United States Pharmacopoeia (USP) general chapter <1058> on Analytical Instrument Qualification (AIQ) now has a new title from a draft update for public comment: Analytical Instrument and System Qualification (AISQ). A new three-phase integrated lifecycle phase approach to qualification and validation is described. But will laboratories and suppliers implement it?

A study from Chinese researchers demonstrates how combining satellite imagery, land use data, and machine learning can improve pollution monitoring in fast-changing urban rivers. The study focuses on non-optically active pollutants in the Weihe River Basin and showcases promising results for remote, data-driven water quality assessments.

Researchers at Zhejiang University have developed an advanced optical modeling approach using spectroscopic ellipsometry, significantly enhancing the non-destructive analysis of amorphous silicon oxide thin films.

New research highlights how remote satellite sensing technologies are changing the way scientists monitor inland water quality, offering powerful tools for tracking pollutants, analyzing ecological health, and supporting environmental policies across the globe.
