Thanks Daniel and Johan for the feedbacks, they are much
we are conducting investigation in the Ag transference
(bulk and nanoparticled) in a simulated freshwater food
chain and we are using Pseudokirchneriella subcapitata
(formerly known as Selenastrum capricornutum) as producer.
That is why I was so surprised by the relative absence of
CRMs for Ag, especially since the nanoparticles are kind
of a hot topic at the moment.
