Evaluation and mathematical modeling of processing variables for a supercritical fluid extraction of aromatic compounds from Anethum graveolens
José Jacques Garcez,Fernando Barros,Aline Machado Lucas,Vanessa Barbieri Xavier,Ana Luisa Fianco,Eduardo Cassel,Rubem M. F. Vargas +6 more
TL;DR: In this paper, the authors used a 2 3 factorial design combined with response surface methodology to identify the extraction conditions, using supercritical carbon dioxide as solvent, that maximize the yield of volatile extract from the seeds of Anethum graveolens L. by the use of the response surface method, where the variables pressure, temperature and flow rate of supercritical CO 2 were investigated.

A generalization of the retention index system including linear temperature programmed gas-liquid partition chromatography.
H. van Den Dool,P. Dec. Kratz +1 more
TL;DR: The equation given by Kovats for the calculation of the retention index in case of isothermal operation is transformed to a more general form to include also the case of linear temperature programmed operation and gives the same retention index for both ways of operation.

Gas‐chromatographische Charakterisierung organischer Verbindungen. Teil 1: Retentionsindices aliphatischer Halogenide, Alkohole, Aldehyde und Ketone
TL;DR: In this article, a simple relation exists between the retention index of a compound on a non-polar stationary phase and its boiling point, which is defined as the ratio of the boiling point of the compound to its retention index.
