The analyzer RGA/m is presented for measurements of mercury vapor concentrations in ambient air. It is based on a method of the atomic absorption spectroscopy. The emission source used in the analyzer is a low-pressure capillary lamp filled with mercury of natural isotope mixture. The transverse Zeeman Effect is used to split emission line into fine components. The several features of this analyzer are demonstrated.
Description is presented of a portable mercury gas analyzer operating on the differential absorption method. A gas discharge capillary lamp filled with natural mercury is used as a radiation source. Transverse Zeeman effect is used to get two wavelengths.
