The Metalyser
®
has been designed for low
level ppb analysis in natural water. The
instrument will measure high limits by
a) choosing a shorter deposition time (i.e.
change default from 60 to 30 seconds when
prompted in the Set Deposition time menu
during the course of the run)
b) diluting the sample by a known amount
and multiplying the result back to the original
solution
