This study develops a novel electrophoresis
microfluidic device featuring a conventional cross-form
injection system and an expansion chamber located at
the inlet of the separation channel. The combined
injection system / expansion chamber arrangement is
designed to deliver a high-quality sample band into the
separation channel such that the detection performance
of the device is enhanced. The results indicate that an
expansion chamber with an expansion ratio of 2.5 and
an expansion length of 500 μm delivers a sample plug
with the correct shape and orientation. The novel
microfluidic device developed in this study has an
exciting potential for use in high-performance,
high-throughput chemical analysis applications and in
many other applications throughout the field of
micro-total-analysis systems(μ-TAS).
