General requirements:
1) PLC grade Mobile Phase (here: HPLC grade THF) is to be provided prior to analysis.
2) For aqueous GPC a 0.1M Na-nitrate solution will be prepared by BA which will be used by you to dissolve your samples in.
3) Absolutely no polyolefins or PET samples!
4) Samples have to be completely dissolved in the solvent as they will be filtered prior to analysis. MW of sample has to be > 4000 Dalton for GPC.
5) PEG/PEO stds. are used for aqueous.
6) PS stds. are used for THF.
(Please note: only aqueous or THF columns are available for testing!)
