a Normalized absorption spectra at 280 nm for SWCNTs separated using hydrogel columns. b Absorption spectra of the SWCNTs eluted with a 1 wt% DOC solution, a 25 mM NaCl/1 wt% SDS mixture or a subsequent 1 wt% DOC solution. c Quantity of SWCNTs eluted by 25 mM of the different solutes. The quantitative difference between NaSCN and NaCl is 6.0 ± 2.0% and that between NaSCN and NaCl/urea is 7.5 ± 0.6%
