Size-exclusion chromatography ( SEC ), also known as molecular sieve chromatography, [1] is a chromatographic method in which molecules in solution are separated by their size, and in some cases molecular weight. Sincerely look forward to serving you in the near future. However, due to these adsorbing and catalytic properties, they are useless for analytical purposes of hydrocarbons longer than two carbon atoms. This guideline will help reader to understand about gas dehydration. It can also split gases or liquids in molecular size. In all forms of chromatography one way of identifying eluted substances is by. D. the size of the pores in the sieve material. Molecular sieve adsorbents are crystalline aluminosilicates, known as zeolites. The larger pore size means higher adsorption capacity. The adsorption capacity of a molecular sieve is governed by isotherms (function of temperature and pressure), and once the molecular sieve is saturated with impurity molecules, the equilibrium conditions need to be changed (either temperature or pressure or both) to desorb the impurity and reuse the molecular sieve for adsorption. In addition, our molecular sieves are preactivated and ready to use.
