Apparatuses and methods for determining the composition of liquid, including a liquid drug (e.g., IV drug) and a liquid drug waste. The apparatuses described herein may determine the identity of one or more drugs in the liquid, the concentration of the drug, and the type of diluent using spectroscopy (such as optical and/or complex immittance spectrographic information). These apparatuses (e.g., devices, systems) and methods are particularly useful for describing the identity and, in some variations, concentration of one or more components of a medical liquid such as intravenous fluid. Also described are methods of recognizing spectroscopic information, e.g., profiles of optical and/or complex immittance spectrograph patterns to determine the composition of a liquid by pattern recognition. |
