1. method that is a kind of while detecting 40 kinds of amino acid in dry blood cake, blood and urine, it is characterised in that:

  • Using HPLC-40 kinds of amino acid of MS/MS methods pair are detected, and the mobile phase A of liquid chromatogram is the water containing ten trifluoro enanthic acid, and B is containing 13The acetonitrile of fluorine enanthic acid, gradient elution;

    Mass spectrum uses the polyion reaction monitoring pattern of positive ionization electrospray ionization;

    40 kinds of amino acid are:

    Glycine, alanine, Beta-alanine, sarcosine, alpha-amido n-butyric acie, γ

    -aminobutyric acid, silkPropylhomoserin, proline, valine, threonine, taurine, leucine, isoleucine, 5-ALA, ornithine, asparagus fern acylAmine, aspartic acid, glutamine, glutamic acid, lysine, methionine, histidine, phenylalanine, arginine, citrulling, junket ammoniaAcid, carnosine, tryptophan, homocysteine, ethanol amine, kreatinin, guanidine acetate, alloisoleucine, creatine, alpha-amido second twoAcid, 3-Methyl histidine, 1-Methyl histidine, homoserine, argininosuccinic acid, 3- hydroxy-prolines.
