Following a tender exercise published through the Official Journal of the European Union (OJEU), the British Geological Survey (BGS) was contracted by GSI to undertake several of the work packages (Lots) for provision of services for sample preparation and geochemical analysis. This report summarises work carried out under:
- Lot 5 –Multi-element analyses of filtered stream water samples
The requirements of Lot 5 included analysis by Inductively-Coupled Plasma Mass Spectrometry (ICP-MS) or equivalent alternative, non-purgeable organic carbon (NPOC); major anions by ion chromatography (IC).
The analytical work programme was tendered during January–February 2012, with contractual negotiations completed during March to enable work to begin in early April 2012. Due to the time constraints of the overall Tellus Border project, there was significant pressure to ensure that the analytical programme was completed as quickly as practicable, to allow for subsequent data interpretation activities. Analytical throughput and turnaround time was therefore an explicit consideration during tender evaluation and a major priority throughout the execution.
