Hi Mr. Chandrashekar,

I was able to find a HPLC method for you, using Reverse Phase Ion Pairing... here is the link:

http://pubs.acs.org/doi/abs/10.1021/ac00236a053

Looks like any good C8 column will work well for you.

Paul

B. Chandrashekhar

Thats good. I will look to standardize this method. Thanks Mr. Karch.

Hello Mr. Chandrashekar,

I want to analyze the complex Fe-NTA as well. The concentrations will be up to 0.1M in water. What column, detector and mobile phase did you use?

Thank you so much,

Fernando
