Abstract: 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.

Abstract: 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 T1 of completion of dilution of a sample, and a subsequent second timing T2 of 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 T1 set 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 T2 set by the pump stop timing setting unit.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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 chromatograph 201 as an embodiment of the present invention, an individual management information collector 20 collects individual management information of the apparatus through an internal communication interface 28. Examples of the individual management information include: state of operation; operator name; control information of a liquid supply pump 4, an automatic sampler 6, a column oven 8 and a detector.

Abstract: The present invention provides a network-capable analysis data processing system and an analyzing apparatus, for which an external client application program or an information-processing system to be used as a counterpart of the communication can be easily developed with smaller amounts of time and labor. According to the present invention, the interface of the server 18 installed in an analyzing apparatus 10 is designed in conformity with generally used technical standards that are free from any limitation prescribed by specific vendors, and a WSDL document 24, in which the server interface is specified in a standard description language, is published to external systems 16. Developers of the external systems 16 can use an existing development tool that automatically creates a communication module 30 from the specification 24. The availability of this communication module 30 will facilitate the development of an application program that communicates with the server 18.

Abstract: The present invention provides a remote support system for diagnosing or analyzing a fault of an analyzing apparatus from a remote service support terminal without lowering the security of the user's intranet. In an embodiment of the invention, the system includes an analyzing apparatus 8 having a communication controller 81 and connected via the user's intranet 7 to the Internet 1, a terminal 5a or 5b connected via the manufacturer's intranet 4 to the Internet 1, and a server 2 accessible through the Internet 1. In a polling communication, the terminal 5a or 5b as the master sends a control command to the server 2 as the slave. In another polling communication, the analyzing apparatus 8 as the master receives the control command from the server 2 as the slave. Such a two-stage communication process makes it possible to control the analyzing apparatus 8 for the purpose of analyzing the log or maintenance information and troubleshooting the problem while maintaining the security level of the intranet 7.

Abstract: The image processing performance of a present day or existing page printer, e.g., electrophotographic printer, is improved and accelerated with the use of a detachable intelligent cartridge which contains a CPU and necessary memory to process print data into image dated for the electronic control unit of the printer to which the cartridge is attached. Depending, upon the page description language (PDL) to be employed, a cartridge can be selected for use with the printer and accelerate its PDL conversion and printing output. The intelligent cartridge CPU, which is different from the printer CPU, receives print data are from the printer and, since the data bus connecting the intelligent cartridge and the electronic control unit of the printer has only a read only capability from the electronic control unit, data transfer to the cartridge is made possible by utilizing the print data as an index for the read address accomplished by the printer CPU.
