In physics, a mass balance, also called a material balance, is an application of conservation of mass to the analysis of physical systems. By accounting for material entering and leaving a system, mass flows can be identified which might have been unknown, or difficult to measure without this technique. The exact conservation law used in the analysis of the system depends on the context of the problem, but all revolve around mass conservation, i.e., that matter cannot disa… WebMass balance is often part of this investigation and correlates the measured loss of a parent drug to the measured increase in degradation products, or impurities. Given the range of impurities and their chemical and physical properties, a single detection technique may not be adequate to accurately measure all of the degradants.
