Description
The Environmental and Industrial Hazards (EIH) Laboratory at the Institute of Naval Medicine requires 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 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.

Procedure
Procedure type
Open procedure
Justification for not publishing a preliminary market engagement notice
In this instance, a preliminary market engagement notice was not published because the need for this requirement was only identified and developed within the last two months. Therefore, issuing an advance notice so close to the release of this Tender notice would not have been beneficial. Additionally, the contracting authority has sufficient knowledge of the market and potential suppliers based on previous similar requirements and market research.
