The determination of metaldehyde in waters using chromatography with mass spectrometric detection (2009)
Methods for the Examination of Waters and Associated Materials
This booklet contains six methods for the determination of metaldehyde in waters. Each method has been validated in only one laboratory and consequently details are included for information purposes only as examples of the type of procedures that are available to analysts. Information on routine multi-laboratory use of these methods would be welcomed to assess their full capabilities.
Whilst this booklet may report details of the materials actually used, this does not constitute an endorsement of these products but serves only as illustrative examples. Equivalent products are available and it should be understood that the performance characteristics of the methods might differ when other materials are used. It is left to users to evaluate methods in their own laboratories.
