Ionization of Benzene, Toluene and Xylene via Charge or Proto n Transfer Re action

Benzene, toluene, ethylbenzene and xylene are the compounds c ommonly c alled BTE X. These volatile organic compo unds (VOCs) are widely present in petroleum products, increasing the octan e number [۱]. BTEX are notorious due to the contaminati on of soil an d groundwater and ha ve harmful effects on t he central nervous system. Hence, detecting an d monitoring of these hazardous chemicals in ambient air has been the subject of man y research es. A usual way of detecting those chemicals is ionization and identific ation of their ion in a mass spectr ometer. In t his work we compared t wo methods of atmosp heric pressure chemical ionization, the proton transfer w ith H۳O+ an d the charg e transfer with NO+ for BTEX u sing or an ion mobility spectrometry (IMS).
