本文研究了Ca ~（2+）和Mg ~（2+）螯合剂乙二胺四乙酸（EDTA）二钠盐对碳水化合物挥发/电离的影响。使用模型化合物如麦芽糖（麦芽糖至麦芽七糖）、β-环糊精（β-环糊精、甲基-β-环糊精、七（2，6-二-O-甲基）-β-环糊精、七（2，3，6-三-O-甲基）-β-环糊精和2-羟丙基-β-环糊精）和果聚糖（蔗糖、1-酮糖、nystose和1F-呋喃果糖基nystose）。
The effect of Ca2+(and Mg2+) and the disodium salt of ethylenediaminetetraacetic acid (EDTA), a well known Ca2+(and Mg2+) chelating agent, on the volatilization/ionization of carbohydrates by using electrospray ionization mass spectrometry has been studied. Model compounds such as maltoses (maltose to maltoheptaose), β-cyclodextrins (β-cyclodextrin, methyl-β-cyclodextrin, heptakis(2,6-di-O-methyl)-β-cyclodextrin, heptakis(2,3,6-tri-O-methyl)-β-cyclodextrin, and 2-hydroxypropyl-β-cyclodextrin) and fructans (sucrose, 1-ketose, nystose, and 1F-fructofuranosylnystose) were used.
