本文提出了一种直接测定大气中NO_2的低压激光激发荧光技术。使用倍频Nd-YAG泵浦激光器和20 s的信号收集时间(每个信号和背景10 s),在实验室条件下计算出450 pptv的检测限。提高灵敏度将是可能的,具有较高的重复率激光和较低的荧光池压力。
A low pressure laser-excited-fluorescence technique (FAGE) for the direct determination of atmospheric NO2 has been developed. Using a frequency-doubled Nd-YAG pump laser and a signal collection time of 20 s (10 s each signal and background) a detection limit of 450 pptv is calculated under laboratory conditions. Improved sensitivities will be possible with a higher repetition rate laser and lower fluorescence cell pressures.
