About the sample preparation method for selenium (Se) analysis in JIS K 0102.

Investigation using the fully automated acid addition heating decomposition pretreatment device DEENA2! Automation and efficiency of pretreatment processes such as nitric acid and sulfuric acid.

The method for the pretreatment of selenium specified in the industrial wastewater testing method (JIS K 0102) involves complex reagent addition operations during acid digestion, making it very labor-intensive. Additionally, the use of acidic reagents such as nitric acid and sulfuric acid poses exposure risks to humans, making the analysis hazardous. Therefore, using the automated pretreatment device DEENA2 for acid addition and other processes, we automated the sample pretreatment for atomic absorption spectrometry, ICP, and ICP/MS. [Summary] ■ Conducted a study on the pretreatment of selenium (Se) in wastewater analysis ■ Used DEENA2 ■ Performed digestion using nitric acid, sulfuric acid, etc. ■ Considered automation *For more details, please download the PDF or feel free to contact us.
