摘要:

This paper deals with the optimal conditions for the detection of15N determined using a four-factor experimental design from [213C-1.315N] caffeine measured with an atomic emission detector (AED) coupled to gas chromatography (GC). Owing to the capability of a photodiodes array, AED can simultaneously detect several elements using their specific emission lines within a wavelength range of 50 nm. So, the emissions of15N and14N are simultaneously detected at 420.17 nm and 421.46 nm respectively.
