Demonstration of the possibility of determination of low-molecular analytes (uracil and chromate ions) on a Shimadzu MCE-2010microchip electrophoresis system

The traceable conditions for the detection of uracil and chromate peaks as test model low-molecular analytes using a Shimadzu MCE-2010 Microchip Electrophoresis System were found. It is shown that the MCE-2010 shows high speed of electrophoretic separation and high reproducibility of the peak emergence times and areas. A 7- to 10-fold improvement in the analysis time compared to conventional capillary-zone electrophoretic separation is achieved. The limits of detection of uracil and chromate are 2 and 1 mg/ml, respectively.
