通过改变施加在探针电喷雾电离（PESI）和纳米电喷雾电离（nESI）上的高压脉冲宽度，测量了离子信号的时间分布（PESI: 0.12 mm od，尖端直径700 nm的金属针；nESI：金属包覆15 μm id的二氧化硅毛细管）。PESI和nESI（溶液：10−5 M细胞色素c和0.1-1%乙酸在H2O/MeOH（1/1）中）分别在~ 400 μs和5 ms时开始检测离子信号。在10 ~ 5 M细胞色素c溶液中加入10 mM乙酸铵后，信号出现的阈值比酸性溶液长一个数量级，信号强度也较弱。PESI被应用于实际样品，如蛋黄酱、纳豆（发酵大豆）、番茄酱和鲑鱼蛋。在这些样品中观察到有标记的顺序电喷雾。
The temporal profiles of ion signals were measured for probe electrospray ionization (PESI) and nano-electrospray ionization (nESI) by changing the pulse width of the high voltage applied to the emitters (PESI: 0.12 mm o.d. and 700 nm tip diameter metal needle; nESI: metal-coated 15 μm i.d. silica capillary). The ion signals started to be detected at ∼400 μs and 5 ms, respectively, for PESI and nESI (solution: 10−5 M cytochrome c and 0.1–1% acetic acid in H2O/MeOH (1/1)). With the addition of 10 mM ammonium acetate in 10−5 M cytochrome c solution, the threshold for the signal appearance became about one order of magnitude longer with weaker signal intensities than those for acidic solutions. PESI was applied to real samples such as mayonnaise, natto (fermented soybeans), tomato ketchup and salmon eggs. Marked sequential electrospray was observed for these samples.
