The Nutrient Chemistry Labs are staffed and equipped to analyse and measure: Phosphorus (total, dissolved, soluble reactive); Nitrogen (total dissolved, NO3, NO2, NH4); Dissolved silicon; Dissolved organic carbon (DOC); Major anions (F, Cl, Br, SO4); Chlorophyll-a ; Suspended solids; pH; Gran Alkalinity; Conductivity. All sample batches are run alongside external quality control standards (Aquacheck system).
The Nutrient Chemistry Labs provide an ongoing service for UKCEH research. Equipment typically has a 5-10 years lifespan, and is maintained and replaced on a constant cycle, either at end-of-life or as newer technologies become available.
The Nutrient Chemistry Labs are unique in using flow cytometry to analyse water samples for algal composition. River and effluent samples are filtered in the field, and all unstable nutrient parameters are analysed within a day of arriving in the laboratory to ensure the highest quality data.

The Nutrient Chemistry Laboratories are used primarily to support the Thames Initiative and local nutrient research projects, plus BGS staff based at UKCEH Wallingford. They may be available to other research organisations, usually in collaboration with UKCEH: initial inquiries via UKCEH Wallingford.
The Nutrient Chemistry Labs are based at UKCEH Wallingford.
UKRI-NERC National Capability funding: UK-SCaPE programme (LTSS) and ASSIST programme (LTSM). Plus research project grants from Thames Water, EA, Canal and Rivers Trust, Rivers Trusts etc.
