It is possible to work on top of the interferences using a ultra clean
H2SO4 blank such as SeaStar sulfuric. With the exception of Zn, we are
able to calibrate at 100 and 500 ppt. Zn can be analyzed by some other
method such as GFAAS.

Please respond to
Thanks for everyone who respond to me on sulfuric acid analysis,but
according to your experience,does an analytical technic permit a report
value in Zn,V,Ge,Ti at ppb level or sub-ppb level excluding DRC and if the
MSA technic doesn`t correct polyatomic interference,how can I detect them
or correct them.And at the end,does an Elan 6100 is more problematic for
this type of analysis than other like HP 7500 whith a lower oxide level.
