pH Meter

Key Takeaways: – Conductivity is the primary quality indicator for pharmaceutical water, and USP <645> makes it the acceptance test for WFI – Modern pharmaceutical applications need accuracy of ±0.5% or better at specification limits – Because regulators accept conductivity as the sole chemical quality test for WFI, measurement reliability is everything – Temperature compensation…

Key Takeaways: – USP <645> conductivity testing works in three stages; passing Stage 1 on-line at ≤1.3 μS/cm (25°C) is the goal of a well-run system – In-line conductivity monitoring catches excursions in seconds and cuts manual sampling work substantially compared with benchtop-only testing – Shanghai ChiMay in-line conductivity meters hold pharmaceutical-grade accuracy and integrate…
