[PFA Acid Cleaning Bottle Pack Introduction Case] Comprehensive Chemical Manufacturer Company A

No pre-treatment required for ultra-trace analysis! Introducing a case study on PFA acid-washed bottle packs. We are also developing containers (bottles) for EUV applications.

Company A, a comprehensive chemical manufacturer with numerous production bases not only in Japan but also overseas, is developing new chemicals used in the front-end manufacturing of semiconductor components. The products under development by the company are chemicals that are easily affected by metal ions, leading to discrepancies in chemical evaluation data with customers, which hindered the development process. To address this, they introduced a "PFA acid-washing bottle pack" with stable metal ion levels ranging from 30 ppt to 1 ppt. By conducting chemical evaluation work with a common evaluation container with customers, it became possible to proceed with the work confidently without fluctuations in evaluation data. [Case Study] <Problems> - Due to the susceptibility of the chemicals to metal ion influence, attempts at in-house acid washing did not result in stable high purity ion values. - Discrepancies in chemical evaluation data with customers hindered the development process. <Solution> - Adoption of the PFA acid-washing bottle pack (10 types). <Result/Effect> - Chemicals can be immediately used for evaluation work after opening. - Stable metal ion elution levels around 10 ppt for 20 target metal ions. *For more details, please refer to the PDF document or feel free to contact us.
