    摘要: An object of the present invention is to provide a capillary electrophoresis apparatus in which simultaneity can be ensured between sensitivity and data acquisition to decrease a pull-up signal while spectral data acquisition is eliminated in each capillary exchange. The invention relates to a capillary electrophoresis apparatus characterized in that a multi-bandpass filter is provided in an optical detection system. In one aspect of the invention, a signal detection area of a two-dimensional detector is divided into plural regions corresponding to wavelength transmission regions of the multi-bandpass filter. An integrated value of the fluorescence spectrum signal is determined in the region including a fluorescence spectrum peak of an analysis sample in the plural regions. The analysis is performed with the integrated value.

    摘要: The object of the present invention is that a dynamic range is extended in an electrophoresis unit and concentration differences among a plurality of samples measured simultaneously are increased.An irradiation time to the samples is adjusted during analysis without changing a sampling time. By shortening the irradiation time, a fluorescence amount of the samples is reduced to cause signal intensity detected by a detector to physically decrease. If the irradiation time is very short (several 100 msec), the irradiation time and fluorescence intensity are in a direct proportional relationship. It is known that, if the irradiation time is reduced to 1/n, the fluorescence intensity, that is, signal intensity to be detected will be 1/n. Thus, for data whose irradiation time is reduced to 1/n during analysis, data obtained by multiplying a substantially measured value by n is used for data analysis as a true value to be originally acquired.

    摘要: An object of the present invention is to provide a capillary electrophoresis apparatus in which simultaneity can be ensured between sensitivity and data acquisition to decrease a pull-up signal while spectral data acquisition is eliminated in each capillary exchange. The invention relates to a capillary electrophoresis apparatus in which capillary position shift is detected in each capillary exchange by detecting a capillary position. A capillary position measuring light source is provided in the capillary electrophoresis apparatus of the invention. The capillary is irradiated with light emitted from the capillary position measuring light source, a capillary image is detected with a two-dimensional detector, and thereby a position deviation of the capillary is determined.

    摘要: The invention aims to improve the spatial resolution in a multi-focus type electrophoresis apparatus that irradiates a capillary array from both ends thereof with laser beams. The invention relates to an electrophoresis apparatus in which capillaries at both ends of a capillary array are irradiated respectively with laser beams, and each of the two laser beams traverses multiple capillaries. In the electrophoresis apparatus, the laser beams are coaxially introduced into the capillary array from the both ends thereof to travel in a direction vertical to axis of each capillary and horizontal to the aligrnent plane of the capillary array; and a λ/4 plate and a polarizer are arranged on the laser beam optical axes. According to the invention, the total width of the incident laser beams is made narrow, generation of pseudo signals is prevented, and an analysis performance is improved.

    摘要: Detection sensitivity is improved by increasing the amount of light of beams that irradiate a sample cell without causing saturation of a detector with ultraviolet beams or visible beams. This spectrophotometer includes a sample cell, which stores a sample to be measured, a visible light source and an ultraviolet light source each for supplying an incident beam that enters the sample, a spectroscope, which disperses a beam that has passed through the sample, an optical detector, which detects beams dispersed from such beam (spectrum), and a dichroic element which reflects or transmits ultraviolet beams from the ultraviolet light source and which transmits or reflects visible beams from the visible light source. Optics are configured such that ultraviolet beams and visible beams that have passed through or have been reflected by the dichroic element enter the sample cell.
