“…Figure 1A,B demonstrates the ability to baseline-resolve inorganic ion nitrate from organic acids on the AS-17 column using mobile phase conditions suitable for organic acid class separation. Figure 1C shows a separation of the same 25 compound solution on the IonPac AS 17-C column but differs from Figure 1B by using a mobile phase program similar to that reported by Domingos et al 20 The use of a gradient program with a higher initial KOH concentration results in better baseline separation between the aliphatic mono-and diacids, and a gradual increase in KOH concentration across the dicarboxylate region, as shown in Figure 1A,B, results in better separation of the individual diacid ions. Stronger mobile phase conditions are used after the elution of dicarboxylates to elute aromatic and trivalent ions.…”

The structural composition of PM2.5 monitored in the atmosphere is usually divided by the analysis of organic carbon, black (also called elemental) carbon, and inorganic salts. The characterization of the chemical composition of aerosols represents a significant challenge to analysts, and studies are frequently limited to determination of aerosol bulk properties. To better understand the potential health effects and combined interactions of components in aerosols, a variety of measurement techniques for individual analytes in PM2.5 need to be implemented. The method developed here for the measurement of organic acids achieves class separation of aliphatic monoacids, aliphatic diacids, aromatic acids, and polyacids. The selective ion monitoring capability of a triple quadropole mass analyzer was frequently capable of overcoming instances of incomplete separations. Standard Reference Material (SRM) 1649b Urban Dust was characterized; 34 organic acids were qualitatively identified, and 6 organic acids were quantified.

“…Com composição diversificada, o MP pode conter poeira mineral, metais, metalóides, sais marinhos, íons inorgânicos solúveis em água, como os íons Na + , NO 3 -, SO 4 2-, NH 4 + , Cl -, Ca 2+ , Mg 2+ , K + , etc, compostos orgânicos como os hidrocarbonetos policíclicos aromáticos (HPAs), carbono elementar, etc (MURILLO et al, 2013;ZHANG, F. et al, 2013;DESHMUKH et al, 2013;DAHER et al, 2013;ANCELET et al, 2013). A abundância relativa de íons inorgânicos solúveis desempenha um importante papel na determinação da higroscopicidade do material particulado atmosférico (DOMINGOS et al, 2012). Os íons solúveis são associados à formação de partículas, crescimento, processos de evolução, e podem servir como um indicador de substâncias em nível traço de reações nas superfícies das partículas (HAN et al, 2014).…”

Nos últimos anos têm havido uma grande preocupação com os problemas de poluição do ar causados pelas atividades antrópicas, principalmente associados ao lançamento de compostos poluentes em concentrações que podem causar danos ambientais e risco à saúde. Com isso, o presente artigo tem como objetivo apresentar uma revisão dos principais componentes inorgânicos presente na fração inálavel do material particulado atmosférico. Neste contexto, os metais e outros íons constituintes nessas frações podem agir no trato respiratório, promoverem um aumento de doenças carcinogênicas e/ou respiratórias. Conclui-se que, apesar do crescimento dos estudos de quantificação e qualificação da composição química do poluente e bem como a evidência dos efeitos dos componentes à saúde são necessários diversos estudos para caracterizar a qualidade do material particulado em uma determinada região.

“…To enable the determination and quantification of organic tracers following in-flight sampling especially for high altitudes and polar latitudes, a highly sensitive method is needed that allows simultaneous determination of a large number of compounds with low sample consumption. So far in atmospheric aerosol samples, organic markers are determined with GC/MS [19], LC/MS [20], Ion chromatography-conductivity detection (IC-CD) [21] and CE [22]. GC/MS [23,24] is characterized by high sensitivity and efficient analyte separation.…”

“…IC-CD allows a simple, reliable, and inexpensive separation and quantification of water-soluble organic acids. The analysis is limited to ionic or ionizable and hydrophilic species and may suffer from peak overlap of individual compounds [21,26] when a large number of species is present in the sample. Alternatively, CE is used for small carboxylic acids due to its fast separation and good separation efficiency [27].…”

A method using ion chromatography coupled to high-resolution Orbitrap mass spectrometry was developed to quantify highly-polar organic compounds in aqueous filter extracts of atmospheric particles. In total, 43 compounds, including short-chain carboxylic acids, terpene-derived acids, organosulfates, and inorganic anions were separated within 33 min by a KOH gradient. Ionization by electrospray was maximized by adding 100 µL min -1 isopropanol as post-column solvent and optimizing the ion source settings. Detection limits (S/N ≥ 3) were in the range of 0.075-25 µg L -1 and better than previously reported for 22 compounds. Recoveries of extraction typically range from 85-117 %. The developed method was applied to three ambient samples, including two arctic flight samples, and one sample from Melpitz, a continental backround research site. A total of 32 different compounds were identified for all samples. From the arctic flight samples, organic tracers could be quantified for the first time with concentrations ranging from 0.1-17.8 ng m -3 . Due to the minimal sample preparation, the beneficial figures of merit, and the broad range of accessible compounds, including very polar ones, the new method offers advantages over existing ones and enables a detailed analysis of organic marker compounds in atmospheric aerosol particles.
