“…As a matter of fact, the detection limits often declared from experiments on nitro-PAH standard solutions did not hold when real environmental samples were considered. Among the techniques utilized to detect nitro-PAHs, the most frequently used are gas chromatography combined with, respectively, a thermionic (TID) or nitrogen-phosphorus (NPD) selective detector [13,IS,47,50,59], chemiluminescence-based thermal energy analyzer (TEA) [31][32][33][34] and electron capture detector (ECD) [44,46,57], HPLC with either fluorescence [40][41][42]45], chemiluminescence [36,51,56], or electrochemical [37,42,43,58] detector, gas chromatography-mass spectrometry (GC-MS) in electron impact (EI) [13, 16-19, 32, 34, 35, 59], positive ion chemical ionization (PCI) [9], or negative ion chemical ionization (NCI) electron capture (EC) us. 39,46,48,55,59].…”

A procedure for the determination of nitro-substiruted polynuclear aromatic hydrocarbons (nitro-PAH) on crude air-particulate and soil extracts is introduced. Elimination of purification and fractionation procedures was made possible by the use of both a selective ionization method, such as electron-capture chemical ionization, and a specific fragmentation process, in an experiment of tandem mass spectrometry (gas chromatography-electron capture tandem mass spectrometry). Different mass spectrometric procedures were compared. The best performance was observed when the nitro-PAH molecular ions [M](-) were mass-selected by the first analyzer under multiple reaction monitoring conditions and then fragmented to NO 2 (-) (m/z 46). Detection limits were on the order of hundreds of femtograms, as determined in extracts of real environmental samples. This corresponds approximately to 5-15 pg of nitro-PAH per cubic meter of air sampled. Calibration curves were linear over 3 orders of magnitude. Applications to contamination from motor vehicle combustion and the iron industry are briefly discussed.

“…Many different types of chromatrographic techniques have been tried, from thinlayer chromatography (generally undertaken with fluorimetric detection [1] or even mass spectrometry (MS) [2]) to supercritical-fluid chromatography [3]. There is no doubt, however, that the best possibilities are offered by gas chromatography (GC), with flame ionization detection (FID) [4] or MS [5] and high-performance liquid chromatography (HPLC) with UV-visible detection (MAS), MS [6] or fluorescence [7]. The combination of both techniques [8,9] is also possible.…”

Heated flow-cell for gas phase UV-visible detector in gas chromatography of polycyclic aromatic hydrocarbons

et al. 1999

SummaryA detection system for gas chromatography based on gas-phase, molecular absorption measurements is presented, in which the chromatographic column is directly joined to the spectrophotometer flow cell, without heated transfer lines. To maintain polyciclic aromatic hydrocarbons (PAHs) in the gas phase during detection an aluminium heater was constructed. A mixture of 13 PAHs was then separated and analyzed. Parameters affecting separation (temperature program and carrier gas flow) were studied and a program designed to modify the measurement wavelength during the chromatography. The analytical characteristics of each compound were calculated, obtaining detection limits 0.2-1.5 #g mL q. Given that some compounds overlaped, it was necessary to resolve their peaks mathematicaly. Finally, the method was applied to a certified synthetic mixture, with good results.

“…Many trace organic compounds, especially those present in industrial effluents, have toxic and carcinogenic properties. The determination of herbicides and pesticides in food and water has received much attention (2)(3)(4), and analytical protocols are beginning to focus on health-based limits. Pesticides are introduced into the environment through a variety of compounds such as insecticides, herbicides, and fungicides.…”
