This Technical Specification specifies a method for the determination by gas chromatography with mass spectrometric detection (GC-MS) of polycyclic hydrocarbons and pesticide residues in drinking water and ground water at mass concentrations above 0,005 μg/l and surface water and waste water at mass concentrations above 0,01 μg/l (for each single compound). This method can apply to non-polar substances other than polycylic aromatic hydrocarbons (PAH) and pesticide residues. However, it is necessary to verify the applicability of this method for these compounds. NOTE 1 A potentially suitable method for this verification is specified in ISO/TS 13530.[3] This Technical Specification can be used for samples containing up to 150 mg/l of suspended matter. NOTE 2 Determination of PAH using GC-MS lies within the scope of ISO 28540.[9]

Abstract

Overview

ISO/TS 28581:2012 - "Water quality - Determination of selected non-polar substances - Method using gas chromatography with mass spectrometric detection (GC‑MS)" - specifies a validated analytical procedure for measuring selected non‑polar organic compounds in water by gas chromatography–mass spectrometry (GC‑MS). The method targets polycyclic aromatic hydrocarbons (PAH), polychlorinated biphenyls (PCB), organochlorine pesticides and other non‑polar substances in drinking water, groundwater, surface water and wastewater at low trace levels (typical limits: 0.005 μg/L for drinking/groundwater; 0.01 μg/L for surface/wastewater). The procedure covers sample extraction, concentration, clean‑up, separation and mass‑spectrometric identification/quantification.

Key Topics and Requirements

Scope and analytes: Lists determinable non‑polar substances (PAH, PCB, organochlorine pesticides) and notes applicability to similar non‑polar compounds after verification.
Sampling limits: Usable for samples with up to 150 mg/L suspended matter; sampling/preservation references to ISO 5667 series.
Sample preparation: Liquid–liquid extraction (hexane or equivalent solvents) with an internal standard mixture added before extraction; concentration by evaporation and solvent exchange where needed.
Clean‑up: Optional column chromatography for surface or wastewater extracts to remove interferences.
Chromatography: Separation on fused‑silica capillary columns with non‑polar or slightly polar polysiloxane stationary phases suitable for isomer separation.
Mass spectrometry: Electron‑impact (EI) ionization and use of selected ion monitoring (SIM) for identification/quantification; injection standards added prior to GC injection.
Calibration & QC: Calibration using internal or isotopically labelled internal standards; blank measurements, recovery checks, and performance criteria are specified (see ISO 8466‑1 for calibration evaluation).
Interferences: Guidance on sampling, extraction, GC and MS interferences and required verification for novel analytes.

Applications - Who Uses This Standard

Environmental and water‑testing laboratories performing routine monitoring of drinking water, groundwater, surface water and wastewater.
Regulatory agencies and drinking water utilities enforcing contaminant limits (e.g., benzo[a]pyrene and other PAH).
Contract laboratories providing compliance testing for pesticides, PCBs and PAH.
Research groups developing or validating trace‑level methods for non‑polar organic contaminants.
