Total Phosphorus results get an extra significant figure
AST has undertaken a review of data and is now reporting Total Phosphorus with an extra significant figure.
This will be particularly valuable to clients who have regulatory limits close to our method reporting limits.
Measurement Uncertainty (MU) can also have a significant influnence when interpreting results at or close to reporting or regulatory limits.
We have also updated our Nutrients information page to include MU ranges for different analytes.
Please contact us if you have any questions or concerns about our method reporting limits or associated measurement uncertainty. One of our chemists will be able to talk it through with you.
