Find out the wonders of capillary electrophoresis!! Located in
Singapore, our strength are in the area of capillary electrophoresis (CE), Micellar
electrokinetic chromatography, microchip/mircochannel capillary electrophoresis (CE),
microchip capillary electrophoresis, lab-chip/lab-on-a-chip and other related fields. Our
research workers are delighted to channel their creative minds to innovate on better
instruments for analytical purposes.
Background of Capillary electrophoresis (CE)
Capillary electrophoresis (CE) is a modern variant of electrophoresis in
instrumentation. Electrophoresis is a separation technique based on the differential
migration of electrically charged molecules or particles in a conductive liquid-based
medium under the influence of an electric field. Distinctive feature of capillary
electrophoresis is the use of small capillaries which have large ratios of area-to-volume.
Efficient heat dissipation allows the use of high voltage for the separation. General
advantages of capillary electrophoresis include high separation efficiency, short analysis
time, low sample and reagent consumption, and easy automation.
The operational modes of capillary electrophoresis include:
Capillary zone electrophoresis (CZE)
Capillary gel electrophoresis (CGE)
Micellar electrokinetic capillary chromatography (MEKC or MECC)
Capillary electrochromatography (CEC)
Capillary isotachophoresis (CITP)
Affinity capillary electrophoresis (ACE)
Capillary isoelectric focusing (CIEF)
All the capillary electrophoresis modes above can share the same instrumental setup,
such as our portable CE system (Model CE-P1). Another format of capillary electrophoresis
is performed on a microchip, namely microchip capillary electrophoresis. In addition, a
lab-on-a-chip system can be used for accomplishing more complicate analytical tasks
requiring highly integrated instrumentation.
Capillary electrophoresis, as an modern analytical technique, has been applied for
inorganic ion analysis, environmental monitoring, water analysis, clinical analysis, food
analysis, drug screening and biochemical analysis.
