一个共振增强多光子电离（REMPI）质谱仪组成的可调谐激光器单元（Nd：YAG泵浦激光器和OPO）和反射质谱仪已经升级，以科普困难的条件下，如振动，温度波动和灰尘，在焚化炉中盛行。在线测量的原料气已在城市垃圾焚烧炉在斯图加特进行。虽然这一系列的测试无法完成，但结果令人鼓舞。他们表明，波长分辨率可以提供有价值的信息以外的固定频率REMPI可获得的。讨论的例子包括干扰物的分离苯胺信号和菲的鉴定。
A resonance enhanced multiphoton ionization (REMPI) mass spectrometer consisting of a tunable laser unit (Nd:YAG pump laser and OPO) and a reflectron mass spectrometer have been upgraded to cope with the difficult conditions such as vibrations, temperature fluctuations and dust, prevailing in an incinerator. On-line measurements of the raw gas have been carried out at the municipal waste incinerator in Stuttgart. Although this test series could not be completed the results are encouraging. They show that wavelength resolution can provide valuable information beyond the one obtainable by fixed frequency REMPI. Examples discussed include separation of interferants to the aniline signal and identification of phenantrene.
