Combined electrophoresis-electrospray interface and method

摘要: A system and method for analyzing molecular constituents of a composition sample includes: forming solution the sample, separating by capillary electrophoresis into an eluent longitudinally separated according to their relative electrophoretic mobilities, electrospraying form charged spray in which have temporal distribution; detecting or collecting accordance with distribution spray. first high-voltage (e.g., 5-100 KVDC) is applied solution. The applying second high voltage ±2-8 between at exit cathode spaced front exit. complete electrical circuit formed conductor directly contacts exit, conduction through sheath electrode discharged annular flow about
