A heat-flow sensor that includes an insulating layer, a magnetic field application layer arranged on a first surface of the insulating layer and composed of a conductor, and a heat-flow detection layer arranged on a second surface of the insulating layer, the second surface facing the first surface, and the heat-flow detection layer composed of a conductive magnetic body. The heat-flow detection layer faces the magnetic field application layer via the insulating layer.

This invention prevents measurement error from becoming large in thermoelectric conversion coefficient evaluation and enhances evaluation efficiency. This invention is a physical property evaluation device for evaluating the physical properties of a plurality of solid materials formed on a substrate. The physical property evaluation device comprises an electromotive force measurement means that forms closed circuits including the individual solid materials and measures the electromotive forces occurring at the two ends of each of the solid materials, a means for producing heat flow within the individual solid materials, an external magnetic field generation means for generating a uniform magnetic field having a given intensity and direction in the vicinity of the individual solid materials, and an automation means for evaluating the physical properties of the individual solid materials using the electromotive force measurement means, heat flow production means, and external magnetic field generation means.

Physical property evaluation device

A thermoelectric conversion element that has a power generation layer containing an iron-aluminum based magnetic alloy material containing equal to or more than 70 weight percent of iron and aluminum in total. The power generation layer generates an electromotive force, due to an anomalous Nernst effect that develops in the magnetic alloy material in response to a temperature gradient applied thereto, in a direction intersecting both the magnetization direction of the magnetic alloy material and the direction of the applied temperature gradient.

Thermoelectric conversion element

A channel () formed in a substrate () branches into channels () at a branch point (). On this branch point, obstacles () having a columnar structure are aligned at certain intervals.

After a sample is previously separated into plural components in a channel formed in a microchip (), the channel is irradiated along a separation direction with a laser beam from a laser oscillator () to sequentially ionize each fraction separated in the channel. The ionized fraction is detected by a mass spectrometry unit () and analyzed by an analytical result analyzing unit (). The analytical result is stored in a memory () while associated with position information in a driver control unit () and information on laser beam irradiation condition in a laser control unit (), and the analytical result is imaged by an imaging unit (). The imaged analytical result is displayed on a display ().

Mass spectrometric system and mass spectrometry

A liquid sample () introduced in a main flow passage () is held in a dam portion (), and a trigger liquid () is filled in a trigger flow passage (). In this state, the trigger liquid () is further introduced at desired timing into the trigger flow passage () so that the front end portion of the level of the trigger liquid () is advanced and the front end portion is brought to be into contact with the dam portion (). This causes the liquid sample () to move to the right (downstream side) in the figure, resulting in the liquid sample () flowing out to the downstream side of the main flow passage (). This means that the trigger liquid () provides priming to realize a liquid switch.
