ABSTRACT:
A polymer-based microfluidic device and its manufacturing methods. This microfluidic device is suitable for chromatographic and electrophoretic separations in which the detection of the components in the fluid is by means of ultraviolet (UV) spectroscopy. The device further comprises at least one cooling channel adjacent the separation channel, said cooling channel conducting a cooling fluid through the device for removing heat from the the separation channel. At least one section of the separation channel has an increased cross-sectional dimension with respect to other sections of said channel to provide an increased optical path length when the device is used in an ultraviolet detection arrangement.
