Stabilization Features of Mercury Capillary Lamp Radiation in the Mercury Vapor Analyzer Based on Zeeman Atomic Absorption Spectroscopy

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 co...

Summary: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/m 3 during more than 40 min.
