This document specifies a method for the determination of alkylmercury compounds in filtered water samples by gas chromatography-mass spectrometry after phenylation and solvent extraction. This method is applicable to determination of individual methylmercury (MeHg) and ethylmercury (EtHg) compounds in surface water and waste water. The method can be applied to samples containing 0,2 μg/l to 10 μg/l of each compound as mercury mass. Depending on the matrix, the method may also be applicable to h...view more

This document specifies operationally defined methods for the determination of total cyanide in various types of water such as drinking water, ground water, surface water, wastewaters, metallurgical processing tailings reclaim solution, heap leach barren solution, mill slurry tailings filtrate and leaching solutions, with cyanide concentrations from 5 µg/l to 2 000 mg/l expressed as cyanide ions in the undiluted sample. The range of application can be extended by reducing the sensitivity (Figure...view more

This document specifies a multi‑parameter method for the determination of total organic carbon (TOC), total nitrogen (TNb) and total phosphorus (TP) in drinking water, raw water, ground water, surface water, sea water, saline water, process water, domestic and industrial wastewater, after a chemical oxidation process.

This procedure specifies a method for the determination of 228Ra activity in drinking waters by radium
extraction, purification and liquid scintillation counting.

This standard specifies a method for the measurement of 99Tc in all types of waters by inductively coupled plasma mass spectrometry (ICP-MS).
The method described in this standard, using currently available ICP-MS, has a detection limit of approximately 0,2 to 0,5 ng•L-1 (0,1 to 0,3 Bq•kg-1), which is much lower than the WHO criteria for safe consumption of drinking water (100 Bq•L-1). The method presented in this standard is not intended for the determination of ultra-trace amount of 99Tc.

This standard specifies a method for the measurement of 99Tc in all types of waters by liquid
scintillation counting (LSC).
The detection limit depends on the sample volume and the instrument used. The method described in
this standard, using currently available LSC counters, has a detection limit of approximately 5 to 20
Bq•kg-1, which is lower than the WHO criteria for safe consumption of drinking water (100 Bq•L-1).
These values can be achieved with a counting time of 30 minutes for a sa...view more

This International Standard gives criteria for mass spectrometric identification of target compounds in water. This document is a guideline for the identification of molecules <1 200 Da. For identification of larger molecules additional investigations are recommended.
This standard shall be used in conjunction with standards developed for the determination of the specific compounds. If the standards for analysing specific compounds give criteria for identification, those criteria shall be follow...view more

This  document specifies the critical issues to address when developing in a laboratory a method for the simultaneous quantitative analysis of numerous organic compounds in water.

This part of ISO 5815 specifies the determination of the biochemical oxygen demand of waters by dilution and seeding with suppression of nitrification after 5 d incubation time.
This part of ISO 5815 is applicable to all waters having biochemical oxygen demands usually between 3 mg/l and 6 000 mg/l. It applies particularly to waste waters. For biochemical oxygen demands greater than 6 000 mg/l of oxygen, the method is still applicable, but the errors caused by the necessary dilutions can influen...view more

This document specifies a method for the determination of selected perfluoroalkyl and polyfluoroalkyl substances (PFAS) in non-filtrated waters, for example drinking water, natural water (fresh water and sea water) and waste water containing less than 2 g/l solid particulate material (SPM) using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The compounds monitored by this method are typically the linear isomers. The group of compounds determined by this method are representative of ...view more

This document specifies methods used to determine the concentration of plutonium and neptunium
isotopes in water by inductively coupled plasma mass spectrometry (ICP-MS) (239Pu, 240Pu, 241Pu
and 237Np). The concentrations obtained can be converted into activity concentrations of the different
isotopes[9].
Due to its relatively short half-life and 238U isobaric interference, 238Pu can hardly be measured by
this method. To quantify this isotope, other techniques can be used (ICP-MS with colli...view more

The compounds monitored by this method are typically the linear isomers. The group of compounds determined by this method are representative of ...view more

This European Standard specifies determination of the biochemical oxygen demand of waters of undiluted samples. This standard is applicable to all waters having biochemical oxygen demands greater than or equal to the limit of determination 0,5 mg/l of oxygen and not exceeding 6 mg/l of oxygen.

This document specifies the criteria for mass spectrometric identification of target compounds in water samples and is applicable to environmental samples in general. This document is intended to be used in conjunction with standards developed for the determination of specific compounds. If a standard method for analysing specific compounds includes criteria for identification, those criteria are followed.

This document specifies the criteria for developing an in-house mass spectrometry-based method for quantitative analysis of multiple subgroups of organic substances in the scope of physical-chemical analysis of water.
This document supplements ISO/TS 13530 which provides guidance on the initial characterization of the measurement performances, by providing details to select the test matrix and internal standards and criteria for analyte and internal standard recoveries.

This document specifies the determination of the biochemical oxygen demand of waters by dilution and seeding with suppression of nitrification after 5 d or 7 d incubation time.
It is applicable to all waters having biochemical oxygen demands usually between 1 mg/l and 6 000 mg/l. It applies particularly to waste waters but also suits for the analysis of natural waters. For biochemical oxygen demands greater than 6 000 mg/l of oxygen, the method is still applicable, but special care is needed ta...view more

This part of ISO 17378 specifies a method for the determination of arsenic and antimony. The method
is applicable to drinking water, surface water, ground water, and rain water. The approximate linear
application range of this part of ISO 17378 for both elements is from 0,5 μg/l to 20 μg/l. Samples
containing higher concentrations than the application range can be analysed following appropriate
dilution.
Generally sea water is outside the scope of this part of ISO 17378. Sea water samples c...view more
