What does MEKC stand for?
[top] Micellar Electrokinetic Chromatography. This is a technique that utilizes both capillary electrophoresis and the chromatographic nature of hydrophobic molecules. 18. I have been using an SDS buffer for MEKC in the past and have found that migration times increase with day to day runs. Eventually, I have to replace the capillary. What kind of Day to Day and Run to Run reproducibility of migration times can I expect with CElixir-SDS ? [top] Properly using the CElixir-SDS kit for MEKC, you will find much improved run to run and day to day reproducibility over many standard SDS methods. You can usually expect below 1% RSD of migration times for the first N runs within the first day. The next day, you can expect approcimately 0.3%. For intraday RSD you should see below 3% for the first two – three days; then the RSD will improve and stabilize to better than 1%.
