“…The combination of the large volume injection (LVI) technique with the capillary GC (CGC) equipped with mass selective detector (MSD) presents a high efficiency separation, selective and sensitive detection, which is very appropriate in trace pollutants analyses in aqueous samples [2] and other matrixes [3]. By increasing the volume of samples, the LOD of the analytical method decreases.…”

“…To meet the sensitivity requirements, a sample preparation procedure providing high enrichment factors for analytes of interest has to be applied. Another approach to such trace analysis is injection of large sample extract volumes [3]. Time of analysis, an important factor in increasing the sample throughput and reducing the cost of analysis, is also of major concern [4].…”

“…Sin embargo es necesario establecer y optimizar algunas de las múltiples variables que inciden sobre la eficiencia de la metodología para la detección e identificación cromatográfica Stan & Linkerhägner, 1996;Engewald et al, 1999;Hada et al, 2000;Heiden et al, 2001;Zrostlíková et al, 2001;Concha-Graña et al, 2002;Teske y Engewald, 2002;Smith, R., 2003). Las inyecciones múltiples se efectúan programando el muestreador automático acoplado al PTV y controlado desde la "ChemStation".…”

“…Este tipo de inyector presenta ventajas relevantes respecto a otros sistemas de inyección de muestra, ya que aporta nuevas alternativas operativas que permiten (Stan & Linkerhägner, 1996;Engewald et al, 1999): el calentamiento del inyector con rampas de temperatura adicionales, la refrigeración del inyector, la utilización del modo "split/splitless" con introducción de muestra tanto en frío como en caliente, el empleo del modo con división a pulsos ("pulsed splits") o del modo sin división a pulsos ("pulsed splitless"), la utilización del modo venteo de solvente para inyectar grandes volúmenes de muestra y posibilitar su concentración en el "liner".…”
