For example, if the run buffer is 20 mA4 phosphate, it may be appropriate to rinse with 100 mk! It is not obvious whether a rinse stepshould be included in a particular method. Generally, it is better to include one to prevent potential problems. If the sample is an uncomplicated matrix, then it may be possible to avoid a rinse step. During method development, the rinse step should be optimized to give a good migration time precision. Having established the optimum buffer conditions, ten replicate analyses should be conducted of a typical sample solution using the selected rinse step(s) between injections.

Falter or centrifuge the sample tf requu-ed, and transfer the sample solution to autosampler vials 5. Place the vials contammg the electrolyte, rinse solution(s), calrbrations, blank, and samples mto the approprtate positions on the autosampler. 6 Perform a test injection of a test mixture to confirm the system 1soperating correctly, 7. Analyze the samples under the conditions specified m the method. A typical sequence will contain analysis of a solution of the dissolving solvent, and a number of injections of the calibration solutions and sample solutions.
