    Abstract: The present technology provides liquid quality assessment systems and methods for their preparation and use. The systems can include a light source configured to illuminate a liquid sample, a reflecting surface configured to reflect light scattered by the liquid sample, and a detector configured to detect light intensity, wherein the light source illuminates the liquid sample with a first incident light when the reflecting surface is absent; the detector detects a first light scattered by the liquid sample in response to the first incident light; the light source illuminates the liquid sample with a second incident light when the reflecting surface is present; and the detector detects a second light which is a combination of light scattered by the liquid sample in response to the second incident light and light reflected by the reflecting surface of light scattered by the liquid sample in response to the second incident light.

    Abstract: Technologies are generally described for systems and methods for detecting chiral properties of materials and separating materials based on their chiral properties. A chiral vector is constructed from anisotropy properties of a polarization-dependent output signal from a sample. Different types of molecules from the sample can be differentiated based on a magnitude of the chiral vector. Chiral properties of the sample can be detected based on an angle of the chiral vector. The output signal can be a fluorescent emission from the sample and can be used to detect chiral properties of a substantially opaque sample.
