Trace Metals
A suitable supply of leachate was obtained and filtered through a 0.45 µm membrane
filter. This material was stabilised with concentrated nitric acid to provide a pH of <2.
This material is intended for use in development, validation or quality control of
analytical methods for the determination of elements in landfill leachates.
