This dataset shows the chemical composition of the Orgueil CI chondrite and five Bennu particles, named OREX-803048-0, OREX-803049-0, OREX-803050-0, OREX-803051-0 and OREX-803052-0, from aggregate sample OREX-803014-0 that were dissolved for cosmogenic radionuclide analysis. A small aliquot (~7%) of each of the dissolved samples was taken for chemical analysis by ICP-OES. These splits are named OREX-803048-100 thru OREX-803052-100.

Intermediate ICP-OES Data for ORX-1 thru ORX-7

Methods and Sample processing description, part 1. This section describes dissolution of the samples in HF/HNO3, the addition of Be, Al and Cl carrier solutions and the procedure for taking aliquots of the dissolved sample for ICP-OES analysis.

Methods and Sample processing description, part 2; This section includes details of the ICP-OES analysis, including a description of the standards and elemental lines used for each element.

Methods and Sample processing description, part 3. This section describes how the processed ICP data of are used to check the internal consistency of the ICP measurements by comparing the amount of Be measured by ICP with the amount of Be added as carrier, and how the processed ICP data of Na, Mg, Al, P, S, K, Ca, Mn, Fe, Co and Ni are used to calculate the concentrations measured in the dissolved samples.
