Method Changes

As part of the NLS commitment to quality, we constantly review the performance data both from our own internal quality control measures and those from the external quality assurance schemes that we participate in. The analysis of this data allows us to ensure as up to date reflection of our analytical capabilities as possible.

As a result, we will periodically change reporting limits and accreditation status in line with the performance of each method. This ensures the robustness of the results that we send to you. All results, including those that do not carry accreditation, are generated using methods that have been validated to the standard required by our accreditation to ISO 17025.

Our most recent method changes are detailed in a file for download here: Test changes July 2011. Existing NLS customers affected by these changes will receive an email from us that details the changes to their requested analysis.
