Laser-induced fluorescence (LIF) detection is widely utilized in microfluidic chip due to its high sensitivity and selectivity. In this paper, a LIF detection system for the microscope chip based on a 473 nm laser diode is described. To improve the performance of the detection system, the confocal configuration is adopted in our experiment. Some factors that are important to the signal-to-noise ratio...
A method for the rapid determination of monoamine oxidase (MAO) activity by capillary electrophoresis (CE) has been established. The effect factors including the pH, the concentration of electroosmotic flow modifier (OFM), the salt concentration of running buffer were investigated in detail. The analysis was performed in an uncoated fused-silica capillary with 50 mum id and total length of 70 cm (40...
