Abstract. The current study shows a calibration method in gas chromatography (GC) with detection by mass spectrometry (MS) to quantify polychlorinated biphenyls (PCBs) present in transformer oils. The calibration was carried out with a secondary standard composed of a mixture of Aroclors (A1254:A1260), in one to one proportion and a reference standard (1,3,5-trichlorobenzene). This last one was used to evaluate the answer of the MS. The limit of detection of the method was below 10 ìg/mL, with ± 0.002 as deviation in the relative retention time (RRT) and 3.39 % as relative response factor (RRF). Finally, PCBs concentration in oil samples was determined from the calibration data.
Resumen. Se presenta un método de calibración en cromatografía de gases (GC) con detección por espectrometría de masas (MS) para cuantificar bifenilos policlorados (BPCs) presentes en aceites dieléctricos. La calibración se realizó con un estándar secundario compuesto por una mezcla de Arocloros (A1254:A1260), en proporciones (1:1) y un estándar de referencia (1,3,5-triclorobenceno). Este último fue utilizado para evaluar la respuesta del MS. El límite de detección del método fue menor a los 10 ìg/mL, con un ± 0.002 de desviación en el tiempo de retención relativo (RRT) y un porcentaje del factor de respuesta relativa (RRF) de 3.39 %. Finalmente, se determinó la concentración de BPCs en muestras de aceite a partir de los datos de calibración.
