Flow through packed beds
WebDec 17, 2024 · 1 INTRODUCTION. Packed-bed column liquid chromatography constitutes the main separation step for the purification of products in the bioprocessing industry. 1 Its basic principle relies on the flow of a mobile phase containing product and impurities through a packed bed composed of porous particles (the stationary phase). The … WebAbstract. There are two quite different types of porous media: Packed beds: These include rock piles, sand filters, soil in flower pots, cigarettes, and absorption columns. For good gas-liquid contacting, absorption columns are usually packed with specially shaped ceramic, plastic, or metal objects such as rings and saddles which have both a ...
