具有相同质荷比的同量异位素离子不能单独通过质谱法(MS)来单独识别,但这种限制可以通过在微滴中使用氢-氘交换(HDX)来克服。由于同量异位素离子可能含有不同数量的可交换位点和不同类型的官能团,因此在液滴喷雾HDX后,每种离子都产生独特的MS光谱图案,而无需MS/MS实验或引入离子迁移率测量。作为这种方法的力量的一个例子,尿代谢谱中的同量异位素离子被识别并用于区分健康个体和患有膀胱癌的个体。
Isobaric ions having the same mass-to-charge ratio cannot be separately identified by mass spectrometry (MS) alone, but this limitation can be overcome by using hydrogen–deuterium exchange (HDX) in microdroplets. Because isobaric ions may contain a varied number of exchangeable sites and different types of functional groups, each one produces a unique MS spectral pattern after droplet spray HDX without the need for MS/MS experiments or introduction of ion mobility measurements. As an example of the power of this approach, isobaric ions in urinary metabolic profiles are identified and used to distinguish between healthy individuals and those having bladder cancer.
