ManufacturerSignificance of the Topic
Ensuring safe and compliant water quality is critical for public health, environmental protection and industrial processes. Comprehensive analytical services are essential to detect and quantify trace contaminants, metals, organics and biological parameters across diverse water matrices. ALS Global’s water product catalogue presents a wide range of accredited methods to support regulatory compliance, risk assessment and process optimization.
Objectives and Catalogue Overview
The catalogue aims to provide a clear overview of analytical packages for:
- Drinking water monitoring (microbiology, metals, anions, organics, radiology)
- Environmental waters (seawater, brackish and freshwater metals, anions, nitrogen species)
- Wastewater and industrial streams (indicator parameters, organic pollutant fractions, VOCs, pesticides)
- Advanced services (ecotoxicity, radiometric analyses, passive sampling, PFAS screening)
Methodologies and Instrumentation
ALS deploys state-of-the-art techniques and accredited laboratories under ISO 17025, including:
- Elemental analysis: ICP-OES, ICP-MS, AFS for ultra-trace metals
- Anion and cyanide determination: Ion chromatography (IC)
- Volatile and semi-volatile organics: GC-MS, GC-FID, GC-ECD, headspace techniques
- Non-volatile and polar organics: LC-MS/MS, HPLC-DAD
- Bulk parameters: TOC, DOC, AOX by FTIR and combustion methods
- Radiochemistry: Gamma spectrometry, liquid scintillation, alpha/beta counting
- Ecotoxicity testing: Acute and chronic bioassays with Daphnia, algae, fish, luminescent bacteria
- Passive sampling: PS-Organic, PS-Polar, PS-Metal and PS-VOC devices for time-integrated monitoring
Main Offerings and Discussion
The catalogue details over 200 parameters with indicative limits of quantification (LOQs), sample volumes and preferred sample containers. Key sections include:
- Drinking water suite: from low-level metals and anions to disinfection byproducts and polycyclic aromatic hydrocarbons (PAHs)
- Environmental metals: tailored LOQs for seawater, brackish and freshwater matrices
- Organic pollutants: comprehensive VOC packages (EPA-8260), fuel additives and petroleum hydrocarbon fractions (C5–C40)
- Pesticides: multi-residue screening, acidic herbicides, organochlorine and organophosphorus compounds
- Emerging contaminants: PFAS profiling, total oxidisable precursor (TOP) assay
Benefits and Practical Use
The ALS Water Catalogue offers:
- Customizable packages aligned with regulatory standards (EU Water Framework Directive, WHO, EPA)
- Rapid turnaround options (ALS Quick) and online data access
- Global network of ISO-accredited laboratories ensuring consistent quality
- Expert support for method selection, sampling logistics and data interpretation
Future Trends and Applications
Emerging priorities include:
- Expanded PFAS screening beyond PFOA and PFOS using TOP Assay and high-resolution MS
- Integration of passive samplers for long-term, site-specific pollutant profiling
- Advances in miniaturized and field-deployable instruments for real-time monitoring
- Data analytics and digital platforms to support predictive water quality management
Conclusion
ALS Global’s water analytical services catalogue delivers a robust framework for comprehensive water quality assessment. By combining advanced methodologies, global accreditation and customer-centric solutions, ALS supports stakeholders in safeguarding water resources, meeting compliance requirements and driving sustainable operations.
