Advancements in data acquisition technologies and the desire for rich data has led to an increase in the size of data collected from modern analytical instruments. With the aid of chemometric techniques, researchers are still able to glean more useful information from these kinds of data than...

Air pollution is a global issue which has an impact on various aspects of life with a vast range of pollutants being monitored with different methods. One class of pollutants is the volatile organic compounds and their presence in the air requires improved methods to accurately report the...

Metabolomics is an ‘omics’ field, which involves the comprehensive characterization of metabolites using analytical chemistry technologies and statistical methods to interpret the results. The term metabolomics was coined about two decades ago as an analogy to other precedent omics approaches:...

Fire is a highly destructive force which causes significant loss of life and property each year, part of which arises from criminal activity through use as a weapon and to destroy evidence of other crimes. Administrations which provide codes and standards for public safety generally mandate that...

Thermodynamics-based predictive models of retention in gas chromatography and comprehensive two-dimensional gas chromatography have been demonstrated to provide high prediction accuracy across a wide range of separation conditions. They generally predict better than retention index-based models...

The profiling of alkyl phosphates in petroleum samples is of particular interest to refineries that process conventional crude oil derived from the Western Canadian Sedimentary Basin and other similar geologies. This is due to alkyl phosphate-based additives used during crude oil recovery...

Arson is one of the most challenging crimes for forensic scientists to investigate. The variability in the composition of ignitable liquids, including changes in chemical composition during and after the fire, and the presence of pyrolysis products generated from burning substrates yields a very...

Three parameter thermodynamic predictive models have been shown previously to provide superior accuracy in the prediction of gas chromatographic retention times in comparison to other forms of modelling such as retention indices. However, these models suffer from the need for extensive...
