Abstract
In an analysis system for detecting amounts of components contained in samples, many samples can be measured simultaneously in the whole of the system by use of compact inexpensive photometers. An LED with low heat generation and a long life span is used as a light source. Compactness is achieved by bended optical axis instead of a straight one. Components for bending an optical axis and components for condensing light to ensure an amount of light are in common use to reduce the number of components. Compactness, reduction of the number of components, and integration achieve easy optical axis alignment and precise measurement.
Claims26
A photometer comprising:
- a light source;
- a first support transmitting or passing light emitted from the light source therethrough;
- a detector for detecting light passed through a reaction vessel containing a measurement sample;
- a second support provided with the detector, the first support and the second support being disposed such that the reaction vessel containing the measurement sample can be inserted therebetween;
- a first reflection section provided to the first support, reflecting light emitted from the light source and passing the light through the reaction vessel;
- and
- a condensing section for condensing the light emitted from the light source and passing the light through the reaction vessel.
An analysis system for an analysis device,
- the analysis device comprising:
- a reaction vessel containing a measurement sample;
- a thermostatic bath having a constant temperature fluid to immerse and hold the reaction vessel;
- and
- a photometer illuminating the reaction vessel with light and provided to a bottom portion of the thermostatic bath,
- the photometer comprising:
- a light source;
- a first support transmitting or passing light emitted from the light source therethrough;
- a detector for detecting light passed through the reaction vessel;
- a second support provided with the detector;
- and
- a reflection section provided to the first support, reflecting light emitted from the light source, and passing the light through the reaction vessel,
- the first support and the second support being disposed to insert the reaction vessel therebetween.
