激光电离飞行时间质谱已被应用于研究三过氧化三丙酮（TATP），一种简易炸药。使用纳秒（5 ns）和飞秒（130 fs）激光脉冲在两个时间制度的波长依赖的质谱。我们发现，当采用飞秒激光脉冲时，两种时间机制之间的主要区别在于对母分子离子的检测。(C)2006 Elsevier B.V.保留所有权利。
Laser ionization time-of-flight mass spectrometry has been applied to the study of triacetone triperoxide (TATP), an improvised explosive. Wavelength dependent mass spectra in two time regimes were acquired using nanosecond (5 ns) and femtosecond (130 fs) laser pulses. We find the major difference between the two time regimes to be the detection of the parent molecular ion when femtosecond laser pulses are employed. (C) 2006 Elsevier B.V. All rights reserved.
