Title: Gradient Elution Electrophoresis and Detectorless
Electrophoresis Apparatus.
Abstract: A microfluidic apparatus and method for performing
electrophoretic separation of compounds. The apparatus comprises: (a) A
first container for containing a sample fluid; (b) a second container
for containing a separation buffer fluid; (c) a channel of a first
length having an inlet end and an outlet end, the inlet end connected
to the first container and the outlet end connected to the second
container; (d) a voltage device electrically connected to the first
container and the second container, the voltage device facilitating
adjustment of the amount of voltage to the first container and the
second container; (e) a controller for controlling the velocity flow of
the sample fluid through the channel from the first container towards
the second container; and (f) a measuring device for measuring the
current through the channel. The method comprises the steps of: (a)
Providing a separation buffer; (b) providing a sample solution in fluid
contact with the separation buffer; (c)
[[Page 22119]]
applying an electric field to the separation buffer; and (d) producing
a variable bulk flow of the separation buffer in a direction
substantially aligned with said electric field. Fluid contact between
the separation buffer and the sample solution is made through a
separation column having a length in the range of from approximately
.01 mm to approximately 5 mm. By the foregoing, compounds can be
sequentially detected and quantified.
