We are developing our methods for metal analysis in water and from April 1st  2023 we will offer an extended scope of accredited metal analyses, a request from our clients. The development will also contribute to a reduced environmental impact.

Extended element scope of accredited analyses 
By introducing the new methods, we will offer accredited analyses of 68 elements, instead of around 30 that we offer today. The accredited elements include rare earth elements (REEs) and other elements with increasing environmental relevance, such as silver (Ag), uranium (U) and thallium (Tl). 

Instead of using three instrument techniques to analyse metals in water, we will now be able to perform the analyses using only two techniques (ICP-SFMS and AFS). All metals will be analysed by high-resolution ICP-MS (ICP-SFMS), with the exception of mercury (Hg) at low reporting limits, which will still be analysed by atomic fluorescence (AFS). 

Reduced environmental impact 
In addition to the extended scope of accredited elements, the development results in a reduction in our environmental impact. As the number of instrumental analyses significantly reduce, the amount of chemicals, containers, electricity and argon will decrease. The sample volume required for the analysis is also reduced, resulting in a decrease in transport emissions. This is well in line with our priority focus on climate neutrality. 

Special offer with lower reporting limits 
Our routine analysis packages for metals in water (e.g. V-2, V-3a, V-3b etc) will not change but the number of additional packages will decrease. This will hopefully make it easier for you as a client to order additional analyses. For most elements, reporting limits will be unaffected or decreased. However, for a few elements, the reporting limit (LOR) will be slightly increased for the routine water analyses. This applies to chromium (Cr), zinc (Zn), vanadium (V) and barium (Ba). 

We will also offer packages for high-quality water analyses with lower reporting limits, with most reporting limits as low as ng/l. 

Standard and scope of analysis 
Like the current validated methods, the new water methods are based on SS-EN-ISO 17294-2:2005. The accreditation includes all relevant water matrices such as freshwater, seawater, wastewater, drinking water etc, with or without prior digestion, as well as the following 68 elements, marked in blue in the periodic table below:
