The systems will primarily be used for analysis of anions in raw, potable and bottled water samples in accordance with the requirements of service doctrine1, 2, 3 and UK drinking water legislation4, 5, but other matrices will include environmental samples such as groundwater, surface water and wastewater. One Ion Chromatograph must be capable of analysing 9 anions (fluoride, chlorite, chloride, nitrite, chlorate, bromide, nitrate, sulphate and phosphate) using conductivity detection. The other Ion Chromatograph must be capable of analysing bromate in samples with elevated levels of chloride with post column derivatisation and absorbance detection. Specifically, post column addition of potassium iodide followed by detection of triiodide using a uv-vis detector. The systems must meet the requirements for trueness, precision and limit of detection detailed in The Water Supply (Water Quality) Regulations 2018.
