Water quality - Determination of dissolved anions by liquid chromatography of ions - Part 1 : determination of bromide, chloride, fluoride, nitrate, nitrite, phosphate and sulfate
ISO 10304-1:2007 specifies a method for the determination of dissolved bromide, chloride, fluoride, nitrate, nitrite, orthophosphate and sulfate in water, e.g. drinking water, ground water, surface water, waste water, leachates and marine water by liquid chromatography of ions. The lower limit of application is greater than or equal to 0,05 mg/l for bromide and for nitrite, and greater than or equal to 0,1 mg/l for chloride, fluoride, nitrate, orthophosphate, and sulfate. The lower limit of application depends on the matrix and the interferences encountered.The working range may be expanded to lower concentrations (e.g. greater than or equal to 0,01 mg/l) if an appropriate pre‑treatment of the sample (e.g. conditions for trace analyses, pre‑concentration technique) is applied, and/or if an UV detector (for bromide, nitrate and nitrite) is used.

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!

- With a single click, add a new language, the Requirements or Redline+ service and add one or more additional users.
- Whether you are in the process of acquiring a standard or it is already available in your personal space, the UPSELL service is available at every stage to help you understand it and implement it within your organization.
