Title (EN) INCREASING THE SENSITIVITY OF GAS CHROMATOGRAPHY ANALYSIS BY ALLOWING RELATIVELY LARGE SOLVENT VOLUME INJECTIONS WHILE REDUCING SAMPLE LOSS AND SYSTEM CONTAMINATION
(FR) AUGMENTATION DE LA SENSIBILITÉ D'UNE ANALYSE DE CHROMATOGRAPHIE EN PHASE GAZEUSE PAR AUTORISATION D'INJECTIONS RELATIVEMENT IMPORTANTES DE VOLUME DE SOLVANT AVEC RÉDUCTION DE LA PERTE D'ÉCHANTILLON ET DE LA CONTAMINATION DU SYSTÈME
Abstract:
(EN) The disclosure is related to preparing a sample for chemical analysis by evaporating at least a portion of solvent included in the sample. After depositing the sample into a sample container, in some examples, at l east a portion of the solvent can be evaporated. Solvent evaporation can be achieved at room temperature, at an elevated temperature, at atmospheric pressure, or by drawing a vacuum in the sample container, for example. The one or more compounds of interest can pass through a sample delivery port on the sample container into the chemical analysis device for analysis, for example. Preliminary reduction or elimination of the solvent can increase the overall amount of compounds of interest delivered into the chemical analysis device, for example, in some examples, when extra sensitivity may not be needed, less solvent can be used, which can result in a greener analytical technique that is better for the environment.
(FR) L'invention concerne la préparation d'un échantillon pour une analyse chimique par évaporation d'au moins une partie du solvant contenu dans l'échantillon. Après le dépôt de l'échantillon dans un récipient d'échantillon, dans certains exemples, au moins une partie du solvant peut être évaporée. L'évaporation de solvant peut être réalisée à température ambiante, à une température élevée, à la pression atmosphérique ou par formation d'un vide dans le récipient d'échantillon, par exemple. Le(s) composé(s) intéressant(s) peu(ven)t passer à travers un orifice de distribution d'échantillon sur le récipient d'échantillon dans le dispositif d'analyse chimique pour une analyse, par exemple. La réduction ou l'élimination préliminaire du solvant peut augmenter la quantité globale de composés intéressants distribués dans le dispositif d'analyse chimique, par exemple, dans certains exemples, lorsqu'une sensibilité supplémentaire peut ne pas être nécessaire, on peut utiliser moins de solvant, ce qui peut conduire à une technique analytique écologique, qui est meilleure pour l'environnement.
