Study Set Content:
measurement of the electrical current when a constant potential is applied
Amperometry
measures solution composition based on the current-potential relationship in an electrochemical cell when the potential is varied
Voltammetry
it is the movement of electrically charged compounds (ions) in a medium resulting to their separation based on their electrical charges when an electric current is applied
Electrophoresis
the separating molecules migrate to an area where the pH is equal to their isoelectric point (a state of having a net charge of zero on a specific pH).
Isoelectric Focusing
it is a process of separation of a chemical mixture into different components based on their physical characteristics and the interactions of molecules with the mobile and stationary phase through a support medium
Chromatography
used in compounds that are volatile or substances that can be converted into gas.
Gas chromatography
analyzes substances that are not readily volatile and use low temp, thus it is suitable for thermolabile compounds
Liquid Chromatography
is based on the fragmentation and ionization of molecules with an appropriate energy source.
Mass Spectrophotometry
is an instrument that detects scintillation using PM tube and counts the electrical impulses produced by the scintillations.
Scintillation Counter
is a separation technique based on electro-osmotic flow, where there is a bulk flow of excess positive ions moving towing the cathode
Capillary Electrophoresis
They make use of biological material that is atransducer in a system that converts biochemical signal to electrical signal
Biosensor
Measures the array of lights or radiant energy absorbed or transmitted.
