Hydrophobic interaction chromatography (HIC): HIC separates proteins based mostly on their own hydrophobic Attributes at substantial salt concentrations.
An HPLC instrument has 4 significant parts: a pump to provide the cell phase, an autosampler to inject the sample, a stationary stage column to
Chemical Oxygen Demand is determined by acidifying the drinking water sample, and afterwards heating it to one hundred fifty?C for 2 hrs. This heat brings about the sample being oxidized. Despite having warmth, this reaction is not going to take place spontaneously, it requires a catalyst.
