WebThe FWHM for the NMR was in the same range for all the flow cells, as expected due to strong apodization being employed. Considering the FWHM of the DRI, three distinct groups appeared, (a) FC2–FC6 which all had the same FWHM range as the Magritek flow cell. (b) FC7 and FC8 which had a strongly increased FWHM, due to a reduction in the ...
