FISHYMAG FICTIONAL LABORATORY REQUEST EXAMPLE Please confirm whether you can report elemental copper in µg Cu/L for the described marine aquarium water sample from display point D1 at the recorded collection time. The question concerns the sampled water only. Please specify the applicable operational fraction, method and matrix validation, and the quantitative reporting capability. Numerical reporting at 2 µg Cu/L is the fictional procurement requirement, not a livestock-safety threshold. Please supply your sample requirements and quality-control/reporting notes before a service is selected. This request does not ask for a verdict about deposits, free-ion activity, all copper species or livestock clearance.
