Solubility parameter determination of cationic surfactants by inverse GC
(Springer Verlag Berlín, 2003-04)
The solubility parameters of cationic surfactants were obtained using the inverse gas chromatographic technique. The surfactants didodecyl dimethyl ammonium bromide, dioctadecyl dimethyl ammonium bromide and dodecyl ...
There is no Time to waste: low-pressure gas chromatography-mass spectrometry is a proven solution for fast, sensitive, and robust GC-MS analysis
(Advanstar Communications Inc., 2020-08)
Low-pressure gas chromatography (LPGC) has been known to be advantageous compared to standard GC since Giddings first described the concept in 1962, but a practical solution for its use eluded analytical chemists until the ...

Permethylated β-cyclodextrin in liquid poly(oxyethylene) as a stationary phase for capillary gas chromatography
(Elsevier Science, 2009-10)
This paper reports the study of poly(oxyethylene) as a solvent for heptakis(2,3,6-tri-O-methyl)-β-cyclodextrin (PM-β-CD) and the potential of these mixtures for constructing enantioselective gas chromatography columns. ...
Dispersive liquid–liquid microextraction and gas chromatography accurate mass spectrometry for extraction and non-targeted profiling of volatile and semi-volatile compounds in grape marc distillates
(Elsevier Science, 2018-04)
The suitability of dispersive liquid–liquid microextraction (DLLME) and gas chromatography accurate mass spectrometry (GC–MS), based on a time-of-flight (TOF) MS analyzer and using electron ionization (EI), for the ...
