Developments towards the comprehensive analysis of petrochemical streams

“…The analysis of any one of these phases is very challenging. Typical oil phase samples may contain thousands of compounds. In many cases, complete characterisation of these complex samples is possible with comprehensive two-dimensional gas chromatography (GC×GC), but even with the increase in separation power obtained by comprehensive GC, peak co-elution still occurs when complex samples are analysed. …”

Determination of a robust metabolic barcoding model for chemotaxonomy in Aizoaceae species : expanding morphological and genetic understanding by Hilgart, Amelia

“…Many studies have found that by comparing the vast metabolic fingerprints of closely related species to each other, secondary metabolites tend to be unique to the samples of individual species and are identified in clustering algorithms as the variables responsible for species-specific clustering. …”

An investigation of cyanide-based heap leaching for extracting precious metals from Platreef ore by Mwase, James Malumbo

“…Unlike the cyanide-only system where the passivation was attributed to As build-up at the surface, in the cyanide-ferricyanide system it was attributed to adsorption of unknown reaction products on the mineral surface. Residual samples from batch leach experiments were analysed using X-ray photoelectron spectroscopy and showed samples from the cyanide-ferricyanide tests had less As on the surface than the untreated sample and the sample leached in cyanide. …”
