The disclosure proposes the measurement system as an example, which includes an electrophoresis device and a computer. The electrophoresis device includes a phoresis medium container for storing a phoresis medium, a capillary having its inside filled with the phoresis medium, a delivery mechanism for delivering the phoresis medium in the phoresis medium container to the capillary, and a device control section for controlling an operation of the delivery mechanism. The computer calculates a deliverable number of times from an amount of the phoresis medium in the phoresis medium container and an estimated delivery amount of the phoresis medium delivered by the delivery mechanism (see FIG 16).

A point-of-care diagnostic system that includes a cartridge and a reader. The cartridge can contain a patient sample, such as a blood sample. The cartridge is inserted into the reader and the patient sample is analyzed. The reader contains various analysis systems, such as an electrophoresis detection system that uses electrophoresis testing to identify and quantify various components of the blood sample. The reader can process data from the various patient sample analysis to provide interpretative results indicative of a disorder, condition, disease and/or infection of the patient.

The present disclosure provides a method for screening, isolating and purifying analytes.

In an electrophoresis apparatus using a capillary, electrophoresis using a single capillary sometimes requires replacement of a sieving matrix. Replacement with a different sieving matrix has conventionally required cleaning with sieving matrix cleaning liquid, which has increased costs and time required. An electrophoresis apparatus according to the present invention comprises an anodic capillary head provided at a distal end of the capillary, a sieving matrix container filled with a sieving matrix used for electrophoresis, and a filling mechanism for filling the capillary with the sieving matrix via the sieving matrix container. The filling mechanism fills the capillary, which is already filled with the sieving matrix, with a sieving matrix different from the already-filled sieving matrix without using sieving matrix cleaning liquid.

The present disclosure provides an analysis chip device used in capillary electrophoresis.

An analysis method using a microchip which is provided with a capillary flow path, and a sample reservoir connected to the capillary flow path, in which the capillary flow path is filled with a first liquid for electrophoresis, and a second liquid containing a sample is stored in the sample reservoir, and including a pressurization process in which the first liquid is pressurized into the capillary flow path from a side of the capillary flow path that is opposite from the side connected to the sample reservoir, and a separation process in which a voltage is applied between the sample reservoir storing the second liquid and the capillary flow path filled with the first liquid, such that components in the sample contained in the second liquid move in the capillary flow path and the components are separated in the capillary flow path.

Disclosed is a device for impregnation using electrophoresis, which includes a chassis, a storing unit, a pipeline unit, an injection unit, a bearing tank, a first driver element and a second driver element, wherein the storing unit has several storage tanks storing the materials for impregnation. The pipeline unit has several pipelines connecting the storage tanks and the injection unit.

Described are devices for and methods of modulating a fluid sample. The devices (10, 40, 60, 80, 100, 130, 160, 220) include at least one sample-modulating component (20, 76, 78, 90, 110, 112, 116, 150, 152, 154, 162, 164, 182, 184, 186, 222, and 230) and, in some embodiments, two or more sample-modulating components. The sample-modulating components are each capable of performing a function selected from the following group: concentrating the sample to increase a concentration of a first constituent of the sample; diluting the sample to decrease a concentration of a second constituent in of the sample; desalinating the sample to decrease the total moles of salt in the sample volume or causing a temporary decrease in the osmolarity; adjusting pH of the sample to bring a pH of the sample into a predetermined range; absorbing one or more nonpolar substances to decrease a concentration of the nonpolar substances; and delivering one or more reagents to the sample to provide a desired concentration of the reagent in the sample.
