Calculating virtual log P in the alkane/water system (log P(N)(alk)) and its derived parameters deltalog P(N)(oct-alk) and log D(pH)(alk).
J. Med. Chem. 48 , 3269-79, (2005) Growing interest in the use of both the logarithm of the partition coefficient of the neutral species in the alkane/water system (log P(N)(alk)) and the difference between log P(N)(oct) (the logarithm of the partition coefficient of the neutral species in the... |

Evaluation of injection methods for fast, high peak capacity separations with low thermal mass gas chromatography.
J. Chromatogr. A. 1392 , 82-90, (2015) Low thermal mass gas chromatography (LTM-GC) was evaluated for rapid, high peak capacity separations with three injection methods: liquid, headspace solid phase micro-extraction (HS-SPME), and direct vapor. An Agilent LTM equipped with a short microbore capil... |

Development of a standard gas generating vial comprised of a silicon oil-polystyrene/divinylbenzene composite sorbent.
J. Chromatogr. A. 1410 , 1-8, (2015) In this work, a highly reproducible standard gas generating vial is proposed. The vial is comprised of a silicon diffusion pump oil spiked with an appropriate calibration compound, such as modified McReynolds probes (benzene, 2-pentanone, pyridine, 1-nitropro... |

Olfactory psychometric functions for homologous 2-ketones.
Behav. Brain Res. 201(1) , 207-15, (2009) We measured concentration-detection (i.e., psychometric) odor functions for the homologous ketones propanone (acetone), 2-pentanone, 2-heptanone, and 2-nonanone. Under a forced-choice procedure, stimuli were presented via an 8-channel air-dilution olfactomete... |

Novel Methodology for Measuring Temperature-Dependent Henry's Constants of Flavor Molecules.
J. Agric. Food Chem. 63 , 6313-8, (2015) A new methodology is presented to measure water-air partition coefficients (Henry's constants) of volatiles, using APCI-MS. Significant advantages over other Henry's constant determination methods include the short measurement and sample preparation time and ... |

Performance of graphene sheets as stationary phase for capillary gas chromatographic separations.
J. Chromatogr. A. 1399 , 74-9, (2015) This work presents the investigation of graphene as a new type of stationary phase for capillary GC separations. Graphene capillary column (0.25 mm, i.d.) achieved column efficiency of 3100 plates/m determined by n-dodecane at 120 °C. The obtained McReynolds ... |

Development of an enzymatic method to quantify methyl ketones from bacterial origin.
J. Agric. Food Chem. 50(9) , 2471-4, (2002) Methyl ketones are detected in dry fermented sausages in which they contribute to the cured aroma. They have been associated with the inoculation of Staphylococcus carnosus used as starter culture. To evaluate the ability of bacterial starters to produce meth... |

Decarboxylase activity involved in methyl ketone production by Staphylococcus carnosus 833, a strain used in sausage fermentation.
FEMS Microbiol. Lett. 210(2) , 209-14, (2002) Staphylococcus carnosus strain 833, inoculated into sausage, increased the levels of methyl ketones which contributed to the cured aroma. These ketones were predicted to arise from incomplete beta-oxidation followed by a decarboxylation. To check this hypothe... |
