Portable, On-line and Laboratory Water Analysis Systems

Importance of the Topic

Water quality directly impacts public health, ecosystem stability and industrial processes. Ensuring access to clean drinking water and mitigating environmental pollution are critical global challenges. Advanced analytical methods and instrumentation are essential for accurate monitoring of physical, chemical and biological contaminants across diverse water matrices.

Objectives and Overview of the Portfolio

This document presents a comprehensive suite of portable, on-line and laboratory-based solutions for water quality analysis. It aims to equip scientists, environmental managers and industrial operators with integrated workflows—from sampling and preservation to data management—covering routine parameters, emerging organic and inorganic contaminants, microbiological hazards, radiotoxic species and toxicity testing.

Methodology and Instrumentation

Key methodological areas include:

• Sample Collection, Transfer and Storage: High-performance refrigerators, pipettes and pure-water systems.
• Microbiological Testing: Culture methods, enzyme assays, magnetic-bead purification and rapid PCR detection.
• Electrochemistry and Colorimetry: pH, ion-selective electrodes, conductivity, DO and colorimetric COD/TP/TN measurements.
• Optical Spectroscopy: UV-Vis spectrophotometry for nutrient and turbidity analyses; FT-IR for oil-in-water determination.
• On-Line Monitoring: Electrochemical and colorimetric process analyzers, digital sensor networks and ion chromatography systems for continuous in-process control.
• Sample Pretreatment: Automated solid-phase extraction, headspace and SPME techniques for volatile and semi-volatile organics.
• Chromatography and Mass Spectrometry: GC, GC-MS, triple-quadrupole and high-resolution MS for VOCs, PAHs, pesticides, dioxins and emerging contaminants; LC-MS for PPCPs and microcystins.
• Elemental Analysis: AAS, ICP-OES, ICP-MS and speciation interfaces for toxic metals, anions/cations and disinfection byproducts.
• Radiation and Toxicity Testing: Alpha/beta/gamma detectors for radiochemical monitoring and bioassays including luminescent bacteria and high-content imaging.
