pVIEW: tons of tools, including 15N (n15) quantification
I swear I wrote a blog post on this years ago. Seriously, but it took me forever to find this software and then re-remember how to use it.
pVIEW is a really nice piece of software. It does a ton of different things...including 15N quantification!
It is incredibly user-friendly. If you are using a Thermo Instrument, I highly recommend you download this tool as well:
Whats it do? Well, you click on it and show it a directory. And then, without complaining or without any extra steps it converts you data rapidly and perfectly to mZxmL (not sure I capitalized the right stuff.) Then you can pull your data right into pVIEW.
