研制了一台用于二恶英分析的单泵超声射流/多光子电离/质谱仪（SSJ/MPI/MS）。利用光学参量振荡器（OPO）进行激发和电离，获得了氯苯和二苯并呋喃的质谱和多光子电离光谱。氯苯（S / N = 3）的检测限为0.3ppb，其对应于0.1pg的绝对量。旋转温度为35 K。这种略微高的温度可以归因于仪器中使用的长喷嘴喉部。
A compact supersonic jet/multiphoton ionization/mass spectrometer (SSJ/MPI/MS) equipped with a single pump system was developed for use in the analysis of dioxin. A mass spectrum and multiphoton ionization spectrum were obtained for chlorobenzene and dibenzofuran using an optical parametric oscillator (OPO) for excitation and subsequent ionization. The detection limit for chlorobenzene ( S / N = 3) was 0.3 ppb, which corresponds to an absolute amount of 0.1 pg. The rotational temperature was 35 K. This slightly high temperature can be attributed to the long nozzle throat used in the instrument.
