“…Similarly, ammonium chloride [ Twomey , 1971b; Pinnick et al , 1987] and ammonium sulfate [ Brooks et al , 2002] evaporate below 150°C. Organic nitrogen [ Daisey and Gundel , 1991], terpen [ Grosjean et al , 1994], dioctyl phthalate [ Husar and Shu , 1975], and organic carbon from ocean [ Pueschel et al , 1973] also evaporate in this temperature range. The second temperature range (II) corresponds to the evaporation of ammonium sulfate [ Twomey , 1971b; Clarke et al , 1987; Hudson and Da , 1996; O'Dowd and Smith , 1993b; Smith and O'Dowd , 1996], ammonium bisulfate [ Clarke , 1991; Daisey and Gundel , 1991], ammonium nitrate [ Daisey and Gundel , 1991], diesel exhaust [ O'Dowd et al , 1992], and secondary organic carbon [ Tanner et al , 1982; Ohta and Okita , 1984; Daisey and Gundel , 1991; Steiner et al , 1992; Grosjean et al , 1994].…”

“…Measurement of the volatility of organic aerosol was initiated by Daisey and Gundel [1991], who heated indoor aerosol and measured organic carbon and nitrogen emissions. Steiner et al [1992] found that particles in the exhaust of spark ignition engines exhibited significant changes in size, structure and surface chemical composition with increasing temperature, whereas black carbon was unaffected up to temperatures of 325°C.…”

1] The composition of cloud condensation nuclei (CCN) was determined by thermal analysis, whereby CCN and aerosol particles were heated to temperatures up to 500°C. The CCN were observed in the urban atmosphere of Nagoya and in the coastal atmosphere of Mikuni, Japan. Automobile exhaust particles were also analyzed to examine the contribution of anthropogenic organic materials to CCN. The thermal analytical behavior of CCN at Nagoya and Mikuni showed that more than 80% of the total number concentration of CCN evaporated at or below 300°C and the concentration of CCN remained almost constant between 300°and 500°C. Thermal curves for inorganic ions such as NH 4 + , NO 3 À , and SO 4 2À were similar to those for CCN, whereas the thermal curve of sea salt particles and total carbon (organic plus soot) particles were different from CCN. The results suggested that inorganic materials such as ammonium sulfate and ammonium nitrate contributed greatly to the CCN in the urban atmosphere and ammonium sulfate contributed considerably to the CCN in the coastal atmospheres. Anthropogenic organic materials, which evaporated below 300°C, contributed considerably to the CCN, whereas soot particles contributed hardly to the CCN.

“…A limited number of studies have explored the combustion-based approach for the determination of nitrogen in aerosols. Dod and his colleagues have demonstrated the feasibility of combining thermal evolution techniques and chemiluminescence detection for the measurement of aerosol nitrogen (Dod and Novakov 1982;Dod et al 1984;Daisey and Gundel 1991), but no detailed method characterization and validation is available in their reports. More recently, Stolzenburg and his coworkers (Stolzenburg and Hering 2000;Stolzenburg et al 2003) reported an automated method for one group of aerosol nitrogenous compounds, i.e., nitrates.…”

An aerosol nitrogen analyzer has been developed for determination of total nitrogen (TN) content in aerosols collected on a filter substrate. It uses rapid thermoevolution of nitrogenous species at 800• C in a 2.5% O 2 /97.5% He carrier gas. Evolved nitrogen is oxidized to nitrogen oxides on a manganese dioxide catalyst, converted to nitrogen monoxide on a molybdenum catalyst, and quantified with a chemiluminescence detector. The analyzer is built upon components of two commercially available instruments, a thermal aerosol carbon analyzer and a chemiluminescent NO x analyzer. This system is able to provide fast (3 min per sample) and highly sensitive (a detection limit of 26 ng N) TN measurements for aerosol samples of a small size (∼1 × 1 cm 2 ) without any pretreatment. When the aerosol nitrogen analyzer was properly calibrated by ammonium sulfate, excellent agreement was obtained between TN measurements of twelve aerosol samples by the aerosol nitrogen analyzer and those obtained from an elemental analyzer. This instrument provides a useful and convenient tool for characterization of the organic nitrogen (ON) pool in atmospheric aerosols. The ON concentrations in the twelve aerosol samples, calculated from the difference between TN and the sum of the inorganic nitrogen species determined by ion chromatographic analysis, were found comparable in magnitude to particulate nitrate-N. The contribution of ON to TN ranged from 1.7% to 54% for the limited set of test samples. While twelve samples are insufficient to draw general conclusions about the relative distribution of ambient aerosol nitrogen species, they have demonstrated the applicability of the new method to ambient aerosol characterization and exposed a potential limitation in deriving at ON concentrations by taking a sometime small difference between two large numbers (i.e., TN and inorganic nitrogen). Differentiation of organic and inorganic nitrogen using thermal methods is also explored and found not to be feasible.
