QAL 1 certified for continuous, accurate and reliable measurement of total mercury emissions, even in very low concentrations and within complex matrices (SO2, NOx, HCl, etc.) With over 20 years experience, Mercury Instruments (part of ENVEA Group) were the first to develop mercury monitors and mercury analyzers using a dry thermocatalytic method instead of wet chemistry. The SM-4 Mercury Monitor is QAL1 certified and is ready to meet future regulatory requirements (Minamata convention & European directives for thermal power plants and incinerators).
The AULA-254 Gold is a fully automated system for analyzing traces of mercury in aqueous and digested samples In contrast to a typical multi-element AAS the AULA is specially designed for mercury determination. The use of a highly stable low-pressure electrodeless mercury discharge lamp (EDL) in connection with the latest UV detector techniques result in excellent baseline stability and low detection limits. The AULA-254 Gold system meets current regulations, with capacity in reserve to meet more stringent standards.
