Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS) is a powerful tool for the measurement of low molecular mass compounds of biological interest. The limitations for this method are the volatility of many analytes, possible interference with matrix signals or bad ionization or desorption behavior of the compounds. We investigated the application of well-known and straightforward one-pot derivatization procedures to circumvent these problems. The derivatizations tested allow the measurement and the labeling of alcohols, aldehydes and ketones, carboxylic acids, alpha-ketocarboxylic acids and amines.

Recent data indicate that, in many countries, mobile sources are responsible for the largest portion of emissions of aldehydes, ketones and certain other air toxic pollutants. These air toxic pollutants along with methane are either carcinogenic or pose significant human health threat. These pollutants also add to global warming in a substantial way. This paper gives an overview of their properties, basic chemistry and conditions of formation in internal combustion engines. Again worldwide many countries are promoting alternative fuels to tackle the crisis of traditional fuel. But the impact of this movement toward alternative fuels with respect to toxic emissions has not been well studied. Therefore, in this paper the analysis on the effects of engine operation and fuelling parameters is also reviewed with specific references in gasoline, diesel, natural gas, liquefied petroleum gas, ethanol blended petrol and Biodiesel fuelled engines. This is accompanied by the review of the studies of the performance of exhaust catalytic converters with respect to aldehydes, ketones and methane. Additionally, aldehydes, ketones and methane detection and measurement methods are summarized and analyzed from the view of their applicability to exhaust gas analysis.

“…1−3 MIBK and MET are released into the environment primarily through emissions during their manufacture and usage, including exhaust from petroleumpowered vehicles, industrial processes as waste from heat stacks, coke production plants, land disposal, and ocean dumping of waste. 4,5 Once released into the environment, both MIBK and MET will persist in the vapor phase entering the atmosphere, and they have been detected in southern California air samples. 6−12 In the atmosphere, MIBK and MET are expected to undergo oxidative degradation initiated by hydroxyl radicals, atomic chlorine, atomic bromine, and nitrate radicals, and the initial reaction with the hydroxyl radical is of primary importance because of high concentration of the hydroxyl radical in daytime atmosphere.…”

The kinetics of reactions of 4-methyl-2-pentanone (MIBK) and m-ethyl toluene (MET) with hydroxyl radicals has been studied at a total pressure of 1−8 Torr and 240−340 K using the RR/DF/MS technique. The rate constant for the reaction of MIBK with the hydroxyl radical was found to be essentially pressure-independent in the range of 1−3 Torr. The rate constant for MET reaction with the hydroxyl radical increased with pressure at 1−5 Torr, and a high pressure limit was reached at 5 Torr. At 298 K, rate constants (in cm 3 molecule −1 s −1 ) of k MIBK+OH (298 K) = (1.25 ± 0.21) × 10 −11 and k MET+OH (298 K) = (2.05 ± 0.23) × 10 −11 were determined with n-nonane as the reference compound, while k MIBK+OH (298 K) = (1.25 ± 0.11) × 10 −11 and k MET+OH (298 K) = (1.88 ± 0.17) × 10 −11 were obtained with 1,4-dioxane as the reference compound, where k MIBK+OH was measured at 1 Torr and k MET+OH was measured at 5 Torr. The rate constant of MIBK reaction with the hydroxyl radical was found to be negatively dependent on temperature at 240−340 K, with an Arrhenius expression of k MIBK+OH (T) = (2.00 ± 0.07) × 10 −12 exp[(535 ± 11)/T] cm 3 molecule −1 s −1 . The rate constant of MET reaction with the hydroxyl radicals was also found to negatively depend on temperature at 240−340 K but with nonlinear behavior in the Arrhenius plot.
