| The method involves a sample preparation technique through microwave digestion to extract eight metals (Si, Al, Mg, Ca, Fe, Na, K, and Ti) in Portland (SRM 1888b) and Blended (SRM 1881a) cement traceable to NIST followed by spectrometric detection and quantitation via the simultaneous system inductively coupled plasma-optical emission spectroscopy (ICP-OES). A 0.2-gram weight of the materials was prepared for closed-system digestion at 1200W power. After digestion, solutions were diluted using 50-mL dedicated polypropylene laboratory wares (volumetric flasks) and were analyzed. Accordingly, the dilution and calibration patterns were determined. The analyses were performed five times. The detections of Si, Al, Mg, Ca, Fe, K, and Ti following radial mode and Na via axial torch orientation gave satisfactory results. Reproducibility studies were conducted, and ICP-OES configurations were established for each element. The method was developed based on its figures of merit. The procedure was validated with exceptional performance except that it was not robust at a higher sample mass. Operational maintenance procedures were established when many samples were run. Measurement uncertainty estimation is recommended to identify the sources and effects of errors on the measurand. | ||
