采用三苯基磺酰氯（TPSC）作为双功能剂，采用三苯基磺酰全氟磺酸（TPA，一种光酸发生器）沉淀法选择性富集全氟烷基磺酸盐，并以TPA的三苯基磺基为基质，采用MALDI-TOF-MS法直接检测全氟磺酸。
Triphenylsulfonium chloride (TPSC) was employed as a bifunctional agent for the selective enrichment of perfluoroalkyl sulfonates by triphenylsulfonium perfluorosulfonic acid (TPA, a photoacid generator) precipitation, and for the direct detection of perfluorosulfonic acid by MALDI-TOF-MS, using the triphensylsulfonium group of TPA as a matrix.
