Method and apparatus for automated raw material screening

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.
