Abstract
Systems and methods include a method for determining the purity of a sample. An image capture is performed of a reference material having a known purity and an unknown material having an unknown purity for which a priori information is known, including that the reference material and the unknown material have a same material type. An image comparison of the reference material and the unknown material is performed to determine a color difference vector between an image of the reference material and an image of the unknown material. A purity of the unknown material is determined using the color difference vector.
