Trace metals - heavy metals,  who cares?

Our technology, in short

 

Sensitivity, detection limit:

three times the system noise gives detection limit of 5ng/l  (or 5*10-12)  on Zn, Cd, Pb and Cu

naturally occurring in clean Atlantic seawater has:

2ng/l of Cd,             30ng/l of Pb                 200ng/l of Cu                    1000ng/l of Zn

 

 

 

Repeatability:

example test with 80 measurements put on top of each other to show stability:

 

Long term measurement:

6 weeks automated continuously almost 900 analysis and almost one result every hour with standard addition two times to each sample:
