Tender: Supply of Two Ion Chromatography Systems for Anion and Bromate Analysis – Institute of Naval Medicine (EIH Laboratory)

About

The Environmental and Industrial Hazards (EIH) Laboratory at the Institute of Naval Medicine is seeking a supplier for two ion chromatography systems to replace the current ion chromatograph which has reached the end of its useful life and to provide additional capability according to new requirements. The systems will primarily be used for analysis of anions in raw, potable and bottled water in accordance with service doctrine and UK drinking water legislation, and will also be used for environmental matrices including groundwater, surface water and wastewater. One ion chromatograph must be capable of analysing nine anions (fluoride, chlorite, chloride, nitrite, chlorate, bromide, nitrate, sulphate and phosphate) using conductivity detection. The other must be capable of analysing bromate in samples with elevated levels of chloride using post-column derivatisation with potassium iodide and absorbance detection of triiodide by a UV-Vis detector. Both systems must meet the trueness, precision and limit of detection requirements detailed in The Water Supply (Water Quality) Regulations 2018.
