What kind of anion exchange resin does vc and vc ether use? Ion Exchange Chromatography (IEC) is the stationary phase of Ion Exchange agent,A chromatography method based on the difference in the binding force between the component ions in the mobile phase and the equilibrium ions on the exchange agent for reversible exchange.On 1848,Thompson et al found ion exchange during the study of exchange of alkaline substances in soil.In the 1940s S,Polystyrene ion exchange resin with stable exchange properties has emerged.On 1950s,Ion exchange chromatography enters the field of biochemistry,Applied to the analysis of amino acids.At present, ion exchange chromatography is still a common chromatography method in the field of biochemistry,It is widely used in the separation and purification of various biochemical substances such as amino acids, proteins, sugars, nucleotide, etc.The commonly used ion exchange agents are: Ion exchange cellulose, ion exchange
The tap water is turbid. can it be clarified with a water purifier? The tap water is turbid and can be clarified with a water purifier.If the urban and rural water quality is turbid, the water purifier with the dual functions of coarse filtration and fine filtration should be selected.1. the structure of the water purifier is different, and the water purification effect is different. Generally speaking, the first-class filter water purifier is simple in structure, mainly activated carbon, and its filtration capacity is limited. it can only be used for coarse filtration. the filtered water is best heated and boiled for drinking.2. multi-stage filter water purifier. This water purifier has two levels of coarse filtration and a set of fine filtration, and the fine filtration is mostly made of hollow fiber filter elements. the filtered water can be directly drunk. Multi-Stage filter water purifier is currently used more in the family.3. the filter water purifier with ultra-filtration NF membrane consists
