When compared with an ODS column having good surface coverage and operated with pure methanole eluent, the Hypercarb column exhibits similarities in some respects and dissimilarities in others. Methylene homologues separations look similar on ODS and
Separation of Sulphonium Salts by Ion Chromatography: Five- and Six-Membered Cyclic Sulphonium Salts

Several cyclic 5-and 6-membered sulphonium compounds were separated by ion pair chromatography on a opti-dbb ion pair column. The salts show specific retention behavior when using different mixtures of acetonitrile and aqueous sodium perchlorate solu

The RPLC retention of 1,n-halo(alkylthio)alkanes on an ODS phase with methanol/water (95%/5%) has been investigated. Replacement of a methyl group in a dialkyl sulphide R-S-R by a halogen atom X, to yield the title compounds X-(CH2)n-S-R, generally r
