Simultaneous identification of different classes of hydrocarbons and determination of nitro-polycyclic aromatic hydrocarbons by means of particle beam liquid chromatography-mass spectrometry

Development of analytical methods for polycyclic aromatic hydrocarbons (PAHs) in airborne particulates: A review

“…Both offline and on-line reduction methods have been reported (Hayakawa et al, 1993(Hayakawa et al, , 2002Murayama and Dasgupta, 1996). In addition, only a few studies have been reported concerning LC-MS of WAHs (Bonfanti et al, 1996). But the sensitivity of LC-MS is not enough for NPAHs at trace levels in environmental samples.…”

Direct Determination of NO2-Substituted Pyrenes by Liquid Chromatography-Atmospheric Pressure Chemical Ionization-Mass Spectrometry

“…In fact, some of the nitro-PAHs have been detected by negative ion chemical ionization, because of the electronwithdrawing effect of the nitro group. 10 In this report, we have presented a method for the direct determination of high mutagenic nitro-PAHs, 1-NP, 1,3-DNP, 1,6-DNP and 1,8-DNP using LC/APCI-MS without pretreatment. The detection technique has been applied to the analysis of urban soil, and 1-NP has been identified.…”

Polycyclic Aromatic Hydrocarbons in the Atmosphere: Monitoring, Sources, Sinks and Fate. I: Monitoring and Sources

“…The major problem to routine LC-MS application is related to the unavailability of rugged and reliable LC-MS interfaces, particularly in the case of PAH analysis. A number of interfaces have been employed for the determination of high-molecular mass PAHs, nitro-PAHs and hydroxy-PAHs in environmental samples, including moving belt (MB), 76 particle beam (PB), 74,77 atmospheric pressure chemical ionization (APCI) 73,[78][79][80] and electrospray interfaces. 78,81 Anacleto et al 82 compared MB, PB and APCI (heated pneumatic nebuliser, HPN) interfaces for the quantitative determination of high-molecular mass PACs.…”
