ADDITIVES FOR MEASURING THE MOLECULAR WEIGHT OF A PHOSPHORIC ACID MONOESTER BY MASS SPECTROSCOPY |
摘要 |
<p>The present invention provides a method for confirming existence of a phosphoric acid monoester compound (peptide, saccharine and the like) and easily identifying the molecular weight thereof even among biological samples including a plurality of compounds, and an additive for a mass spectrometry used for the method. In the method according to the present invention, a complex compound exhibiting extremely high coordination ability to a phosphoric acid monoester group and configured of single kind of zinc isotopes is used to obtain a plurality of mass spectrum data, and then the data are compared. <IMAGE></p> |
