متن کاملPeroxyacetyl nitrate (PAN) and peroxypropionyl nitrate (PPN)
Atmospheric Chemistry and Physics Discussions This discussion paper is/has been under review for the journal Atmospheric Chemistry and Physics (ACP). Please refer to the corresponding final paper in ACP if available. Abstract Peroxyacetyl nitrate (PAN) and peroxypropionyl nitrate (PPN) were measured sequentially in situ by an online gas-phase chromatograph with electron capture detector at urba...
متن کاملReaction of peroxyacetyl nitrate with glutathione.
Peroxyacetyl nitrate reacts with the sulfhydryl groups of reduced glutathione. Thioester formation accounts for as much as 50% of the reacted sulfhydryl groups. As much as 60% of the reacted sulfhydryl groups can be accounted for as oxidized glutathione. The stoichiometry of the reaction is approximately 3 moles of sulfhydryl reacting per mole of peroxyacetyl nitrate, and this stoichiometry is ...
متن کاملThe Quantum Yield of N03 from Peroxyacetyl Nitrate Photolysis
Peroxyacetyl nitrate (PAN) vapor was photolyzedat 248 nmandthe N03 photoproduct wasdetected bylaser induced fluorescence. Thequantum yield fortheproduction of N03 was determined by comparison to N 205 photolysis data taken under identical experimental conditions. Contributions to the observed laser induced fluorescence were found to arise from excited state photoproducts such as N02* . The exci...
متن کاملAccuracy, standardization, and interlaboratory calibration standards for foraminiferal Mg/Ca thermometry
[1] The use of liquid and solid standards for foraminiferal Mg/Ca and Sr/Ca determinations and interlaboratory calibration has been investigated. Preparation of single element standard solutions from primary solid standard material enables the preparation of mixed standard solutions with Mg/Ca and Sr/Ca ratios of known accuracy to better than 0.1%. We also investigated commercial reference mate...
