摘要： In a pre-processing system, a state in which a sample dispensing probe 20a and a syringe pump 81 communicate with each other through a channel 91 and a state in which the sample dispensing probe 20a and a culture tank 301 communicate with each other through the channels 91, 93, and 94 can be switched by operation of the three-way valves 82 and 83. For this reason, the liquid sample in the culture tank 301 can be automatically discharged from the sample dispensing probe 20a without requiring the user to directly sample the liquid sample. As a result, in the pre-processing system, the user's manual sampling work can be omitted, and the user's work can be simplified.

摘要： A spectrophotometer in which a normal plane to a diffraction grating is inclined with respect to an optical axis of an incident light passing through a slit, the normal plane to the diffraction grating passing through an intersection point between the optical axis of the incident light i and a grating surface of the diffraction grating. The diffraction grating and a photodiode array PDA are placed such that the photodiode array PDA is parallel to the normal plane to the diffraction grating and that a normal plane to the photodiode array PDA includes a line that is symmetrical to the optical axis of the incident light i about the normal plane to the diffraction grating.

摘要： A flow-path member through which a sample flows in an analysis device includes a pipe and a covering member that covers the pipe. The pipe has a first portion including a first direction, which is orthogonal to a direction in which the flow-path member extends as a whole, as at least an element of a local extending direction, a second portion including a second direction, which is opposite to the first direction, as at least an element of a local extending direction, a first bent portion in which a local extending direction changes from the first portion to the second portion, and a second bent portion in which a local extending direction changes from the second portion to the first portion. A space is formed between the covering member and the pipe at least in the first portion and the second portion.

摘要： A liquid sending failure detector acquires periodically a liquid sending pressure of a liquid sending mechanism consecutively sends liquid using at least one plunger pump that sends liquid by reciprocally driving a plunger such that a fluctuation is read in one driving period of the liquid sending mechanism, and detect a liquid sending failure of the liquid sending mechanism using an acquired liquid sending pressure. The liquid sending failure detector executes a pulsation detection step of obtaining a fluctuation range of the liquid sending pressure in a certain driving period of the liquid sending mechanism and detecting pulsation on a condition that a count of consecutive periods in which the fluctuation range exceeds a predetermined reference value exceeds a predetermined reference count, and a liquid sending failure detection step of detecting a liquid sending failure of the liquid sending mechanism when the pulsation is detected in the pulsation detection step.

摘要： A first liquid sending controller of an analysis control device controls a first liquid sender such that a mobile phase is supplied to a fluorescence detector through an analysis column and a junction during an analysis of a sample. A sample introduction controller controls a sample introducer such that the sample is introduced into a mobile phase by the sample introducer at a position farther upstream than the analysis column during the analysis of the sample. The second liquid sending controller causes a second liquid sender to start supplying a fluorescent reaction liquid such that the fluorescent reaction liquid arrives at the junction later than a point in time at which supply of the mobile phase starts and before the sample introduced into the mobile phase arrives at the junction during the analysis of the sample. A generator generates a chromatogram based on an output signal of the fluorescence detector during the analysis of the sample.

摘要： The flow cell is composed of a cell block and a cell holder. The cell block is light transmittable and is provided with a plurality of cells communicated with each other and mutually different in optical path length and an inlet and an outlet communicated with the cell. The plurality of cells include a short optical path length cell having an optical path length of 100 μm or less. The short optical path length cell is constituted by a groove formed on an inner joining surface of a plurality of laminated light transmitting substrates. The optical path length of the short optical path length cell is defined by a depth of the groove. The cell holder is configured to accommodate the cell block therein, and is provided with an incident window for allowing light to enter the cell block and an emission window for emitting the light transmitted through the cell block.

摘要： A problem addressed by the present invention is to reduce the influence of stray light incident on each light-receiving element in the case of receiving each wavelength of light using a plurality of light-receiving elements. The multichannel spectrophotometer according to the present invention is a detector for simultaneously detecting the entirety of wavelength-dispersed light obtained by introducing light from a sample to a light-dispersing element (16) and dispersing this light into wavelengths by the light-dispersing element (16), including: a multichannel-type detector (17) including a plurality of light-receiving elements arranged in a one-dimensional form in a wavelength-dispersing direction of the light-dispersing element; a light amount calculator (221) for calculating the amount of light from a detection signal of each of the plurality of light-receiving elements (PD); a spectrum creator (222) for creating, from the amounts of light calculated by the light amount calculator (221), a spectrum showing a relationship between wavelength and the amount of light; and a computing section (224) for estimating, from the spectrum, the amount of stray light incident on each light-receiving element (PD) and correcting the spectrum by subtracting, from the amount of wavelength-dispersed light incident on each light-receiving element, the amount of stray light.
