I am trying to find a data set for analysis which is acquired by CE-MS. In case you have one or you know where I can download one, please do not hesitate to let me know!
I recommend to you to check the article "Micellar electrokinetic chromatography-electrospray ionization mass spectrometry employing a volatile surfactant for the analysis of amino acids in human urine". D. Moreno-González, J. Sastre Toraño, L. Gámiz-Gracia, A.M. García-Campaña, G. J. de Jong, G. W. Somsen. Electrophoresis 34 (2013) 2615-2622.
You can find information about the determination of amino acids by CE-MS.
