Purifying chemicals. The scientist is using an Isco sq 16x open access purification system. This provides a means of purifying chemicals in the laboratory rather than sending samples to a central laboratory for processing. This machine is purifying polymers using a chromatography technique. The sample is passed through a column, and separates out into its components as the molecules travel through the column at different rates. This allows impurities to be removed.
