Optimization of sol-gel hybrid mediated hollow fiber-solid phase microextraction for the analysis of selected aldehydes [PDF]

open access: yes, 2014
Hexanal and heptanal are two promising aldehydes that have been found in biological samples of lung cancer patients. In general, aldehydes can be detected in trace level as low as part per billion or part per trillion levels.

Photooxidation of n-Hexanal in Air

open access: yesMolecules, 2001
Dilute mixtures of hexanal in synthetic air (up to 100 ppm) were photolyzed with fluorescent UV lamps (275-380 nm) in air at 298 K. The main photooxidation products, identified and quantitatively analyzed by FTIR spectroscopy, were butene, CO ...

Hexane Air Combustion

open access: yes, 2010
Hot surface ignition and subsequent flame propagation of premixed n-hexane air mixtures are shown in this fluid dynamics video. High speed schlieren photography revealed 3 distinct behaviors of ignition and propagation as a function of mixture composition and initial pressure.

Development of a solid-phase microextraction method for determination of hexanal in mayonnaise-type soy dressing

open access: yesRevista CENIC Ciencias Químicas, 2021
The aim of this study was to develop a headspace-solid phase microextraction (HS-SPME) method combined with gas chromatography for the determination of hexanal as an indicator of the oxidative changes in mayonnaise-type soy dressing.
