2022/06/15 · Chemical oxygen demand (COD) is an indirect measurement of the amount of organic matter in a sample. With this test, you can measure virtually all organic compounds that can be digested by a digestion reagent. COD contrasts with biochemical oxygen demand (BOD), which relies on the use of microorganisms to break down the organic material in the
SAMPLE TEST RESULTS – STRESSED SAMPLE Adalimumab sample was stressed by pH change from 6.0 to 1.0 to 10.0 and back to 6.0 and then incubated at 60 °C for 60 min. A volume of 100 µL of both unstressed and stressed adalimumab was injected onto an HPLC system to characterize the difference in HMWs percentage.
