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.
