Binary gradient elution of semiconducting single-walled carbon nanotubes by gel chromatography for their separation according to chirality

, 2012
Binary gradient elution is used for the rapid separation of semiconducting (s-) single-walled carbon nanotubes (SWCNTs) with single or few chiralities using single-column sephacryl gel chromatography. It is found that single-component elution with sodium

Reproducibility of gel‐chromatography

International Journal of Peptide and Protein Research, 1984
We think it worthwhile to other experimenters to mention the following observations. Recently it was noted that gel chromatographic separations of the five fragments resulting from the degradation of cytochrome c by bromocyanogen became dependent on the batch number of the gel. This dependency concerns only separations of unprotected fragments, using 7%

Gel chromatography of heparin

Journal of Chromatography B: Biomedical Sciences and Applications, 1981
It is assumed that heparin is a heterogeneous substance. In order to further investigate the purification of heparin, a column chromatographic technique for the fractionation of heparin is described using various diameters of bead form cross-linked dextran gels and an automated apparatus. It was observed that Sephadex G-50 resulted in the separation of
