NEW unique C18 bonded HPLC column offering alternate selectivity to existing C18 bonded phases
ACE C18-AR is a unique C18 bonded HPLC column from Advanced Chromatography Technologies, which has been developed to provide alternate selectivity to all
existing C18 bonded phases. The phase combines the hydrophobic characteristics of a C18 phase with the enhanced aromatic selectivity of a phenyl phase, enabling the benefits of both interactions to be fully exploited. The phase also exhibits ultra low bleed to ensure LC/MS compatibility and demonstrates excellent temperature and pH stability. Additionally the ACE C18-AR is suitable for use in highly aqueous (up to 100%) mobile phases to enable the retention and separation of polar compounds. At launch, materials are available in 3um, 5um and 10um particle sizes and a full range of column dimensions from high throughput through to preparative scale.

Wonders of Nature Revealed by HPTLC
The latest edition of the CAMAG Bibliography Service, CBS 102, is now available fromCAMAG’s UK distributor,Omicron Research Limited. Containing over 166 extracts of recent publications, CBS is the essential reference bulletin for all those working in the field of Thin-Layer chromatograpy/HPTLC, ensuring readers are the first to be aware of published papers in their field.
CBS 102 features CAMAG’s new TLC-MS Interface, showing
how its revolutionary semi-automatic design can significantly aid identification of unknown substances by extracting compounds from a TLC/HPTLC plate and feeding them into a mass spectrometer for substance identification or structure elucidation. Botanical slimming products come under investigation using HPTLC methods, revealing the extent to which Hoodia Gordinii is misrepresented in product labelling. Studies of nature continue with HPTLC analysis of natural sponges and the world’s oldest tree species, Gingko biloba, for their pharmacological properties.
Copies ofCBS 102 are available, free of charge fromOmicron on
