Abstract: An information management system for detecting not only a set of management target data which has been changed but also another set of management target data which is affected by that change among a plurality of sets of management target data. The present system includes a dependency manager for managing the association of one set of management target data with another set of management target data which depends on the former set of management target data; and an inspector for detecting a set of management target data which is affected by a change in another set of management target data.

Abstract: A gas chromatograph device (100) includes a calculator (2) configured to acquire information on conduits (36) between a branch unit (33) and detectors (34) and information that identifies types of the detectors connected to the conduits, the calculator being configured to calculate at least one of gas flow rates in the conduits, gas linear velocities in the conduits, or a pressure in the branch unit based on the acquired information.

Abstract: A liquid chromatograph 1 includes a weight measuring device 21 and a control device 30. The control device 30 includes a liquid amount detection processor 301. The weight measuring device 21 measures the weight of the first mobile phase container 6, the second mobile phase container 8, or the waste liquid container 13. The liquid amount detection processor 301 detects the amount of the mobile phase or the amount of the waste liquid based on the weight measured by the weight measuring device 21. For this reason, the amount of the mobile phase or the amount of the waste liquid can be detected without providing a flow sensor or the like in a channel. As a result, the delivery of the mobile phase can be kept in a smooth state. Further, even in a case where a problem occurs in the channel of the mobile phase, the first pump 7, and the second pump 9, the amount of the mobile phase or the amount of the waste liquid can be detected. Furthermore, the amount of the mobile phase or the amount of the waste liquid can be detected without being affected by the shape of each container. For this reason, the amount of the mobile phase or the amount of the waste liquid can be accurately detected.

Abstract: When an operation receiver receives an operation for starting automatic start-up processing, a display controller causes a display to display a first direction image indicating a working order of a plurality of objects to be controlled, sequentially changes a display mode of a status image corresponding to an object that has worked to a first mode, and changes a display state of each of a plurality of operation images to an operable first state or an inoperable second state. When the operation receiver receives an operation for starting automatic stop processing, the display controller causes the display to display a second direction image indicating a stopping order of the plurality of objects in a reversed manner of the first direction image, sequentially changes a display mode of a status image corresponding to an object that has stopped to a second mode.

Abstract: Disposition of a wrong liquid for analysis or a liquid for analysis connected to a wrong pipe is detected as abnormal use. A liquid-for-analysis monitor includes: a weighing scale that weighs a container that contains a liquid as a liquid for analysis that needs to be used in analysis; a density storing part that stores a density ρ of the liquid for analysis; and a liquid-for-analysis determining part configured to obtain a variation ΔM between a weight of the container weighed by the weighing scale before a decreasing operation that decreases the liquid for analysis and a weight of the container weighed by the weighing scale after the decreasing operation, and determine whether the liquid for analysis has been normally used in the decreasing operation or not, based on the obtained variation ΔM, a volume V of the decrease in the liquid in the container in the decreasing operation, and the density ρ of the liquid for analysis stored in the density storing part.

Abstract: A first power consumption measuring unit 5 measures only the power consumption of a pump 21 that is a reference unit of a liquid chromatograph 2. A second power consumption measuring unit 6 measures only the power consumption of a gas chromatograph main body 31 that is a reference unit of a gas chromatograph 3. An operating information acquiring unit acquires pieces of operating information on an automatic sampler 22, an oven 23, and a detector 24 that are target units of the liquid chromatograph 2 based on information on the power consumption of the pump 21. The operating information acquiring unit acquires the operating information on a head space sampler 32 that is a target unit of the gas chromatograph 3 based on information on the power consumption of the gas chromatograph main body 31. Thus, even in the case where the analyzer includes many target units, only the power consumption of the reference units is measured, and the operating time period calculating unit can acquire the pieces of operating information on the target units from the power consumption of the reference units.
