<Summary>For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.848530"! ** Mass: Mettler-Toledo UMT2 after 48 h equilibration of the impactor foils at 20 °C and 50 % rel. humidity.
Extraction: Parts of the Al impactor foils were extracted in 2 ml high purity water (&gt;18.1 ohm cm). 15 min: shaking - 15 min ultrasonic bath - 15 min shaking.
IC (cations): Metrohm with WATERS IC-Pak C M/D Column; eluent: 0.1 mM EDTA, 3.0 mM HNO3
IC (anions): To determine bromide along the high chloride concentrations of the sea salt, a special column Metrosep A Supp 5 (Metrohm) was used in a Compact IC 761 (Metrohm LTD, Switzerland) to measure the anions Chloride, Bromide, Nitrate, Sulfate, Oxalate (Eluent: 1mM NaHCO3/3.2 mMNa2CO3, flow rate:0.7 ml/min)
CE: Spectra Phoresis 1000 (TSP, USA), equipped with fused silica capillary (length:70 cm, 63 cm to detector, ID: 75 µm) For separation of dicarboxylic acids and methane sulfonic acic, the capillary was filled with a background electrolyte consisting of 10 mmol/l p-aminobenzoic acid, 8 mmol/l diethylenetriamine, and 3.5 mmol/l aqueous sodium hydroxide (pH = 9.6). After hydrodynamic injection at 10.3 kPa for 34 s, a separation voltage of 30 kV was applied. Indirect detection was performed at 254 nm.
OC/EC: modified VDI2465 Bl.2 using a C-mat 5500 at Tmax = 650 °C (OC: 8 min at 650 °C under high purity Nitrogen; EC: 8 min  at 650 °C under high purity Oxygen)
OM was calculated according to the paper of Turpin et al. 2000 (doi:10.1016/S1352-2310(99)00501-4) from OC using a factor of 2.
TXRF: Bruker S2 Picofox on quartz wafers after 1.5 h cold plasma pyrolysis to eliminate the Nuclepore substrate.</Summary>
