3. Activated carbon activated carbon adsorbent non-polar, so with silica, alumina factory direct opposite Shin fat, non-polar substances with strong affinity and capacity in water solute exhibit strong adsorption capacity. Solvent polarity decreases, the activated carbon adsorption capacity of the solute decreases. Adsorbing force of the adsorbent is constant, more polar solutes, polar eluent weaker. Operation refers to thin layer chromatography, adsorption of the components of the same depending on the adsorption capacity of the adsorbent, so that the mobile phase (solvent) flows through the stationary phase process (adsorbent), the continuous generation of adsorption, desorption, adsorption and then, then desorption plasticizer dioctyl fat, so as to achieve the purpose of separation of each of the components. No process effluent sample into the stationary phase and the TLC, so people with a marked shift value than substance chromatographic behavior. Rf is a retention time corresponding to the concept, which is the ratio of the sample point is moved in the chromatographic process, the distance between the forefront of the moving distance of the mobile phase. With the same retention time dioctyl fat than the shift value is also determined by the material in the chromatogram of the partition coefficient: R_f = \ frac {V_m + KV_s} where Rf is the ratio shift value, K represents the distribution coefficient chromatography Shin fat price quotes, VsVm represents the volume of the stationary phase and the mobile phase. Based on the theoretical plate number of theoretical plates thermodynamics is the basis of the theory of chromatography, the column plate theory as a fractionation tower components to be separated between the plates move fractionator component molecules in each tray between the stationary phase and the mobile phase in balance, with the flow of the mobile phase, the component molecules constantly moving from one tray to the next tray, and continue to form new balance. A number plate of the column, the more the better the separation. Factory direct Shin fat, Heilongjiang Province Shin fat, dry chemical Xiang Xiang dry by Jinan Chemical Co.
