Sample handling for electronic nose technology: State of the art and future trends

摘要: Abstract Recent advances in the sample handling techniques as part of analytical workflow analysis with electronic nose systems are reviewed. Classic approaches headspace well advanced methods enrichment and dynamic separation considered summarized. The efficiency application different sampling for specific tasks is demonstrated. Special attention paid to present trends searching aimed replace time-consuming expensive preparation procedures alternative techniques, including development sensors arrays adaptive selectivity profiles, creation sensor interfacial architectures tunable adsorption properties, experimental data coding use classic spectroscopic “virtual” array formation.
