MALDI MASS ANALYSIS METHOD OF INORGANIC ION WITH DIPICOLINIC ACID AND ANALOGUE THEREOF AS MATRIX, AND THE MATRIX

摘要

PROBLEM TO BE SOLVED: To provide a MALDI mass analysis method for extremely easily quantifying metal ions while using 2,6-pyridinedicarboxylic acid (dipicolinic acid) which has high adsorbability to strontium and absorbs laser light of a mass analyzer on the market and an analogue thereof, and a matrix used for the MALDI mass analysis method, containing 2,6-pyridinedicarboxylic acid (dipicolinic acid) and the analogue thereof.;SOLUTION: According to a MALDI mass analysis method, 2,6-pyridinedicarboxylic acid (dipicolinic acid) is used as a matrix. A specimen to be analyzed is a metal ion containing an alkali metal and an alkaline earth metal.;COPYRIGHT: (C)2013,JPO&INPIT
