Analysis of the emissions of volatile organic compounds from the compression ignition engine fueled by diesel-biodiesel blend and diesel oil using gas chromatography
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
This paper describes the procedures of the analysis Of Pollutant gases, as volatile organic compounds (benzene, toluene, ethylbenzene, o-xylene, m-xylene and p-xylene) emitted by engines, using high-resolution gas ...
Multiresidue determination of pesticides in honey samples by gas chromatography-mass spectrometry and application in environmental contamination
(Elsevier B.V., 2007-01-01)
A simple and fast multiresidue method has been developed to determine 48 pesticides within the major groups of pesticides (organohalogen, organophosphorous, pyrethroids and organonitrogen) in representative samples of ...

Comprehensive two-dimensional gas chromatography combined to multivariate data analysis for detection of disease-resistant clones of Eucalyptus
(Elsevier B.V., 2013-11-15)
In this paper it is reported the use of the chromatographic profiles from volatile fractions of plant clones - in this case, hybrids of Eucalyptus grandis x Eucalyptus urophylla - to determine specimens susceptible to rust ...
Gas Chromatography-Mass Spectrometry Profiles of Ten Pilea Species (Urticaceae).
(2018-07-24)
The genus Pilea Lindley is the largest among the Urticaceae family. The large size and little
commercial interest of this genus make difficult its taxonomy, with few revisions since Weddell.
Very few revisions have been ...
Simplex optimization of a programmed temperature capillary gas chromatographic separation
(1991-01-01)
The modified simplex algorithm proposed by Nelder and Mead has been used to optimize the separation by temperature programmed capillary GC, of volatile compounds present in alcoholic beverages. An adequate objective function, ...
