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.

This technical document discusses the automatic pre-treatment using hydrofluoric acid and nitric acid for the silicon decomposition (melting) of semiconductor materials and other raw materials, utilizing the automatic pre-treatment device "DEENA" with acid addition and other processes controlled by a PC. When analyzing the silicon (metallic silicon, Si) content and impurities in semiconductor materials, hydrofluoric acid is often used. However, hydrofluoric acid is highly reactive with silicon, requiring careful addition in very small amounts, and during this process, a large amount of hydrofluoric gas is released, necessitating precautions against human exposure. Therefore, we examined the automatic pre-treatment using hydrofluoric acid and nitric acid for the silicon decomposition (melting) of semiconductor materials and other raw materials with DEENA, which can perform tasks such as acid addition, stirring, and measurement automatically under PC control.

This technical document discusses the automatic pretreatment using nitric acid-hydrochloric acid (water) for the analysis of impurities contained in iron and steel, utilizing the automatic pretreatment device "DEENA" for reagent addition and acid decomposition. Steel becomes more rigid when it contains boron and other impurities, but if there are too many impurities, it becomes brittle. Therefore, managing the impurity content is extremely important in the production of high-quality steel. The analysis method commonly used is nitric acid-hydrochloric acid (aqua regia) decomposition; however, this method is labor-intensive and time-consuming, and it generates a significant amount of harmful acid decomposition gases, making it difficult to safely and rapidly process multiple samples. To address this, we examined the automatic pretreatment using nitric acid-hydrochloric acid (water) for the analysis of impurities in iron and steel with "DEENA," which can perform tasks such as acid addition, stirring, and dilution under PC control in a fully automated manner.
