  1. The value was computed as the mean (the measurement was repeated three times) percentage deviation from the expected value for an independently prepared RM. The selected spectral lines allow covering the range of concentrations of the samples in this work. Also reported are the LODs and LOQs (nblanks = 4). The plasma viewing for all the lines is axial
