An automated diode laser spectrometer for recording concentrations of trace gases is described. It has been tested for unattended operation in the laboratory and at an atmospheric surveillance station for several months. The sensitivities reached are, e.g., 50 ppt for NO(2) and 300 ppt for NO. In an optical path length of 100 m the lowest extinction measured in unattended operation is ~1.5 x 10(-5) for a measuring time of ~60 s. Recordings of trace gases are shown for urban and rural atmospheric conditions.
本文介绍了一种用于记录痕量气体浓度的自动二极管激光光谱仪。该光谱仪已在实验室和大气监测站进行了数月的无人值守运行测试。所达到的灵敏度例如为：二氧化氮50皮克/立方米，一氧化氮300皮克/立方米。在100米的光程长度下，无人值守运行时测量的最低消光值在测量时间约为60秒时约为1.5×10⁻⁵。文中展示了城市和农村大气条件下痕量气体的记录情况。
