Abstract:
An easy and universal wall-jet configuration for microchip CE-ECL detection system was constructed and investigated in this work. Two detection modes of pre-column and post-column were applied to the above system. TPA, tramadol and lidocaine were chosen as model analytes to estimate the system in both modes. The important operational parameters such as the concentration of luminescent reagent and the distance between the separation outlet and the working electrode were optimally obtained and compared for the first time.
