VELAZQUEZ-GONZALEZ, Julio César; CIBRIAN-TOVAR, Juan; HIDALGO-MORENO, Claudia  and  VASQUEZ-ROJAS, Tito R.. Validación del método de aireación dinámica para la captura de compuestos volátiles de Capsicum spp.. Rev. latinoam. quím [online]. 2011, vol.39, n.1-2, pp.7-16. ISSN 0370-5943.

The Dynamic Method employed to collect Capsicumm spp. Volátiles using gas chromatography with mass selective detector for their quantitation was validated. The validation tests were conduced with seven previously described compounds in Capsicum's volatiles (3-hexanone, 1-bromohexane, 2-ethyl-1-hexanol, 6-methyl-2-hepten-4-ol, p-xylene, D-limonene y 2-ethyl hexyl éster). The method exhibited good selectivity and linearity remained within the 2-120 mg mL^-1 range with correlation coefficients greater than 0.99 for each evaluated compound. The relative standard deviation of factor responses was less than 2%. The validation results show that the method is efficient for extracting volatile compounds with recoveries between 87-98% with R.S.D. less than 10% which is indicative of good accuracy. The standard uncertainty associated with each measurement ranged from 1.17 to1.36 μg: the lowest related to 3-hexanone and the highest to 1-bromohexane.
