Abstract: In order to efficiently obtain data for calculating retardation values at a plurality of wavelengths, a sample having birefringence is placed between a polarizer and an analyzer, which are maintained in a parallel nicol relation to each other and rotated about an optical axis of measuring light. White measuring light is applied through the polarizer so that the light being passed through the sample and transmitted through the analyzer is received by a polychromator. A one-dimensional optical sensor is arranged on an outgoing imaging surface of the polychromator, to simultaneously detect transmitted light intensity values of a plurality of wavelengths. Since transmitted light intensity values of a plurality of wavelengths are obtained every polarization rotation angle of the polarizer and the analyzer, it is possible to obtain dispersion of retardation values with respect to wavelengths and the like by processing the data.

Abstract: In order to satisfy both of high-sensitivity and low-sensitivity applications with no replacement of a flow cell, a photodetector (30) is divided into four portions (44-1, 44-2, 44-3, 44-4) by a first straight line (40) which is perpendicular to a direction of movement of a slit image (6) and a second straight line (42) which is inclined with respect to the direction of movement of the slit image (6) to intersect with the first straight line (40). Assuming that S.sub.1, S.sub.2, S.sub.3 and S.sub.4 represent intensity levels of detection signals of the photodetector portions respectively, the signals are processed along the following equations in analysis and preparative modes respectively:Sa=c{(S.sub.2 +S.sub.3)--(S.sub.1 +S.sub.4)}/{(S.sub.2 +S.sub.3)+(S.sub.1 +S.sub.4)]}Sp=c{(S.sub.1 +S.sub.2)--(S.sub.3 +S.sub.4)}/{(S.sub.1 +S.sub.2)+(S.sub.3 +S.sub.4)]}.

Abstract: Disclosed herein is an optical organism measuring apparatus in which cables provided on both light transmission and receiving sides are sufficiently reduced in diameter and provided with flexibility for attaining handleability while light can be transmitted and received in high efficiency so that information can be obtained from a deep portion in an organism. Semiconductor lasers (2-1, 2-2, 2-3) are coupled with incident ends of a plurality of single core optical fibers which are contained in a flexible probe (12), so that laser light guided by the single core optical fibers is applied to an organism (8) from a forward end portion of the probe (12). A light receiving probe (18) is provided on its forward end with a silicon photodiode (14), which is attached in close contact to the organism (8) to receive light transmitted through or reflected by the organism (8). This silicon photodiode (14) is integrated with a preamplifier (16).

The sampling needle is adapted to introduce samples as well as to distributively inject acid into sample containers. The ventilation pretreatment needle is adapted to stir samples during sampling as well as to pretreat next samples during analysis.

Abstract: A sample injector (32) with an upwardly opened sample receiving hole is connected to an atomizer (36) of a flame type atomizing means and on a burner chamber (7) a flameless type atomizing means is mounted ahead of a burner head (9). For distribution of the sample by an auto-sampler (40) it is so arranged that the nozzle is movable to the sample bottle of the auto-sampler (40) and the sample injector (32) or a sample injection hole (30) of the atomizing means placed at the measuring position. This arrangement enables injection of the sample into the atomizing means of either type by means of a common auto-sampler, this facilitating switching between the flame system and the flameless system.

Abstract: A measuring part measures the absorbance spectrum of an effluent fluid sample from a chromatograph in a constant cycle, and a base line calculating part calculates a base line including absorbance values on both ends of a designated wave number range with respect to every absorbance spectrum data as measured. A peak area calculating part calculates the peak area of the absorbance spectrum in the designated wave number range on the basis of the decided base line. A chromatogram is obtained by time change of the calculated peak area. Thus, it is possible to eliminate influences by other functional groups and fluctuation of the base line in an absorbance analyzer.

Abstract: Disclosed herein is a two-dimensional electrophoresis apparatus comprising a first-dimensional electrophoresis part (5), a second-dimensional electrophoresis part (6) and a transcription part (7). The transcription part (7) transfers a first-dimensional gel completely electrophoresed by the first-dimensional electrophoresis part (5) from a first-dimensional gel housing (20) to one end of a second-dimensional gel housing (30). Thus, a two-dimensional electrophoresis can be automatically executed, thereby improving reproducibility of separated images and separative power.

Abstract: Relation of the degree of interference to interference concentration is previously stored with respect to at least one interference gas influencing an oxygen indicated value of a sample gas, so that interference corresponding to interference gas concentration of the sample gas is corrected on the basis of the stored relation when oxygen concentration is calculated from a detection signal of an oxygen sensor and outputted. Concentration of the interference gas, with respect to which the relation of the degree of interference is stored, is manually inputted in measurement, or previously set. When the concentration of the interference gas is previously set, such concentration is made changeable by manual input. Thus, even if the sample gas contains an interference gas in high concentration as in the case of an exhaust gas containing highly concentrated CO.sub.2 gas, it is possible to accurately measure oxygen concentration of the sample gas.
