Water quality - Determination of selected non-polar substances - Method using gas chromatography with mass spectrometric detection (GC-MS)

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]

Water quality - Determination of selected non-polar substances - Method using gas chromatography with mass spectrometric detection (GC-MS)

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]

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
