20150056098 | SAMPLE ANALYSIS DEVICE AND SAMPLE ANALYSIS METHOD - A problem of a sample analysis device that uses magnetic particles is the difficulty in uniformly capturing magnetic particles, specifically the poor uniformity in the vicinity of channel side walls. This causes poor analysis accuracy and reproducibility. The present invention is intended to provide a means to uniformly capture magnetic particles in the vicinity of channel side walls. Specifically, the present invention provides an analysis device that includes a detection channel with an inlet and an outlet through which a sample liquid containing a specific substance and magnetic particles is flowed in and out of the channel, and magnetic field generating means capable of varying the magnitude of the magnetic field in a predetermined region of the detection channel. The width of the magnet in the detector is greater than the channel width. The detector can improve the analysis accuracy and reproducibility of the analysis device. | 02-26-2015 |

20160097765 | ELECTROCHEMILUMINESCENCE METHOD OF DETECTING AN ANALYTE IN A LIQUID SAMPLE AND ANALYSIS SYSTEM - An electrochemiluminescence method of detecting an analyte in a liquid sample and a corresponding analysis system. An analyte in a liquid sample is detected by first providing a receptacle containing a fluid comprising protein coated magnetic microparticles to a stirring unit. Stirring of the fluid is necessary since the density of the microparticles is usually higher than the density of the buffer fluid. Thus the microparticles tend to deposit on the bottom of the receptacle leading to an aggregation of the microparticles because of weak interactions. To obtain representative measurements a homogeneous distribution of the microparticles in the buffer fluid is necessary to ensure a constant concentration of microparticles for each analysis cycle. It is further necessary to provide disaggregation of the microparticles, which is also realized by stirring the fluid. Stirring is conducted with a rotational frequency that is adapted to the amount of fluid to be stirred. | 04-07-2016 |
20160126058 | Charged-Particle-Beam Device and Specimen Observation Method - An electron microscope has a large depth of focus in comparison with an optical microscope. Thus, information is superimposed on one image in the direction of depth. Therefore, it is necessary to accurately specify the three-dimensional position and density of a structure in a specimen so as to observe the three-dimensional structure of the interior of the specimen by using the electron microscope. Furthermore, a specimen that is observed with the optical microscope on a slide glass is not put into a TEM device of the related art. Thus, performing three-dimensional internal structure observation with the electron microscope on a location that is observed with the optical microscope requires very cumbersome preparation of the specimen. By controlling a vector parameter that defines the interrelationship between a primary charged particle beam and the specimen and by irradiation with the primary charged particle beam with a plurality of different vector parameters, images of transmitted charged particles of the specimen that correspond to each of the vector parameters are obtained. Irradiation with the primary charged particle beam is performed on the specimen that is arranged either directly or through a predetermined member on a detector which detects charged particles transmitted through or scattered by the interior of the specimen. | 05-05-2016 |
