Hi guys

I am currently in the first year of my PhD and trying to set up an HPLC method for the analysis of phosphonate scale inhibitors. The method was previously developed a few years ago by a member of staff who is no longer here and although the method works ok I am a bit confused as to why the column used was chosen.

The method uses a Dionex AS11-HC column which is designed for the analysis of anions, however I am analysing scale inhibitors. Does this seem odd to anyone? Why would such a column be chosen?

Any advice would be appreciated :)

That's not that strange as phosphonates are organic acids based on phosphonic acid See http://en.wikipedia.org/wiki/Phosphonate.

It seems perfectly reasonable to me. That column is good for measuring phosphonates. You are looking for things
that inhibit phosponates so look for the least amount of phosphonates produced.
