基质辅助激光解吸离子化飞行时间质谱(MALDI-TOF-MS)是一种软电离质谱,通过将微量样品与基质混合形成共结晶,在激光照射下将样品离子化后进入飞行时间质量分析器进行检测.MALDI 具有样品制备简单、信噪比高、耐盐性好等优点,已经广泛应用于生物大分子及聚合物、有机小分子的定性分析.

近年来,我国饮用水异味事件频发,受到了全社会广泛的关注.根据异味轮廓图,异味种类可分为八类,即土霉味、氯味、草味、沼气味、硫味、鱼腥味、药味及化学品味等.其中,2-甲基异莰醇(MIB)、2-异丙基-3-甲氧基吡嗪(IPMP)、2,4,6-三氯苯甲醚(2,4,6-TCAS)、2-甲氧基-3-异丁基吡嗪(IBMP)和土臭素(GSM)是最常见的土霉味物质,其主要由湖库中藻类爆发而产生[1].
