Yes

This method provides quantitation of total PACs by a specific LC method

I know that this is the calibration approach everyone uses, but I worry about the linear response of the higher order polymers compared with the monomer and dp2. I have seen adjustments made for that but I would like to see more data.

7. Any general comments about the method?

No

Recommendation for the Method

V. Final Recommendation Do you recommend this method be adopted as a First Action and published in the Official Methods of Analysis of AOAC INTERNATIONAL? Please specify rationale.

Yes. This is a reasonable and specific approach. While I would like to see more specific calibration information, it is not necessary before first action.
