Le 14 et 15 mars dernier, Particle Measuring Systems® a participé à la 20e édition du salon Laborama à Bruxelles Expo.
Le rapport consacré à la surveillance de la contamination dans les systèmes de distribution de produits chimiques a beaucoup intéressé les participants au symposium UCPSS 2018
« Stratégies avancées d’analyse des données pour comprendre la contamination particulaire dans les systèmes de distribution de produits chimiques »
Learn where to place sample points for certification
As environmental system designers, we are often asked where to place sample points for particle monitoring, whether it be performed in a pharmaceutical cleanroom or clean device (RABS, isolator, etc.).
A Comparison of Particle Counting Solutions for UPW
Through continuous process and equipment advancements, semiconductor manufacturers are approaching 14 nm feature sizes and heading even smaller, while hard-disk drive fly heights are now less than 10 nm. This ever-reducing device feature size requires comparable cleanliness-level improvements in ultrapure water (UPW). UPW purity is especially important with its high use in direct contact with wafers as a final cleaning and rinsing agent in many production steps. Leveraging recent advances in laser optics and detector technology, UPW particle concentration ≥20 nm (≥9 nm for metallic particles) can be effectively monitored.
Are your particle counters ISO 14644-1 compliant?
Are your particle counters ISO 14644-1 compliant and able to be calibrated to all required tests according to ISO 21504-4?
New paper: ISO 14644 Revisions Summary
The recent revision of ISO 14644-1 and-2 has introduced several changes for cleanroom classification and monitoring guidelines. This paper highlights the major changes in the new ISO 14644-1 compared to the previous version, as well as the possible impact on the Pharmaceutical EU GMP Annex 1 and FDA Aseptic Processing Guideline.
