Polycyclic aromatic hydrocarbons (PAHs) are neutral compounds containing multiple aromatic fused rings that are present in fossil fuels and can be formed from the incomplete combustion of organic material. In recent years, it has been well documented that several PAHs can be potentially carcinogenic via exposure or ingestion. The EPA has classified seven PAHs (benzo[a]pyrene, benz[a]anthracene, chrysene, benzo[b]fluoranthene, benzo[k]fluoranthene, dibenz[a,h]anthracene, and indeno[1,2,3-cd]pyrene) as Group. The coupling of reduced liquid chromatography (LC) flow rates with electrospray ionization (ESI) provides enhanced sensitivity and ionization efficiency, and reduced ion suppression in mass spectrometry analysis. NanomateAs the LC flow increases, the ionization efficiency drops owing to the larger sized droplets that lowers the number of available charges per analyze molecule. In order to accommodate micro-flow rates (defined as 1-10μL/min), we have developed a silicon-based ESI chip with various I.D. Sizes (4.1, 5.5, 9.5, and 13.5μm). Como hackear telefono.
