I am having issues in detection of nitrite in environmental samples because of carbonate presence (in the samples). I use Dionex ICS 2000 system with AS18 column, KOH eluent: 30 mM, 1 ml/min.
Unfortunately, changing the eluent concentration from 30mM to lower level (recommended 23mM) could not fix the problem. Gradient elution messed up the detection of the other analytes of our interest. Any other ideas?
I am thinking of ordering a CRD, but do not know anybody who have any experience. I do not know the lifetime of the device, does it require any regeneration during its use. Any help?
Thanks,
Jozsef
