Application Notes: General

Ensuring the safety of drinking water is a critical public health priority shaped by increasingly stringent global regulations. This eBook provides a focused guide to meeting the requirements of EU Directive 2020/2184, outlining advanced analytical strategies for detecting a wide range of contaminants, from persistent organic pollutants and disinfection by-products to trace-level metals. The directive sets ambitious monitoring and quality standards designed to protect public health across increasingly complex water systems.

Submicron optical photothermal infrared (O-PTIR) spectroscopy is transforming particulate and aggregate analysis in biopharmaceuticals by delivering true IR and Raman chemical specificity below the diffraction limit. This paper explores how O-PTIR overcomes long-standing challenges associated with FTIR, Raman, and fluorescence techniques, enabling high-resolution, artefact-free characterization of complex protein and polymeric particulates. Real-world case studies demonstrate how simultaneous IR+Raman measurements reveal chemical heterogeneity and insights critical for reducing immunogenicity in advanced therapeutics.
