I am looking for a HPLC method for the detection of certain Azocoulrants in Dystuff, which may release certain aromatic acids.
Who can help?

If you provided more detail I might be able to help, but I have no idea what it is you want to know from the sparce information provided. Azo dyes are normally detected spectrophotometrically. I do not know what you mean by "release..... acids".
