Product Overview:
The RA-915F high-frequency Zeeman effect mercury analyzer system analyzes the absorption of 254nm resonant emission lines by mercury atomic vapor. Through Zeeman effect background correction, it can directly analyze the mercury content in flue gas enriched by adsorption tube method. At the same time, it can directly analyze the mercury content in solid waste, waste residue and wastewater samples in coal-fired power plants on site, meeting the requirements of EPA method 30B adsorption tube method and EPA method 7473 combustion heat generation.
