About the pretreatment method for arsenic (As) analysis in JIS K 0102.

Utilize for labor shortages and work style reforms! Automation and efficiency improvement of pretreatment processes for nitric acid and sulfuric acid.

The pre-treatment method for arsenic specified in the industrial wastewater testing method (JIS K 0102) involves complicated reagent addition operations during acid digestion, making it very labor-intensive. Additionally, the use of acid reagents such as nitric acid and sulfuric acid poses exposure risks to humans, making the analysis hazardous. Therefore, using the automated pre-treatment device DEENA2 for acid addition and other processes, we automated the sample pre-treatment for atomic absorption spectrometry, ICP, and ICP/MS. [Summary] - Conducted a study on the pre-treatment of arsenic (As) 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.*
