Abstract

For the using of space lab, a miniaturized low-power light-emitting diode-induced fluorescence (LED-IF) detector for capillary electrophoresis was constructed and evaluated. In this work, a more efficient exciting light source based on Led was developed and a convenient detect plate was produced to release the problem of focusing LED light into a spot with a diameter less than 100μm.besides these, all closed structure was used to avoid light cluster, and photomultiplier tube was used to be detector.for the reason of power and flexible, the ultra-low Power MCU(MSP430F449) was used to complete signal processing. The system exhibited the result in the concentration range of 1.0×10^-6 to 1×10^-7Mol/L.
