| Popis: | New nano stationary phase (NSP) capillary columns were evaluated for the analysis of 16 priority polycyclic aromatic hydrocarbons (PAH). To meet the regulatory requirements, the analytical procedures must provide adequate separation and identification of the 16 individual priority PAH. A 12 m conventional diameter NSP column provides fast separation of 16 priority PAH, meeting the USEPA regulatory requirements specified in method 610. The new NSP columns are selective and highly stable with a maximum operating temperature limit of 370°C. The columns have extremely low bleed at the standard working temperature of 325°C normally used for PAH analyses. Due to low bleed, these columns provide higher sensitivity for PAH in GC/FID and GC/MS analysis. Microbore columns with the NSP provide even faster analysis and ultra low bleed. In addition to the 16 priority PAH, the separation of benzo(e)pyrene and perylene from benzo(a)pyrene, and complete separation of dibenzo[a,l]pyrene, dibenzo[a,e]pyrene, dibenzo[a,i]py... |
