- “Line” designates the detected X-ray line; Conc. is the calibrated concentration of the element in weight %; Sigma is one standard deviation; and RSD is the relative standard deviation expressed in %. The results should be interpreted with some caution because the DCCR calibration is performed with the NIST SRM 610 whose matrix is different from that of the sample
