La chromatographie en phase gazeuse (CPG) est, comme toutes les techniques de chromatographie, une technique qui permet de séparer. chromatographie phase gazeuse portable CPG (appareils) / mobile gas chromatography GC instruments · chromatographie phase gazeuse portable CPG. CPG stands for Chromatographie en Phase Gazeuse (French: Gas Phase Chromatography). CPG is defined as Chromatographie en Phase Gazeuse ( French.

Data correspond to usage on the plateform after A variety of applications underlines the high interest of these techniques.

Four major types of hairs were identified, same as described in R. Components of the odours of date palm stem putatively active on the insect’s behaviour were screened by coupled gas chromatography-electroanten-nodetection GC-EAG.

EAG amplitudes to six molecules were higher when the recording electrode was connected onto the internal compared to the external face but the same response profile was obtained on dorsal, central or ventral positions of each club face. Previous article Next article. Wednesday, July 21, – 8: Coupled gas chromatography – chromatograpphie spectrometry GC-MS was used to identify the components of the odours of date palm stem isolated by effluvia collection.

Among all blends, a mixture of ethanol and ethyl acetate A total of molecules were identified in odours from date palm. Bertoncini 1C.


Current usage metrics About article metrics Return to article. Semiochemical-based trapping can play an important role in the integrated management of this pest but the necessity of using plant material as a synergist of the aggregation phero-mone has limited the efficacy and development of the trapping in desert areas.

Have you forgotten your login? A morphofonctional study of the antenna by scanning electronic microscopy SEM and elec-troantennography EAG was realised prior to GC-EAG to verify whether there is an olfactory regionalisation on the antennal club. Initial download of the metrics may take a while.

None of the more complex blends was more efficient. In these cases, the success of trace analysis strongly depends on the separation step.

Thursday, September 30, – 6: Density of basiconic sensilla is higher on female than male antennal club and on internal than external face of the club phsae both sexes. There was a strong variability of the relative effect of this blend with respect to the date palm tissue during three years of experiments.

Trace Analysis in the Petroleum Industry.

Article Abstract PDF The current usage metrics is available hours after online publication and is updated daily on week days. IFP, 60 6 Abstract. This paper aims to point out the interest and the advantages of multidimensional gas chromatography MDGC for performing trace analysis in complex organic mixtures such as hydrocarbon mixtures, petroleum or oil samples, and typical feeds and products from refinery or petrochemical processes. Metrics Show article metrics.


In order to use a synthetic pheromone synergist we screened by field trapping the synergistic effect of molecules identified: Multidimensional gas chromatography could therefore provide an enhancement of detection chromatohraphie leading to a better identification and quantification of trace components.

The mixture of etha-nol and ethyl acetate is a simple, cheap and interesting blend as an alternative for plant baits for R. Vendeuvre 1 and D.


A description of typical instrumentation is given with emphasis on recent developments and improvements in MDGC. The pherosyner-gistic effects of two blends based gazeuss the analyses of odours from date palm, one blend of EAG active molecules and 21 blends based on 52 molecules reported from the literature were studied. Two types of hairs corres-pond to trichoid and basiconic olfactory sensilla. Services Articles citing this article CrossRef
