Does anyone know when USP will be making this application available?

If you're referring to the lower database on the following web page, there is an email link on their www page, and you could ask them about the specific part you're interested in.

There is an earlier thread in this forum that contains pointers to the published literature the database is based on. A seach on US Pharmacopeia Column Comparision Database should find it.

Indium,

Are you talking about separate classification/database for orthogonal columns? Mixed mode columns are orthogonal:

but at this point I am not sure that USP has a separate classification for mixed mode. We are in discussions with USP about categorizing these columns

Are the USP/PQRI databases in the beta stage? Have they been formally unvailed?

No idea, it's not on their "what's new" list. I suppose it depends when George Bush was/is available to perform the official unveiling. As noted, there's an email link on the page, why not ask them?.

Totally unrelated rant, but it's disappointing to see that the USP is now going to publish the Food Chemicals Codex, the price will skyrocket, and the supplements and editions will become as extortionate as those of the USP.

They showed a poster at the HPLC 2006 meeting in San Francisco in June. It was fairly uninformative, essentially saying "coming soon". It had a redeeming feature in that it clearly displayed the URL, in effect making public disclosure. As far as I know, there is no link to it from anywhere else on their web site.
