Supporting data for manuscript "Single particle ICP-TOFMS on previously characterised EGRIP ice core samples: new approaches, limitations, and challenges"

Single particle inductively coupled plasma-time of flight mass spectrometry (SP ICP-TOFMS) data from the East Greenland ice-core project (EGRIP) ice core, Greenland. The datasets are supporting information for the manuscript "Single particle ICP-TOFMS on previously characterised EGRIP ice core samples: new approaches, limitations, and challenges" accepted for publication at The Cryosphere. Measurements were performed at the NanoMicroLAB, Institute of Chemistry, University of Graz, Graz, Austria with a Vitesse ICP-TOFMS system by Nu Instruments (Wrexham, UK) was operated in SP mode to record and bin mass spectra from 20-240 amu, every 100 µs (4 spectra binning) before saving data to disc while blanking the range 31.5–38.5 amu due to a high signal from the oxygen dimer to avoid signal saturation at the detector. Each sample, blank (frozen MQ water let to melt), and calibration standards were recorded for 100 s. The ICP-TOFMS instrument was equipped with a concentric nebuliser (Glass Expansions) and a cooled (5°C) cyclonic spray chamber. The plasma was operated at 1.35 kW, and the segmented reaction cell was operated with He and H2 flow rates of 12 and 7 mL/min, respectively. This data can be used to obtain the plots shown in the manuscript.
