摘要： A method and a device for tuning a HF source, which oscillates at a basic frequency, to a narrow-band component, in particular for tuning a microwave source 61 of an electron spin resonance spectrometer to a resonator 62. In order to mutually tune the resonance frequency F.sub.R of the resonator 62 and the basic frequency f.sub.O of the source 61, the output signal of the source 61 is mixed in a mixer 64 with a sweep signal of an oscillator 65. The behavior of the resonator 62 is observed on a visual display unit 67, via a detector 68, in the form of what is called a "mode curve", and the source 61 is re-tuned so that two dips in the mode curve are brought into coincidence.

摘要： A method and an apparatus are disclosed for detecting an atomic structure of a sample along a surface thereof. The method comprises arranging the sample in a constant magnetic field (B.sub.0) of predetermined field strength and high homogeneity and irradiating a high-frequency magnetic field (B.sub.1) of a predetermined frequency on the sample, wherein the fields (B.sub.0) and (B.sub.1) are oriented perpendicularly to each other. The method further comprises providing a force-sensitive sensor having a paramagnetic tip comprising a paramagnetic material. The sensor is placed in close vicinity to the sample such that the paramagnetic tip is in atomic interaction with the sample surface which means that the distance between the tip and the surface is in the order of between 1 and 10 .ANG.. The predetermined field strength and the predetermined frequency are set such that electron paramagnetic resonance (EPR) is excited within the tip paramagnetic material. The paramagnetic tip is then displaced parallel to the sample surface for mapping predetermined points on the sample surface. During displacing the tip the force exerted on the tip by a local inhomogeneous magnetic field (B.sub.loc) caused by atomic magnetic moments (m.sub.e,k) of the sample is measured.

摘要： An apparatus for determining a quantitative property of a sample substance by means of magnetic resonance is disclosed. The apparatus comprises a conveyor for conveying sample containers containing the sample substance through a measuring station. The measuring station comprises a magnet system for generating a constant magnetic field of high homogeneity. The measuring station, further, comprises a probe head adapted for letting sample containers be conveyed therethrough and for generating a high frequency magnetic field. A magnetic resonance measuring unit determines the quantitative property of the sample substance contained in the probe head. The probe head excites and detects, resp., the magnetic resonance essentially only within that section of the sample container which contains the sample substance. The probe head comprises a split-ring resonator which, as seen in a conveying direction of the conveyor, has a passage cross-section for letting run the sample containers therethrough. The high frequency magnetic field is generated essentially only in an area of the passage cross-section through which the sample containers run during conveying.

摘要： A method and an apparatus for investigating the imperishability of n liquid foodstuffs using electron spin resonance (ESR) exposes samples of the foodstuffs to an elevated temperature for an extended time-period. At predetermined intervals during the period, the intensity of an ESR signal of each sample is measured and plotted vs. time in a diagram for that sample. The time of a superproportional increase in intensity is detected for each foodstuff. The number n of different foodstuffs is determined by dividing the predetermined interval by the measurement time. The n samples are investigated simultaneously by sequentially cycling the n samples through a common sample vessel. Each time, the intensity of the ESR signal of the sample is measured and then plotted in a diagram unique to that foodstuff. The sequence of foodstuffs are cycled through the sample vessel until a predetermined number m of measuring points per foodstuff has been attained.
