Study on improving work efficiency using an automatic pretreatment device in the measurement method for mercury in exhaust gas.
Automation of mercury measurement in exhaust gas for improved operational efficiency. Reduction of human error as well.
This technical document discusses the efficiency improvements in the measurement of mercury in exhaust gases using the automatic pretreatment device "DEENA." The method for measuring mercury in exhaust gases is defined in the Ministry of the Environment's Notification No. 94 of 2016, where the analytical samples are broadly classified into "gaseous mercury," which is collected in an absorbent solution, and "particulate mercury," which is collected on a cylindrical filter paper. This mercury measurement method has increased labor requirements, and since all tasks are performed manually, there is a risk of human error, making automation for efficiency improvements desirable. Therefore, to enhance work efficiency and eliminate human errors, we conducted a study on mercury measurement using the automatic acid and other additive heating pretreatment device "DEENA" manufactured by BL Tech Co., Ltd.

basic information
【What is DEENA】 It is a device that can perform the entire process from the addition of reagents, stirring, heating, cooling, to the addition of internal standard reagents and dilution, all automatically. According to reports by Doda et al., very good recovery rates were achieved in the addition and recovery tests of heavy metals (Al, Fe, Mn, Ba, Cd, Cr, Cu, Pb, Zn) during the decomposition treatment of water samples using DEENA. Additionally, it has been confirmed that the syringe module also has a high recovery rate and can be applied to the addition of internal standard solutions. *For more details, please refer to the PDF document or feel free to contact us.
