The possibility of increasing the sensitivity of the mercury vapor analyzer in ambient air using a capillary lamp with a natural mercury isotopic mixture in the presence of the transverse Zeeman effect as a radiation source has been experimentally studied. Lamp radiation is stabilized by separate control of temperatures of the capillary and lamp bulb. The obtained sensitivity of the analyzer reached 14 ng/m³ during more than 40 min.

基于塞曼原子吸收光谱法的汞蒸气分析仪中汞毛细管灯辐射的稳定特性

实验研究了使用带有天然汞同位素混合物的毛细管灯在横向塞曼效应作为辐射源的情况下提高汞蒸气分析仪在环境空气中的灵敏度的可能性。通过分别控制毛细管和灯泡的温度来稳定灯泡的辐射。在超过40分钟的时间内，分析仪获得的灵敏度达到14 ng / m ³。
