Study on improving operational efficiency using an automatic pretreatment device in the measurement method of exhaust gas mercury.

Study on improving operational efficiency using an automatic pretreatment device in the measurement method of exhaust gas mercury.

Automation of mercury measurement in exhaust gases 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, and the analytical samples are broadly categorized 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 faces challenges such as increased labor involved in the measurement process and the potential for human error due to all tasks being performed manually, which has led to a desire for automation to improve work efficiency. Therefore, to achieve work efficiency and eliminate human errors, we conducted a study on mercury measurement using the automatic addition heating pretreatment device "DEENA" manufactured by BL Tech Co., Ltd.

Study on the decomposition using nitric acid-hydrochloric acid (aqua regia) in the analysis of impurities in iron and steel.

Study on the decomposition using nitric acid-hydrochloric acid (aqua regia) in the analysis of impurities in iron and steel.

[Free Technical Data Available] Successfully automated tasks that were previously done manually! No need for reagent preparation, achieving improved work efficiency!

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; however, 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, but it is labor-intensive and time-consuming, and it generates a significant amount of harmful acid decomposition gases, making it difficult to safely and quickly process multiple samples. Thus, we examined the automatic pretreatment using nitric acid-hydrochloric acid (water) for the analysis of impurities in iron and steel, employing "DEENA," which can perform tasks such as acid addition, stirring, and dilution under PC control in a fully automated manner.

Study on the decomposition using nitric acid in the analysis of Cd and other elements in rice and rice ears.

Study on the decomposition using nitric acid in the analysis of Cd and other elements in rice and rice ears.

[Free Technical Data Available] Fully automated from stirring and heating to filling! Contributes to significant reduction in work time!

This technical document discusses the automatic pretreatment using the nitric acid reflux method for rice (both brown and white rice) and rice ears, utilizing the automatic pretreatment device "DEENA" for processes such as reagent addition and acid decomposition. Regarding cadmium contained in rice, the standard has previously been set at 1 ppm (mg/kg), but in April 2010, a revision was issued concerning the standards for food and additives, changing the standard for cadmium and its compounds in rice (both brown and white) to below 0.4 ppm (mg/kg). In traditional methods, wet digestion typically involves the use of nitric acid, sulfuric acid, or perchloric acid; however, these methods are time-consuming and labor-intensive, making it difficult to process multiple samples quickly. Therefore, we examined the automatic pretreatment using the nitric acid reflux method for rice (both brown and white) and rice ears with "DEENA," which can perform tasks such as acid addition, stirring, and dilution under PC control in a fully automated manner.

Study on the decomposition using hydrofluoric acid and nitric acid in the analysis of impurities in silicon.

Study on the decomposition using hydrofluoric acid and nitric acid in the analysis of impurities in silicon.

Minimize exposure to hydrofluoric acid gas for people and improve the working environment! Also contributes to reducing working hours.

This technical document discusses the automatic pretreatment using hydrofluoric acid and nitric acid for the silicon decomposition (melting) of semiconductor materials and other raw materials, utilizing the automatic pretreatment 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, as this process generates a significant amount of hydrofluoric gas, necessitating precautions against human exposure. Therefore, we examined the automatic pretreatment 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.

Technical Data: Metal Analysis Pretreatment of Rice and Rice Ears Using DEENA2

Fully automated analysis of metals such as cadmium in rice (brown rice and white rice) and rice ears, including the addition of nitric acid and perchloric acid, heating decomposition, cooling, and sample preparation!

Regarding the cadmium contained in rice, the standard limit was previously set at 1 ppm (mg/kg), but in April 2010, a revision was made to the standards for food and additives, lowering the limit for cadmium and its compounds in rice (both brown and white rice) to 0.4 ppm (mg/kg). Traditionally, wet digestion methods using nitric acid, sulfuric acid, or perchloric acid were employed; however, these methods were time-consuming and made it difficult to process multiple samples quickly. Therefore, we examined the automatic pretreatment of rice (both brown and white) and rice ears using the nitric acid reflux method with DEENA2, which allows for fully automated operations such as acid addition, stirring, and dilution under PC control. ■ Acid addition heating pretreatment ■ Reagent addition ■ Cooling ■ Dilution ■ Prevention of human exposure to acid *For more details, please refer to the PDF document or feel free to contact us.

Technical Data: Automatic Pretreatment of DEENA2 Steel with Nitric Acid - Hydrochloric Acid (Aqua Regia)

Technical Data: Automatic Pretreatment of DEENA2 Steel with Nitric Acid - Hydrochloric Acid (Aqua Regia)

A study was conducted on the addition of nitric acid-hydrochloric acid (aqua regia) for the heating decomposition (dissolution) in the analysis of impurities contained in iron and steel.

Steel increases in rigidity when it contains boron and other impurities, but too many impurities can make it brittle. Therefore, managing the impurity content is extremely important in the production of high-quality steel. As an analytical method, the nitric acid-hydrochloric acid (aqua regia) decomposition is commonly performed; however, it is time-consuming and labor-intensive, and generates a significant amount of harmful acid decomposition gases, making it difficult to safely and quickly process multiple samples. To address this, we examined the automatic pretreatment using nitric acid-hydrochloric acid (aqua regia) for impurity analysis in iron and steel, utilizing DEENA2, which can perform tasks such as acid addition, stirring, and dilution control fully automatically via PC control. As a result, we were able to automate tasks that were previously done manually. We also succeeded in reducing human exposure to the acid decomposition gases. ■ Purpose ■ Overview ■ Keywords ■ Equipment Used ■ Analysis Flow ■ Results *For more details, please refer to the PDF document or feel free to contact us.
