LM of HPLC column packing
Numéro d’image : 11901804
| Light micrograph of resin beads used in High Pressure Liquid Chromatography (HPLC),a technique for separating closely-related components from a sample solution. In this case the beads are coated with a hydophobic,waxy substance which has a long molecular backbone of 18 carbon atoms. The beads are packed into a column,usually a steel tube,through which the sample is pumped under pressure. Each component experiences an attraction to the beads which depends on its hydrophobic/hydrophilic properties,hence they emerge from the bottom of the column at different rates.
