A new method for the mass calibration of the matrix-assisted laser desorption/ionization-mass spectrometry spectrum is introduced. This method achieves the same accuracy as that of internal calibration but without its drawbacks. The interference and signal suppression by calibration standard are avoided, and a pure/clean sample spectrum is obtained. No prior knowledge about the sample quantity is required for the calibration. The effectiveness of the method is demonstrated with protein identification data.
介绍了一种用于基质辅助激光解吸/电离质谱谱图质量校准的新方法。该方法实现了与内标校准相同的准确度,但没有其缺点。避免了校准标准物的干扰和信号抑制,获得了纯净的样品谱图。校准不需要关于样品量的先验知识。通过蛋白质鉴定数据证明了该方法的有效性。
