摘要

RATIONALE: Here hardly ionizable and low molecular weight compounds are detected in negative ion mode by using novel superbasic proton sponges based on 1,8-bisphosphazenylnaphthalene (PN) as MALDI matrices. Among the selected proton sponges, 1,8-bis(trispyrrolidinophosphazenyl) naphthalene (TPPN) has shown the best behaviour as matrix since it allows the direct detection of intact cholesterol without derivatization also in real challenging samples.

机译：理由：在这里，使用基于1,8-双膦腈基萘（PN）的新型超碱性质子海绵作为MALDI基质，在负离子模式下几乎检测不到可电离的低分子量化合物。在所选的质子海绵中，1,8-双（三吡咯烷基膦腈）萘（TPPN）作为基质表现出最好的性能，因为它可以直接检测完整的胆固醇而无需在真实的挑战性样品中衍生化。
