Abstract: A device and a method are provided for isolating a fraction in a biological sample. The fraction is bound to solid phase substrate to define a fraction-bound solid phase substrate. The device includes an input zone for receiving the biological sample therein and a second zone for receiving an isolation fluid therein. A force is provided that is generally perpendicular to gravity. The force is movable between a first position adjacent the input zone and a second position adjacent the isolation zone. The force captures the fraction-bound solid phase substrate and the fraction-bound solid phase substrate moves from the input zone to the isolation zone in response to the force moving from the first position to the second position.

Abstract: In a time of flight mass spectrometer (TOFMS) having a flight space in which ions fly in a loop orbit formed by a plurality of electric sector fields, the present invention provides a simple structure that creates a spiral path by deflecting the ions in the axial direction of the electric fields at every turn of the ions. In a mode of the present invention, the TOFMS has cylindrical electrodes 11 and 12 for creating electric sector fields E1 and E2, between which a parallel pair of planer magnetic poles 15a and 15b are provided. The planer magnetic poles 15a and 15b create a deflecting magnetic field B1 for shifting the ions in the axial direction (Y-direction) of the electric sector fields. The ions experience a Lorenz force once every turn when they pass through the deflecting magnetic field B1. This construction uses only one pair of magnetic poles facing each other across the ion path P to deflect every ion irrespective of its number of turns. There is no need to provide one deflector for each turn of the ions, as in the case of conventional TOFMSs.

Abstract: The improved isotope separator comprises a vacuum vessel, a plasma generator located substantially in the center of the vacuum vessel, an electrode bounded by a hyperboloid of one sheet and a pair of electrodes bounded by a hyperboloid of two sheets, said electrodes being located within the vacuum vessel in such a way as to surround the plasma generator, a power source for supplying said electrodes with a fixed voltage and a pulsating voltage, and magnetic field generating means located outside the vacuum vessel. The apparatus is implemented by a method for isotope separation that achieves high separation factor per stage (process), that enables the process throughput to be increased with ease and which yet is applicable to the isotopic separation of many elements.

Abstract: An ion cyclotron resonance mass spectrometer having a source region and an analyzer region operable in both the standard drift mode and in a pulsed mode which includes ion trapping. Appropriate configurations of applied electrostatic fields permit trapping of ions in the source region of the spectrometer for relatively long periods after which detection is effected by drifting the ions from the source through the analyzer region where their power absorption is measured. The spectrometer may also be operated in the normal mode, thus allowing for the full range of conventional ion cyclotron resonance measurements with the additional capability of examining the variation of ion abundance with time.
