“…It has been demonstrated that the quadrupole ion guides of the ToF-CIMS can significantly change the measured distribution of reagent and impurity ions (Yuan et al, 2016). The PTR-QMS does not have that issue as strongly (modeled and measured cluster distributions are largely similar, as discussed by de Gouw and Warneke, 2007) and therefore we explored the effect of V IC1 , V IC2 , and V DT on reagent ion distribution using the PTR-QMS.…”

“…The H 3 O + ToF-CIMS uses RF-only segmented quadrupole ion guides to transfer ions from the drift tube to a time-of-flight mass analyzer produced by Aerodyne Research Inc./Tofwerk with a mass resolution of 4000-6000 (Bertram et al, 2011). This instrument is described further by Yuan et al (2016). A similar PTR-ToF instrument using quadrupole ion guides has also been recently described (Sulzer et al, 2014).…”

Key indicators: single-crystal X-ray study; T = 293 K; mean (C-C) = 0.002 A ˚ ; R factor = 0.026; wR factor = 0.069; data-to-parameter ratio = 9.6. In the centrosymmetric title molecule, [Mn 2 (C 6 H 2 O 8)(H 2 O) 8 ], the Mn II atom is in an octahedral environment coordinated by six O-atom donors from water molecules and ethane-1,1,2,2-tetracarboxylate ligands. The crystal structure features a three-dimensional hydrogen-bonding network based on a strong and distinctive pattern of O-HÁ Á ÁO hydrogen-bonding interactions.

“…Chemical ionisation with NO + has been used in selected situations to produce differentiation in the reaction products of structural isomers, as demonstrated by Wyche et al 10 , Inomata et al 11 , Yamada et al 12 and Amador-Munoz et al 13 have demonstrated the advantage of using a switchable ionisation mode (NO + /H3O + /O2 + ) in their investigations of some (>C5) straight chain n-alkanes. Arnold et al 14 noted that while NO + produced some product ions with C4 and higher n-alkanes, the low yields observed counted against the use of NO + as a precursor.…”

SummaryAlkanes provide a particular analytical challenge to commonly used chemical ionisation methods such as proton-transfer from water owing to their basicity. It is demonstrated that the fluorocarbon ions CF3 + and CF2H + , generated from CF4, as reagents provide an effective means of detecting light n-alkanes in the range C2-C6 using direct chemical ionisation mass spectrometry. The present work assesses the applicability of the reagents in a Chemical Ionisation Mass Spectrometric (CI-TOF-MS) environments with factors such as high moisture content, operating pressures of 1-10 Torr, accelerating electric fields (E/N) and long-lived intermediate complex formation. Of the commonly used chemical ionisation reagents, H3O + and NO + only react with hexane and higher while O2 + reacts with all the target samples, but creates significant fragmentation. By contrast, CF3 + and CF2H + acting together were found to produce little or no fragmentation. In dry conditions with E/N = 100 Td or higher the relative intensity of CF2H + to CF3 + was mostly less than 1% but always less than 3%, making CF3 + the main reagent ion. Using O2 + in a parallel series of experiments, a substantially greater degree of fragmentation was observed. The detection sensitivities of the alkanes with CF3 + and CF2H + , while relatively low, were found to be better than those observed with O2 + . Experiments using alkane mixtures in the ppm range have shown the ionisation technique based on CF3 + and CF2H + to be particularly useful for measurements of alkane/air mixtures found in polluted environments. As a demonstration of the technique's effectiveness in complex mixtures, the detection of n-alkanes in smoker's breath is demonstrated

Impact of battery electric vehicle penetration and corresponding changes in upstream processes on summer O3 concentrations in Japan

A regional meteorology-chemistry model was used to assess the effects of passenger car conversion to battery electric vehicles (BEV) on summer O3 concentrations in Kanto (Japan's most populous region). Four sensitivity experiments were conducted on different on-road and upstream (power plant and gas station) emission conditions. Daytime 8-h maximum O3 decreased by 3 ppb (5%) and 4 ppb (5%) in urban and inland suburbs, respectively. O3 levels decreased even in urban (VOC-limited regions) because exhaust and evaporative VOC emissions from vehicle and gas stations were reduced effectively (especially alkenes from gasoline evaporation; highly reactive in O3 formation). In the suburbs (NOx-limited regions), reduction of exhaust NOx by BEV shifting was significant, but in urban, even only evaporation measures induced almost the same O3 reduction effect as BEV shifting. The additional emissions from thermal power plants due to BEV night charging contributed little to the next day's daytime O3 on a monthly average basis. However, on some days, pollutants were stored in the upper part of the stable nighttime boundary layer and could affect the surface O3 as the next day's mixed layer development. Depending on the O3 sensitivity regime (NOx-or VOC-limited), additional NOx plumes from rural (urban) power plants tended to increase (decrease) the next day's O3. However, the distribution of the regime changes temporally and spatially. The H2O2/HNO3 ratio was discovered to be a clear indicator for distinguishing regime boundaries and was effective in predicting positive or negative O3 sensitivity to the additional emissions from power plants.
