摘要： A novel CEC column preparation method for various forms of CEC separation using selectively or fully packed microchannels with self-assembled silica colloidal particles is disclosed. The method relies on the three dimensional uniform silica colloidal packing through selective regions or whole channels resulting in uniform EOF and reproducibility. The fully packed capillary electrophoretic separation microchip is inherently suited for a handheld system since it exploits uniquely fully packed separation channels to achieve better separation efficiency and stability. The fully packed capillary electrophoretic separation microchip can be easily fabricated using low-cost, rapid manufacturing techniques, and can provide high performance for CEC separation with various chromatographic stationary support packing, functionalized surface of packed beads. The fully packed microchannels with self-assembled silica colloidal particles can be applied for preparation of a built-in submicron filter. Embodiments of the present invention address a significant challenge in the development of disposable CEC microchips, specifically, providing a reliable solution for preparation of the CEC separation column in a device that may be immediately applied for a variety of CEC applications.

摘要： Two types of HgO-modified electrodes are disclosed. The HgO-modified electrode according to the present invention comprises, HgO particles as precursor of mercury, which can be exposed on the surface of the said electrode and then can be reduced electrochemically into micro-droplets of mercury; and electro-conductive material to maintain optimal conductivity of the said modified electrode. In the HgO-modified electrode according to the present invention, built-in mercury precursor, HgO can be utilized feasibly for the generation of the surface mercury droplets by in situ electrochemical treatment or pretreatment without necessity of Hg.sup.2+ solution. The electrode surface can be renewed easily either by a simple polishing process for the bulk-modified electrode type-I or by simple exchange for the screen-printed disposable type modified electrode type-II. So further simplification of anodic stripping analysis process is possible by employing the HgO-modified electrodes according to the present invention.
