Antioxidants in polyols

[ilycip2015]

Hi,
Could tell me somebody an analysis method for antioxidants and for antioxidants in polyols on HPLC?

[Vlad Orlovsky]

What are you trying to analyze? Do you have list of antioxidants?

[ilycip2015]

Hi,
I try to analyze antioxidants with free amines like: PLX 991, AOX 215, Irganox1076 ...

[Vlad Orlovsky]

Most of the people have no idea what these numbers mean and need to Google it, how hard it ti to paste structures or describe them or reference then to a list. You need to help us to help you.

Something like these:

Hi ilycip2015,

I agree with Vlad--of the three you mention, Irganox 1076 is a hindered phenol as opposed to an amine:

Are you looking at antioxidants in food, cosmetics, plastics...what are your intended goal(s)?

An easy thing to try is to go to HPLC vendor websites, such as Agilent, Waters, Supelco, Restek...and others as they may have applications to view there. Or as Vlad mentions...Google Scholar is also a great source of information.

Best Wishes!
