Coupling Capillary Electrophoresis and Ion Mobility Spectrometry via Electrospray Interface: a Preliminary Study
To combine capillary electrophoresis (CE) and ion mobility spectrometry (IMS) to setup CE-IMS coupling technique, an effective sheathless electrospray interface was developed in the paper. The capillary was rotated on a fixed connector and tapered by manual gridding on the emery paper to obtain tapered capillary tip with the polyimided layer, geometric symmetry. And then the tapered tip was coated with nickel by a simple electrode-less plating procedure to be electrically conductively, so as to generate the electrospray on the tip. Finanlly, three different ways were evaluated for coupling CE with IMS, and get the relatively more effective interface to combine CE and IMS.
