BS EN ISO 12010:2019

What is ISO 12010‒ Short-chain polychlorinated alkanes in water about?  

ISO 12010 is an international standard that deals with various aspects of maintaining water quality. 

ISO 12010 specifies a method for the quantitative determination of the sum of short-chain polychlorinated n-alkanes also known as short-chain polychlorinated paraffin (SCCPs) in the carbon bond range n-C10 to n-C13 inclusive, in mixtures with chlorine mass fractions (contents) between 50 % and 67 %, including approximately 6000 of approximately 8000 congeners. 

ISO 12010 applies to the determination of the sum of SCCPs in unfiltered surface water, groundwater, drinking water, and wastewater using gas chromatography-mass spectrometry with electron capture negative ionization (GC-ECNI-MS). 

Note 1: The user should be aware that particular problems might require the specifications of additional marginal conditions. 

Who is ISO 12010‒ Short-chain polychlorinated alkanes in water for? 

ISO 12010 on short-chain polychlorinated alkanes in water is used by: 

• Wastewater collecting systems 
• Wastewater treatment plants 
• Plants treating industrial wastewater 
• Water supply treatment plants 

Why should you use ISO 12010‒ Short-chain polychlorinated alkanes in water? 

Water quality gives you information about the condition of the water, consisting of the chemical properties, physical and biological characteristics with respect to its usage for a particular purpose such as drinking, swimming, or industrial use. 

ISO 12010 gives you the procedure for the determination of the sum of short-chain polychlorinated alkanes in the carbon bond range n-C10 to n-C13 inclusive, in technical and environmental transposed mixtures with chlorine mass fractions and independent of the C-number distribution pattern of the congeners. These analyzed sums of SCCPs give you a variety of SCCPs with their differing chlorine content and C-number distribution patterns as found in technical mixtures as well as compositions in the environment. 

ISO 12010 also provides you with details about undertaking a gas chromatography (GC) method using a short capillary column within a short retention time range. It further tells you about carrying out the detection of selected mass fragments, with the help of mass spectrometry (MS) in selected ion-monitoring mode using electron capture negative ionization mode (ECNI).  

It also talks about the importance of the mass fragments and the compositions of the calibration solutions, as they are essential for the analysis of the sum of SCCPs. 

What’s changed since the last update? 

BS EN ISO 12010:2019 supersedes BS EN ISO 12010:2014, which is withdrawn. The main changes compared to the previous edition are: 

• The m/z values (mass/charge ratios) for quantification and identification 
• The calibration mixtures 
• The cleanup procedure by gel chromatography 
• Reduced interferences
