Patent number: 10408787Abstract: In an apparatus for analyzing small number of samples, wasteful consumption of a polymer as a separation Medium is suppressed. The apparatus has a configuration provided with a plurality of capillary units each of which can be attached/detached to/from the apparatus, and performs analysis for capillaries after sealing of a polymer by attaching the capillaries by the number in accordance with the number of samples. Since analysis can be performed by using capillaries by the number identical with that of the samples to be analyzed, wasteful polymer is not used in the capillaries not used for the analysis. In addition, the polymer injection mechanism is unnecessary and the polymer is not necessary for maintenance and upon starting of analysis. An electrophoresis apparatus which is small in the size with no polymer injection mechanism, and with low running cost not wastefully consuming the polymer can be provided.Type: GrantFiled: November 30, 2011Date of Patent: September 10, 2019Assignee: HITACHI HIGH-TECHNOLOGIES CORPORATIONInventors: Motohiro Yamazaki, Michiru Fujioka, Takamichi Muramatsu, Takashi Gomi

Patent number: 5976338Abstract: Arranging a pair of temperature control units on both sides of gel 1 and arranging light-transmitting slit 134 on one of the elements, irradiation of an excitation beam over the gel 1 and signal detection are practiced through the slit 134. Introducing dry air onto the slit part, mildew occurrence is prevented on the detecting part. Detecting the power level applied to the gel and calculating the temperature of the temperature control units so that the gel temperature might be a predetermined temperature, on the basis of the detected power level, thereafter carrying out the feedback control of the power level, the gel temperature can be controlled appropriately and strictly during electrophoresis in an automatic fluorescent electrophoresis system, so that high-speed analysis can be done highly reproducibly at a higher voltage applied even by SSCP.Type: GrantFiled: April 22, 1997Date of Patent: November 2, 1999Assignees: Hitachi, Ltd., Hitachi Electronics Engineering Co., Ltd.Inventors: Takeshi Fujita, Masaharu Kiyama, Shin-ichiro Umemura, Takamichi Muramatsu, Yuusuke Miyazaki, Masao Kamahori, Noboru Moriya, Shokichi Matsunami
