Standard Methods For the Examination of Water and Wastewater, 23nd edition 2014). Lack of microbiological quality control simultaneously with physical-chemical tests may contribute to bacterial resistance (1217). H- Since no compendial standards exist, drug release is currently assessed using a variety of methods including sample and separate (SS), continuous flow (CF), dialysis membrane (DM) methods, and a combination The advantages are that the free concentrations is independent of changes in plasma binding and is the pharmacologically active concentration.
