ABSTRACT:
TECHNICAL FIELD
The present invention relates to a sensor. More particularly, the present invention relates to a sensor which is suitable for performing measurement of objects (for example, test solution) using a micro-plate which has object housing chambers of multiple lines and multiple columns.
BACKGROUND ART
From the past, a micro-plate (a micro-plate for a high throughput system) is supplied which has object housing chambers (cells) of multiple lines and multiple columns. The micro-plate determined its specification in size, number of cells, pitch between cells and the like. The micro-plate is popularly supplied which has cells of 8-lines and 12-columns.
When a dissolved oxygen amount is to be measured, for example, a sensor is employed in the past which is arranged as a single sensor. That is, the sensor arranged as a single sensor is intruded in one cell so that the sensor is contacted to the object which is housed within the cell and that an electrical signal is output therefrom which represents a measurement result.
When the above measurement is carried out, the sensor or multiple sensors should be contacted to the object by intruding the sensor arranged as a single sensor into each cell sequentially, or by intruding multiple sensors each being arranged as a single sensor into corresponding cells, so that disadvantages arise in that much labor is required for the measurement and that dispersion is generated in measerement data. Further, a disadvantage arises in that a number of objects is limited which can be measured at one measuring operation, because of spatial limitation and limitation in measurement labor.
The present invention was made in view of the above problems.
It is an object of the present invention to offer a sensor which can greatly reduce measurement labor, can greatly reduce dispersion in measurement data, and can lighten the limitation in the number of objects which can be measured at one measuring operation.
DISCLOSURE OF INVENTION
A sensor according to the present invention disposes multiple electrode sections spaced at intervals according to each of an every predetermined distance, each electrode section having at least an active electrode and a counter-electrode, unites the all electrode sections and multiple lead-out terminals which output measurement signals of each electrode section.
A sensor according to the present invention comprises a base body having a plate shape, projection sections provided at an outer predetermined position at every predetermined distance, at least active electrodes and counter-electrodes provided at a predetermined position of each projection section, and multiple lead-out terminal for outputting measurement signals of each electrode section, the lead-out terminal being provided at a predetermined position of the base body which position opposes to a portion at which the projection section is provided.
A sensor according to the present invention further comprises a connector which is connected to the lead-out terminals in a removable manner and an amplifier which amplifies the measurement signals output through the lead-out terminals, wherein the connector and the amplifier are united in one body.
A sensor according to the present invention employs a connector which connects multiple base bodies in parallel to one another and in a removable manner, and employs an amplifier which amplifies measurement signals, respectively, each measurement signal being output through the corresponding lead-out terminal.
A sensor according to the present invention comprises multiple object housing chambers, and wherein electrode sections each having at least an active electrode and a counter-electrode are formed at a bottom section of each object housing chamber, and multiple lead-out terminals for outputting measurement signals of each electrode section are united to the object housing chambers.
A sensor according to the present invention comprises a base body having a plate shape, projection sections of multiple lines and multiple columns, each projection section being projected by a predetermined angle with respect to one surface of the base body, electrode sections each including at least an active electrode and a counter-electrode which electrode section is provided at a predetermined position of each projection section, and multiple lead-out terminals for outputting measurement signals of each electrode section which lead-out terminals are provided at predetermined positions on an edge section of the base body.
A sensor according to the present invention comprises multiple object housing chambers, and wherein multiple electrode sections each having at least an active electrode and a counter-electrode are formed on a bottom inner face of each object housing chamber, and multiple lead-out terminals for outputting measurement signals of each electrode section, each lead-out terminal being provided so that the lead-out terminal is exposed at an outer face of a bottom section of each object housing chamber.
A sensor according to the present invention comprises multiple object housing chambers, multiple inner projections each projecting to inner side from a center section of an inner face of an edge section of each object housing chamber, multiple electrode sections each having at least an active electrode and a counter-electrode, each electrode section being formed at a predetermined position of outer face of the inner projection and/or the inner face of the edge section, and multiple lead-out terminals for outputting measurement signals of each electrode section, each lead-out terminal being provided so that the lead-out terminal is exposed at an outer face of a bottom section of each object housing chamber.
A sensor according to the present invention employs an axial section as the inner projection which axial section extends upwards from a central section of the bottom inner face of each object housing chamber, and employs an electrode section which has an active electrode on an outer face of the axial section and a counter-electrode on an upper face of the bottom section.
When the sensor according to the present invention is employed, multiple electrode sections and multiple lead-out terminals can be handled in one body, labor for measurement is greatly reduced and dispersion in measurement data is greatly reduced, a spatial limitation and limitation in measurement labor are greatly reduced, and, limitation in a number of objects which can be measured at one measurement operation is lightened, because the sensor disposes multiple electrode sections at every predetermined distance, each electrode section having at least an active electrode and a counter-electrode, unites the all electrode sections and multiple lead-out terminals which output measurement signals of each electrode section.
When the sensor according to the present invention is employed, an operation and effects can be realized which are similar to those discussed, because the sensor comprises a base body having a plate shape, projection sections provided at an outer predetermined position at every predetermined distance, at least an active electrode and a counter-electrode provided at a predetermined position of each projection section, and multiple lead-out terminals for outputting measurement signals of each electrode section, the lead-out terminal being provided at a predetermined position of the base body which position opposes to a portion at which the projection section is provided.
When the sensor according to the present invention is employed, the measurement signals which are low in their level are immediately amplified so that noise resistance is improved, and an operation and effects can be realized which are similar to those discussed, because the sensor further comprises a connector which is connected to the lead-out terminals in a removable manner and an amplifier which amplifies the measurement signals output through the lead-out terminals, wherein the connector and the amplifier are united in one body.
