摘要： The present invention provides a capillary electrophoresis apparatus in which a capillary is easily attached to and detached from a migration medium filling unit without mixing impurities into the capillary. Mixture of impurities such as dust is also prevented when a capillary negative-electrode end is brought into contact with a sample stored in a vessel. Furthermore, temperature control is efficiently performed in the capillary. In the capillary electrophoresis apparatus, the whole of capillary array can be supported by grasping a grip portion by hand. A migration medium filling mechanism includes a slide mechanism which moves a polymer block with respect to a capillary head. The capillary electrophoresis apparatus includes a vessel in which a sample and a buffer can simultaneously be stored. Temperatures of the capillary and an irradiation and detection unit are controlled by a temperature control function provided in a thermostatic device.

摘要： In a case where the temperature of capillaries cannot be controlled rapidly in accordance with the change of the amount of heat generated from the capillaries, the phoretic speed of the sample is not controlled constant to lower the analyzing performance for the sample. This invention intends to stabilize the electrophoretic speed. The surface of a substrate on which a plurality of capillaries are arranged is in contact with a member capable of temperature control thereby controlling the temperature of the capillaries. Since a member capable of controlling the temperature and the capillaries are in direct contact with each other according to the invention, the temperature of the capillary can be controlled rapidly at a high accuracy, so that electrophoretic speed is stabilized.

摘要： The present invention relates to detection of an emission spectrum by irradiating excitation light onto a plurality of electrophoretic paths and dispersing fluorescent light output from the electrophoretic paths in a direction approximately vertical to an electrophoretic direction. According to the invention, since an emission spectrum to be detected does not substantially change over time, it becomes possible to make observed emission spectrums completely correspond to various fluorescent dyes or various bases.

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.

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.

摘要翻译： 本发明的目的是在电泳单元中扩展动态范围，同时增加多个样本之间的浓度差。 在分析过程中调整样品的照射时间，而不改变采样时间。 通过缩短照射时间，减少样品的荧光量，使得由检测器检测出的信号强度物理降低。 如果照射时间非常短（几百毫秒），照射时间和荧光强度成正比关系。 已知如果照射时间减少到1 / n，则荧光强度即被检测信号强度为1 / n。 因此，对于在分析期间其照射时间减少到1 / n的数据，将通过将基本上测量的值乘以n获得的数据用作数据分析作为最初获取的真实值。
