The fast atom bombardment mass spectra of 24 alpha-amino acids have been studied. These include the mass spectra as well as the metastable ion MI and collisional activation CA spectra of [M + H]+ and [M - H]- ions. The extent of the common neutral losses as NH3, H2O and CO2H2 in the positive ion spectra is governed by the nature of the side chain. The relationship between the fragmentation behaviour of the negative ions and the presence of particular functional groups is less obvious. Mixtures of amino acids in glycerol show pronounced surface effects.
对24种α-氨基酸的快原子轰击质谱进行了研究。这些研究包括[M + H]+和[M - H]-离子的质谱、亚稳离子MI以及碰撞活化CA谱。正离子谱中常见中性损失（如NH3、H2O和CO2H2）的程度取决于侧链的性质。负离子的碎裂行为与特定官能团的存在之间的关系不太明显。甘油中氨基酸混合物表现出明显的表面效应。
