可调谐染料激光器已成功应用于己烷中七种蒽衍生物和五种染料的双光子电离光谱测定。灵敏度取决于激发波长以及摩尔吸收率。蒽、2-甲基蒽和 1,6-二苯基六三烯的检测限低至 20 pg/ml (1 × 10^−10 M)。将染料激光激发的可检测性与氮激光激发的可检测性进行比较。
Tunable dye lasers have been successfully applied to the two-photon ionization spectrometry of seven anthracene derivatives and five dyes in hexane. The sensitivity depended on the excitation wavelength as well as the molar absorptivity. Detection limits for anthracene, 2-methylanthracene and 1,6-diphenylhexatriene were as low as 20 pg/ml (1 × 10^−10 M). The detectability by the dye laser excitation was compared with that by the nitrogen laser excitation.
