  • Method for analyzing intact capsules and tablets by near-infrared reflectance spectrometry
    Patent number: 4893253
    Abstract: The BEAST method, when used in conjunction with NIRS data at as few as one or two wavelengths, is able to quickly detect a wide variety of adulterants in capsules, obviating the need to open them for analysis. The ability of this technique to detect the absence of components that should be present as well as the presence of components that should be absent enables it even to signal the presence of adulterants that have no near-infrared absorption.
