    摘要: An automated screening device that performs standardized system suitability tests and evaluations and measures components of a submitted sample to assist in the quality control screening of raw materials, ingredients, pharmaceuticals, chemicals, polymers, food products, petroleum and many other materials. After determining the performance suitability of an NMR spectrometer, the system permits samples to be submitted for screening. An NMR spectrum of a sample is acquired and a qualitative analysis unit identifies at least one reference NMR spectrum corresponding a compound present in the sample and a quantitative analysis unit integrates relative signal intensity signals of the sample spectrum in regions of peak intensity in the one reference NMR spectrum and compares integration results to a number of atoms in each region in order to confirm identification of the compound.

    摘要: The invention refers to a method of resonance spectroscopy for the analysis of statistical properties of samples, comprising the following steps: a) recording of a complex resonance frequency spectrum of each sample by means of phase sensitive quadrature detection; b) numerical differentiation of the recorded complex resonance frequency spectra versus frequency; c) determination of the absolute value of each differentiated complex resonance frequency spectrum (=fingerprint); d) allocation of each fingerprint to a point of a multidimensional point set; and e) performing a pattern analysis of the generated points for characterizing the statistical properties of the samples. The inventive method tolerates unintended variances of measurement in the recorded resonance frequency spectra, in particular caused by phase errors, and allows reliable automated spectral analysis.
