3.5. INTERFERENCE EFFECTS
The Metalyser
®
has been designed to test very low levels of metals in water
and as such is very sensitive. Due to the interaction of other metals and
organics in the water source, interferences can occur as with any system of
this type.
The Metalyser
®
is designed to function in water sources that might be suitable for
drinking. The buffers chosen mean that in many instances interferences are unlikely to
occur.

Lower limits achievable using the Handset at 60 seconds deposition.
Increased accuracy can be achieved by setting the deposition time to 120 seconds
Variability at 20ppb ± 5% with Metaware software, ± 7.5% with handheld
Accuracy dependent on element measured, sample matrix and type
