Fast analysis of 29 polycyclic aromatic hydrocarbons (PAHs
2015年8月12日 · This fast, sensitive and reliable method is the first UHPLC-APPI-MS/MS method capable of simultaneously analyzing 29 environmentally and toxicologically important PAHs and nitro-PAHs.
Gas chromatography-mass spectrometry (GC-MS) is well suited for the analysis of OCPs, PAHs, and PCBs. Single quadrupole GC-MS has offered the opportunity for the environmental laboratory to increase selectivity for these analytes over that of classical detectors, such as UV and fluorescence detectors in HPLC and ECD and FID detectors in GC.
by multiple techniques, GC/MS provides high selectivity and sensitivity for trace levels of PAHs in water, soil, and other complex matrices. Although helium is generally considered the best carrier gas for GC/MS analysis, its recurring shortages have increased demand for using hydrogen as …
