Abstract
The analysis of analytes is considered one of the most challenges in capillary zone electrophoresis (CE). Fundamental studies on the new green separation of acrylamides by ionic liquid collapse capillary electrophoresis (ILCCE) are presented. The sample solution of the neutral analytes is prepared using ionic liquid 1-butyl-3-methylimidazolium bromide mixed with water as a dissolution solvent in order to increase the conductivity of the sample greater than the BGS. This separation mechanism was used to enrich the sensitivity separation of acrylamides with good resolution. Here, the effect of retention factor of the analyte, conductivity ratio of the sample and BGS, IL concentration in the sample and electrolyte salt concentration in the BGS were examined. A study on the effect of the injection technique to the performance of ILCCE is also presented. The new hyphenation of ILCCE with ionic liquid based ultrasound assisted liquid extraction was successfully applied to the rapid and selective analysis of acrylamide in breads.
