Electrolyte systems in CE corresponds both to the stationary phase and to the eluting solution in high performance liquid chromatography (HPLC). Features worthy of note for electrolytes in CE are as follows; (1) sufficient buffering capacity to suppress pH shift caused by migration of ions in the electrolyte, (2) low

偶然

Detectiony low. Since the capillary diameter in CE is less than 100μm and the entire volume of the capillary in most cases is less than 10 μl, the optical path should be short enough to detect analyte zones without loss of separation efficiency. Consequently, the detection limit is between 1 and 0.1 ppm with
