A gas chromatograph comparison of the airborne volatiles from black pepper (Piper nigrum) and banana pseudostem (Musa sp) recovered from reverse-phase silica, activated charcoal and Porapak Q traps shows no qualitative differences in the components present.enReverse-phase adsorbentsC18-bonded silicaHeadspace volatilesTrapping; concentrationGC analysisBananaBlack pepperArticle
