My customer is trying to analyze anions in water soluble paint by using Capillary Electrophoresis technique. She has some difficulties related to the sample preparation or suitable technique. Do you have any suggestion for this kind of sample preparation or suitable technique to anaylze this kind of analyte in water soluble paint sample.
Using the Agilent Application Finder, Application Finder | Agilent I tried to find something similar to what you are requesting: https://www.agilent.com/cs/library/applications/5990-3386EN.pdf - "Sample preparation consisted simply of diluting the sample 1:200 with water."
Hope this helps a little bit, if not, don't hesitate to write back. Thanks!
