Hello dear sirs!

Now I have the system DIONEX 2100 IC (ASRS 300-suppressor, AG19+AS19-trap column+column, conductivity cell)

I started this system successfully and now can don analysis of UPW in ppb-range.
I am not so expirienced in the ioni chromatography. From me demand to carry out analysis H2O2 of 30 %, HCl 35 %, NH3 water solution 28 % (all chemicals ULSI-grade). If to lead sample preparation only diluting I also reduce concentration of impurity. Help me please. How to lead sample preparation for the analysis of mentioned above chemicals?

Thankful in advance for the answer.

There is no single simple answer to that question. It depends on what impurities and at what levels you need to ionize. If it were my problem, I would first contact Thermo/Dionex. They have quite a library of applications notes and may well be able to give you "cookbook" recipes for several of those.

Hi Off Day,

I take it you want to analyze anions in each of these independent sample matrices? If that is the case we may have some solutions for you. Probably better we chat off line and discuss how best to proceed with these applications. Can we contact you via e-mail?
