Abstract:
The present invention relates generally to the field of biochemical laboratory instrumentation for different applications of measuring properties of samples on e.g. microtitration plates and corresponding sample supports. The object of the invention is achieved by providing an optical measurement instrumentation wherein a sample (281-285) is activated (212AS, 218AS) and the emission is detected (291, 292), wherein between the activation and detection phases of measuring the sample, a shift is made in the relative position between the sample and means (218) directing the activation radiation to the sample as well as in the relative position between the sample and the means (293) receiving the emission radiation from the sample. This can be implemented e.g. by moving (299) the sample assay plate and/or a measuring head between the activation and emission phases of a sample. The invention allows a simultaneous activation of a first sample and detecting emission from a second sample thus enhancing efficiency of the measurement.

A blood analysis apparatus is provided. The blood analysis apparatus includes: a chip holding portion (22) having an aperture (23) which allows light to pass therethrough and holding a µ-TAS chip for holding a measurement liquid; a rotary body (25) on which the chip holding portion (22) is mounted; a light source (41); and a light-receiving unit (43). A measurement position of the rotary body (25) at which the measurement liquid is to be measured with the light from the light source (41) is set by: rotating the rotary body (25) to obtain a light value of light which is emitted from the light source (41) and received by the light-receiving unit (43) through the aperture (23); and setting a rotational position of the rotary body (25) where the light value is a threshold value or more, as the measurement position.
Abstract:
A light amount is increased and an analyzing accuracy can be increased in accordance with an enlargement of a load angle.. However, scattered light tends to be loaded into a light receiving element in an analysis accompanied by scattered light, and the dynamic range of a concentration which can be measured becomes narrow. In the invention, light is dispersed by a light dispersing portion (20), a load angle of the received light is changed per wavelength, the load angle is made larger for light of a wavelength having a small light amount, and the load angle is made smaller for light of a wavelength having a large light amount and used for an analysis accompanied by scattered light. Accordingly, it is possible to gain a dynamic range of a concentration which can be measured in the analysis accompanied by scattered light, while increasing the light amount and maintaining the analyzing accuracy.
