用飞秒激光作为电离源电离被分析物分子，用长（42厘米）和短（6.4厘米）飞行管的双型飞行时间质谱仪进行测量。使用模拟信号数字化仪和时间相关单离子计数系统测量信号，并通过比较两种仪器获得的数据来评估性能。短质谱计的质量分辨率为450，可用于香精中致敏物质的痕量分析。
An analyte molecule was ionized using a femtosecond laser as the ionization source and was measured by a twin-type time-of-flight mass spectrometer with long (42 cm) and short (6.4 cm) flight tubes. The signal was measured using an analog signal digitizer and a time-correlated single ion counting system, and performance was evaluated by comparing data obtained from both instruments. The short mass spectrometer had a mass resolution of 450 and was used in the trace analysis of allergenic substances in a fragrance.
