Abstract:
1. A chromatography quantitative measuring apparatus for applying a beam to a chromatography specimen on which a sample is added, detecting an optical signal from a transmitted light or reflected light from the chromatography specimen, and quantitatively reading a concentration of the sample from the detected optical signal, said apparatus comprising: a laser for emitting a beam to the chromatography specimen; and an optical mechanism for forming the beam emitted from said laser into an elliptically-shaped beam having an area smaller than a detection area of the chromatography specimen and applying the elliptically-shaped beam to the chromatography specimen such that a long side of the elliptically-shaped beam applied to the chromatography specimen is shorter than a width of the chromatography specimen in a width direction of the chromatography specimen perpendicular to a longitudinal direction of the chromatography specimen, and a short side of the elliptically-shaped beam applied to the chromatography specimen is shorter than a width of the detection area of the chromatography specimen, said optical mechanism comprising:
