As part of the NLS commitment to quality, we constantly review the performance data both from our own internal quality control measures and those from the external quality assurance schemes that we participate in. The analysis of this data allows us to ensure as up to date reflection of our analytical capabilities as possible.

As a result, we will periodically change reporting limits and accreditation status in line with the performance of each method. This ensures the robustness of the results that we send to you.

Latest technology for analysing metals in seawater

The National Laboratory Service have made significant improvements to how some metallic elements are analysed in saline and estuarine waters, which is a challenging task due to the salt matrix and the very low detection limits required.

Previously samples were analysed using a matrix elimination and concentration method that was both time consuming and used expensive reagents, and the analysis took place on two separate instruments. This has now been replaced using the latest technology Inductively Coupled Plasma Mass Spectrometry (ICPMS) incorporating on-line gas dilution and Collision Cell Technology. This investment will result in significant improvements, and has the potential for further developments in the future.

This ground breaking work is available as an application note on the instrument manufacturer’s website and is due to be presented at the 2018 Agilent Enviro and Food MS meeting at Twickenham.
