摘要

Hadamard transform was applied to a microfluidic chip-based capillary electrophoresis system to improve its signal-to-noise level. Multiplexed sample injection was effected by an electrokinetic gated injection approach, employing a 7-bit, 127-step pseudorandom binary sequence. A 5-fold improvement in S/N ratio was achieved, with only 27% increase in analysis time for Cy5 labeled amino acid samples.
