“…In this study, the stable isotope DMS-d 6 was applied as an internal standard surrogate of the DMS analyte to mimic its physical and chemical characteristics. The Henry's law coefficients for DMS-d 6 and DMS have been found to be equivalent within the experimental relative uncertainty of 3.0% relating to this measurement (Ridgeway Jr. et al 1991;Warneck and Williams 2012). The presence of equilibrated DMS-d 6 in a sample can compensate for loss of the DMS analyte during the analysis procedure, thereby improving the precision and quantitative accuracy.…”

“…This was initially assessed by calculating the relative mole fractions of thirteen DMS isotopomers that exist naturally in the environment (Ridgeway Jr. et al 1991). By using the representative natural isotopic composition of the elements H, C, and S (De Laeter et al 2003), the mole fractions of these DMS isotopomers were calculated.…”

An interlaboratory comparison (ILC) was conducted to evaluate the proficiency of multiple laboratories to quantify dimethylsulfide (DMS) in aqueous solution. Ten participating laboratories were each supplied with blind duplicate test solutions containing dimethylsulfoniopropionate hydrochloride (DMSP HCl) dissolved in acidified artificial seawater. The test solutions were prepared by the coordinating laboratory from a DMSP HCl reference material that was synthesized and purity certified for this purpose. A concentration range was specified for the test solutions and the participating laboratories were requested to dilute them as required for their analytical procedure, together with the addition of excess alkali under gas-tight conditions to convert the DMSP to DMS. Twenty-two DMS concentrations and their estimated expanded measurement uncertainties (95% confidence level) were received from the laboratories. With two exceptions, the within-laboratory variability was 5% or less and the between-laboratory variability was ~ 25%. The magnitude of expanded measurement uncertainties reported from all participants ranged from 1% to 33% relative to the result. The information gained from this pilot ILC indicated the need for further test sample distribution studies of this type so that participating laboratories can identify systematic errors in their analysis procedures and realistically evaluate their measurement uncertainty. The outcome of ILC studies provides insights into the comparability of data in the global surface seawater DMS database.

“…The solution was then purged with compressed air to strip DMS out of solution. The sampling manifold used to preconcentrate gas phase DMS stripped from aqueous solutions has been previously described by Ridgeway et al (1991) and will be only briefly described here. After passing through the aqueous sample, moisture was removed from the purge stream by passing the stream through a series combination of Nation dryer and dry ice trap.…”

“…Dimethylsulfoxide concentrations were determined by the method described in this paper. Dimethylsulfide concentrations were determined using an analogous isotope dilution GC/MS method (Ridgeway et al, 1991) employing drDMS as an internal standard. Dimethylsulfoniopropionate concentrations were calculated from the difference between the measured DMS concentrations before and after DMSP was converted to DMS.…”

A method has been developed for determining trace quantifies of dimethyl sulfoxide (DMSO) in aqueous solutions using isotope dilution gas chromatography/mass spectrometry. The method consisted of first reducing DMSO to dimethyl sulfide (DMS), followed by purge and trap preconcentration of DMS. The concentration of DMSO was determined from the signal ratio obtained for the parent ions of DMS and d~-DMS, and the known aqueous concentration of d,-DMSO. The precision of this method was determined to be + 2.9 %, based on replicate DMSO determinations of a test solution prepared by adding isotopically unenriched (I~-DMSO) to distilled water. The detection limit was 0.010 nmoles/L for the sampling conditions used in this study. This method was applied to the determination of DMSO concentrations in both rain and sea water. The concentration of DMSO in rain was found to be in the range of 2 -4 nmoles/L for samples collected at an inland location (Phila, PA) and 8 -11 nmoles/L for samples collected at a coastal location (Lewes, DE). Determination of DMSO in seawater required special sample preparation steps to eliminate positive interferences. A depth profile of DMS, DMSO, and dimethyl sulfoniopropionate (DMSP) concentrations is reported for sea water collected off the coast of Ocean City, Md, in August, 1990

Results from an intensive measurement program studying the marine stratocumulus regime in the eastern North Atlantic Ocean are reported. We observed generally high mixing ratios of sulfur dioxide (SO2) in the region, typically advected within the marine boundary layer (MBL). SO2 mixing ratios ranged from 19 pptv to 1.3 ppbv. Dimethyl sulfide (DMS) mixing ratios also were quite variable, but airborne DMS measurements were never greater than 140 pptv. The mean carbon disulfide mixing ratio was 6.5 pptv. In two intensive Lagrangian experiments, the budgets for SO2 and DMS in the MBL were examined. The observed overnight increase in DMS and the predicted increase based on a budget analysis (using a simple surface flux model) agree within the precision of the data for the first Lagrangian experiment. The photochemical oxidation rates for DMS derived from the budget analysis range from 2.5 to 4.9 μmol/m2 d. Because daytime mixing ratios of NO were seldom larger than 10–15 pptv during both experiments, nighttime oxidation of DMS by NO3 was negligible compared with daytime losses to OH. A positive surface flux is the major term in the DMS budgets. SO2 mixing ratios in the MBL were largely controlled by advected pollution from continental Europe. Deposition of SO2 to the sea surface was the major loss term in the budget analysis. Terms for photochemical production and loss of SO2 could not be independently determined in this analysis, but it is likely these terms were small compared to the surface flux. Based on the observed loss rate for SO2 in polluted European air masses, the mean lifetime of SO2 in the MBL during ASTEX/MAGE is estimated to be 15–18 hours. Our analysis suggests that the Lagrangian experimental design is a valuable tool for isolating chemical change in a dynamic meteorological system, but a budget analysis to determine photochemical production/loss terms is difficult or impossible in the presence of significant pollution. Lagrangian results highlight the potential dangers to chemical interpretation of Eulerian data sets, where advection is often important and needs to be taken into account.
