands based on the optimum condition value is provided. Further, the macro program can be instantly executed by operating a switch attached to the apparatus body.

Liquid chromatograph analysis apparatus and method

A built-in analyzer controller including: a device controlling circuit for controlling the hardware of an analyzer; a network interface circuit for connecting the analyzer to a network; and built-in programs including a server program for performing a communication through the network interface using a predetermined communication protocol between the analyzer and an external terminal. The server program performs the processes of: sending information of the operating status of the analyzer to the external terminal on receiving a request for the same from the external terminal; and setting a control parameter of the analyzer using the device controlling circuit on receiving a request for setting the control parameter from the external terminal. Using the analyzer controller, the user can monitor and control an analyzer or analyzers connected to a LAN from a remote place, without requiring special programs, and at low cost.

Controller for an analyzer

The present invention proposes an analyzing apparatus by which the operator can easily obtain the management information and/or the analysis progress information of plural apparatuses without going around to check the plural analyzing apparatuses one after another. In a liquid chromatographas an embodiment of the present invention, an individual management information collectorcollects individual management information of the apparatus through an internal communication interfaceExamples of the individual management information include: state of operation; operator name; control information of a liquid supply pumpan automatic samplera column ovenand a detector. A total management information collectorsearches the network for other liquid chromatographscollects the individual management information of said other liquid chromatographsand combines the collected information and the individual management information of the liquid chromatographto form total management information. The total management information is shown to the operator on a displayor a web serverpublishes the information to networkthrough a network interface
