This invention relates to technology for analyzing a specific component in a sample liquid, and provides an analyzing tool and an analyzing apparatus. Analyzing tool (Y) includes a liquid inlet () at a central portion of the tool and a plurality of channels () which communicate with liquid inlet () and move the sample liquid introduced through liquid inlet () by capillary action from the central portion towards a peripheral portion of the tool. Each channel () extends linearly for example from the central portion towards the peripheral portion, and the plurality of channels () are arranged radially.

Analyzing tool and device

In order to provide a high-performance electrophoresis chip and an electrophoresis unit having the same that can restrain the diffusion of sample at an intersection between the electrophoresis groove and the sample introduction groove and prevent decrease in contrast and decrease in resolution, an electrophoresis chip is provided with a sample introduction groove, an electrophoresis groove, and a through hole. The sample introduction groove, the electrophoresis groove, and the through hole are formed on different substrates. In the electrophoresis chip, by combining the substrates, the sample introduction groove and the electrophoresis groove are located in different planes.

Electrophoresis chip and electrophoresis unit having the same

An analyzing tool (Y) has a liquid-introducing opening (), one or more flow passages () through which a sample liquid introduced from the liquid-introducing opening () is moved, and a separation film () for filtrating the sample liquid supplied to the liquid-introducing opening () and then introducing the liquid filtrated to the one or more flow passages (). The analyzing tool (Y) is structured such that a liquid sample is filtrated by being advanced in the thickness direction of the separation film (). The flow passage () is structured such that the sample liquid is moved by, for example, a capillary phenomenon.

Analytical tool

The invention relates to a method of producing an analytical tool having recesses () formed therein for moving a sample liquid, a base plate () made of polymeric material, and a cover laminated to the base plate () to cover the recesses (). This producing method includes the step of applying a hydrophilic treatment to the inner surfaces of the recesses (). The hydrophilic treatment includes a primary modifying operation for primarily modifying the properties of the inner surfaces of the recesses () by contacting a modifying gas with the inner surfaces of the recesses (), and a secondary modifying operation for secondarily modifying the properties of the inner surfaces of the recesses ().

Method of producing analytical tool

The present invention relates to a technique for causing the temperature of a liquid component retained in an analytical tool () to be adjusted to a target temperature, wherein the analytical tool () is used for analyzing the sample. According to the present invention, the temperature of the liquid component () is raised by heating the liquid component utilizing light energy from a light source (). The temperature raising of the liquid component may be performed by supplying the light energy directly to the liquid component. Alternatively, the temperature raising of the liquid component may be performed by thermal energy transferred from a temperature raise region adjacent to the liquid component to which the light energy supplied. Preferably, as the light source () for raising temperature, use may be made of a laser diode or a light-emitting diode.

Temperature adjusting method for analytical tool and analytical device having temperature adjustment function

An analytical instrument (A) includes a capillary () defined by causing a first member () to cover an opening of a groove () of a second member (). For bonding the first member () and the second member (), the first member () is provided with a bonding surface () made of self-adherent elastomer. Therefore, the bonding of the first member () and the second member () is facilitated, whereby sealing performance around the groove () is improved.
