| 20120032680 | LOW MAGNETIC FIELD RESONANCE SYSTEM - The invention provides a low-field nuclear magnetic resonance system for measuring a magnetic resonance signal of an object. The low-field nuclear magnetic resonance system includes a pre-magnetization module, a uniform magnetic field coil module, a pulse and receiving coil module, a filter amplifier module, a signal acquisition module and a processing module. The pre-magnetization module is used to establish a pre-magnetization field in the object to increase magnetization of the object. The uniform magnetic field coil module is used to change a resonance frequency and background magnetic field intensity of the object during nuclear magnetic resonance measurement by regulating a magnetic field of the coil. The processing module further includes a programming object for controlling timing processing and signal analysis of the measurement process. | 02-09-2012 |
| 20110140688 | Device for Measuring Alternating Current Magnetic Susceptibility and Method of Measuring the Same - A device for measuring alternating current (AC) magnetic susceptibility and the method for measuring the same are provided. The device comprises an AC magnetic susceptibility coil set, a signal capturing unit, and a signal processing unit. The device detects AC magnetic susceptibility signals from under testing particles in the magnetic field with variable AC frequencies, and extracts the AC magnetic susceptibility intensity variation and phase difference and/or the real part and the imaginary part of the AC magnetic susceptibility by the signal processing unit. | 06-16-2011 |
| 20110100891 | DEVICE OF MAGNETICALLY SEPARATING A SAMPLE - Present invention relates to a device magnetically separating a sample. The preferred material for the device is plastic. The device is a cuboid plate, which consists of one or two bottom sides and at least two lateral sides. The bottom side has wells on it to accommodate magnetic elements, and the magnetic element which is suitable to be accommodated into the wells comprising column shape, half-column shape, or half circular column shape magnetic elements. The magnetic element comprises permanent magnet or electromagnet, and the permanent magnet is selected from the group consisting of alnico, samarium cobalt, neodymium iron boron, or magnetic ceramic materials. The magnetic elements can adsorb the magnetic samples in the micro plate. | 05-05-2011 |
