I am searching for new easy-to-use, solid lab standards for delta D measurement via thermal conversion EA-IRMS. I thought that a suite of common polyethylene or polypropylene samples with different delta D values would be good candidates. Therefore, I am currently collecting all the plastic garbage that passes my way to sort out samples with enriched or depleted delta D values which could serve as lab standards for delta D normalization. However, I have not yet started any measurements.
Here are my questions:
1. Has anyone done this before and, if yes, provide some hints where I could look for light or heavy (in terms of delta D) plastic (PE or PP)?
1. Since I do not know much about the production process of synthetic polymers, I have no idea about the chances of finding plastic with largely differing delta D values. What would you expect? Are there certain products where you would expect distinctly low or high delta D values?
I am very much looking forward to answers or guesses!!!
