Fig. 2From: Assessment of drug content uniformity of atropine sulfate triturate by liquid chromatography–tandem mass spectrometry, X-ray powder diffraction, and Raman chemical imagingRaman chemical imaging of 10-, 100-, and 1000-fold triturates prepared by the wet or dry mixing method (10 mm × 10 mm, 42.5 μm spatial resolution). Panels a, b, and c represent the image of 10-, 100-, and 1000-fold triturates by the wet mixing, respectively. Panels d, e, and f represent the image of 10-, 100-, and 1000-fold triturates by the dry mixing, respectively. Red and green areas indicate atropine sulfate and lactose hydrate, respectivelyBack to article page
