Abstract: A sample treatment apparatus is designed to directly monitor a pressure signal from a pressure sensor to examine pressure fluctuations resulting from a sample's sway before a discharge of the sample, so that the discharge is performed after the confirmation of the absence of pressure changes. The apparatus has a detection function that allows a discharge to be started even before a pressure fluctuation vanishes completely, by allowing the operator to set a desired number of pressure monitorings, monitoring time, or pressure amplitude. The detection function also allows an alarm to be raised when a pressure fluctuation has not fallen within a given range. The sample treatment apparatus therefore allows discharge of more accurate amounts of samples.

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.

Abstract: There is provided a high-accuracy automatic analysis device achieving both of measurement in a wide concentration range and high sensitivity at a low concentration. The signals of a plurality of wavelengths ?1 to ?12 where the sensitivity of light absorption caused by fine particles is high from a light source 40 are converted to absorbances by a spectroscopic optical system (detector) 41. The absorbances are converted to a secondary parameter from in which a noise component is cancelled by using a previously-defined conversion table 54, so that a concentration of a measured material (predetermined component) is calculated by an operation unit (calculating means) 53 based on the secondary parameter. Thus, analysis being resistant to the noise even at the low concentration can be achieved in a range up to a high concentration.

Thus, the photometric unit is reduced in size.
