Mass spectrometric study of cutaneous volatiles by secondary electrospray Ionization

Mass spectrometric study of cutaneous volatiles by secondary electrospray Ionization

P. M-L Sinues

We investigated the volatile organic compounds emanated from the hand of two individuals, on-line by secondary electrospray ionization-mass spectrometry in positive ionization mode. The background ambient air is continuously sampled, ionized and readily mass analyzed. When the probe samples above the headspace of the hand of two subjects, several peaks …

On-line Detection of Human Skin Vapors

On-line Detection of Human Skin Vapors

P. M-L Sinues, J. F. de la Mora

Vapors released by the skin in the hand of one human subject are detected in real time by sampling them directly from the ambient gas surrounding the hand, ionizing them by secondary electrospray ionization (SESI, via contact with the charged cloud from an electrospray source), and analyzing them in a mass spectrometer with an atmospheric pressure source (API-MS).
