Different techniques are used in a biochemical laboratory to measure various
parameters. For example, a pH meter is used to measure the pH of the sample and
electrochemical cells are used to measure the redox potential. Zeta potential is another
property which can be measured using zeta cells. Chromatography is a technique used
to separate the components of a mixture. Two of the most common chromatography
techniques are HPLC and ion exchange chromatography. HPLC is based on the
interactions of the analytes in stationary as well as mobile phase. Whereas ion
exchange chromatography is based on the interaction of ions and charged site of the
stationary phase.
