Commonly used chromatographic techniques are identified through the nature of the stationary and mobile phases used, the method for passing the mobile phase through the apparatus, and how separated components are identified. Get Latest Price from the seller. ,.4 WDnoCY&n PK ! In paper chromatography the stationary phase is paper and the mobile phase is generally some liquid that will dissolve the analyte and wet the paper, often water or an aqueous solution. Why is softening the cork important during boring? The gases are passed through a long, narrow (and most often, coiled) tube either packed with a porous stationary phase or whose inner walls are coated with a stationary phase, and the analyte components are detected as they emerge from the far end of the tube. Assessing the risks What are the details of the activity to be undertaken? While the water is reaching the desired temperature, get potato and bore out a cylinder with cork borer.
