A controller sets a schedule in which an order of a plurality of electrophoresis processes is defined. The controller controls a storage device to store first information representing a result of an electrophoresis process that has ended among the plurality of electrophoresis processes and second information about setting for the plurality of electrophoresis processes. The controller receives a stop signal from an information processing apparatus while the plurality of electrophoresis processes defined in the schedule are being performed. When the controller receives the stop signal, the controller controls an electrophoresis mechanism to perform until the end, an electrophoresis process that is being performed among the plurality of electrophoresis processes. When the controller receives the stop signal, the controller maintains storage of the first information stored in the storage device and the second information on an electrophoresis process that has not yet been performed among the plurality of electrophoresis processes.

Electrophoresis apparatus, electrophoresis system, and method of controlling electrophoresis apparatus

A sample setting section in which at least one sample to be subjected to electrophoresis analysis and at least one standard sample are set, and a controller. The controller includes a standard data storage memory that stores standard data obtained by performing electrophoresis analysis of a standard sample under a predetermined condition, and a chip determination part configured to perform electrophoresis analysis of the standard sample under the predetermined condition using each of the at least one microchip before electrophoresis analysis of the sample set in the sample setting section is performed to acquire analysis data on the standard sample by the detector, and to perform a chip determination as to whether a state of each of the at least one microchip is suitable for performing electrophoresis analysis by comparing the acquired analysis data with the standard data on the standard sample.

Microchip electrophoresis device

An analyzer includes a separation data holding part, a determination criterion holding part, and a component peak determination part. The separation data holding part retains, as reference data, separation data obtained by an electrophoresis analysis for a reference sample including a reference component which is a known component and retains, as data to be analyzed, separation data obtained by an electrophoresis analysis for a sample to be analyzed. The determination criterion holding part retains a determination criterion for determining whether a component peak in the reference data and a component peak in the data to be analyzed are identical. The component peak determination part is configured to determine whether the component peak in the reference data and the component peak in the data to be analyzed are identical to each other, using the determination criterion.

Electrophoresis separation data analyzer

An electrophoretic separation data analyzing apparatus includes an analysis target peak identifying part configured to require a user to input analysis target peak information on analysis target peaks to be added to an analysis target in separation data obtained by electrophoretic separation, and to identify at least one of the analysis target peaks based on the analysis target peak information, a peak-of-interest identifying part configured to require the user to input peak-of-interest information on a peak of interest among the analysis target peaks, and identify the peak of interest based on the peak-of-interest information, and an abundance ratio calculating part configured to determine an abundance ratio of the peak of interest among all of the analysis target peaks based on a total value of peak areas of the analysis target peaks and a peak area value of the peak of interest.

Electrophoretic separation date analyzing apparatus, electrophoretic separation data analyzing method, and computer program for causing a computer to execute the analyzing method

In an electrophoresis method, a capillary plate having a capillary channel is maintained in a predetermined temperature to be processed, and a sample is filled into the capillary channel. A solution is prepared to have a temperature substantially the same as the predetermined temperature of the capillary plate, and the solution is injected into the capillary channel maintained in the predetermined temperature. Voltage is applied between two ends of the capillary channel to perform electrophoresis of the sample.
