Different from that of nanosecond , benzene phtoionization using femtosecond laser has predominent molecular ion peak with very small percentage of fragments .
苯的飞秒质谱图与纳秒情况不同，分子离子为主，碎片峰很少。

Both IBA and JA standard chemicals showed almost same changes of mass spectrum pattern . Optimum drift voltage for most intensity was 60 V , as drift voltage increased , the intensity of molecular ion peak decreased and the fragment ion peaks shifted to smaller m / z one .
IBA和JA的标准试剂显示了相同的质谱图形变化，在60V时能得到最强分子离子峰，当电压继续升高时分子离子峰的强度逐渐减弱，并出现一些m/z更小的碎片离子峰。
