Field amplification stacking

Lichtenberg, J., Verpoorte, E., de Rooij, N.F., Sample preconcentration by field amplification stacking for microchip-based capillary electrophoresis. Electrophoresis 2001, 22(2), 258-271. [Pg.437]

Figure 26-26 Lower trace Sample injected electrokinetically for 2 s without stacking is limited in volume to prevent band broadening. Upper trace With stacking. 15 times more sample could be injected (for 30 s). so the signal is 15 times stronger with no increase in bandwidth. [From V Zhao and C. f. Lurie, pH-Mediated Field Amplification OmCotumn Preconcentration of Anions in Physiological Samples for Capillary Electrophoresis, Anal. Chem. 1999, 71,3985.]...
