Comminution is the process of exposing materials to stress through collisions and reducing the size of larger solid units into smaller unit masses. Appropriately increasing the elution temperature and time will help the nucleic acid to be released from the magnetic beads. To process photosynthesis, the presence of a catalyst (chlorophyll) is must, whereas in the cellular respiration process the catalysts are not necessary. Solid phase extraction is a process of adsorption, desorption/elution of the target substance on the stationary phase, so the factors that affect the adsorption, desorption/elution will directly affect the extraction efficiency, such as the type of filler, the strength of the elution solvent, and the pH, flow rate, etc. Liquid-Liquid Extraction (LLX) is a mass transfer operation which is used to separate components of a liquid mixture by contacting it with another liquid.
