The Establishment of On-line Multichannel Raman Spectroscopic Detection System for Capillary Zone Electrophoresis

Abstract

Abstract: An on-line multichannel Raman spectroscopic detection system for capillary electrophoresis was established with an Ar⁺ laser and a cryogenically cooled ICCDas the key elements. Its exterior light system was carefully adjusted to optimize the detection by using benzene and toluene as the probes. On-line electrophoretogram and time series of enhanced Raman spectra of methyl red and methyl orange were acquired at 1 mmol/Land 488 nm laser light for excitation.

Key words: Raman spectroscopy, Capillary electrophoresis, Online coupling, Methyl red, Methyl orange
