Icap 7000 series icp aes spectrometer

Concentrations of Pt were measured using the Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES). Blood samples were mixed with 200 µL of H₂O₂ and 500 µL of 69% superpure HNO₃, then heated at 100 °C for 10 min in a water bath. The samples were then cooled, diluted with superpure water to a final volume of 5 mL, filtered through syringe filters (pore size 0.22 µm), and measured for Pt content using a Thermo Scientific iCap 7000 Series ICP-AES spectrometer. The spectrometer was previously calibrated for quantitative analysis with four standard solutions containing known concentrations of Pt: 0.001, 0.01, 0.1, and 1.0 mg/L. The calibration line showed a correlation coefficient (r) greater than 0.99 for the measured element. The results were the average of three different measurements, and the Pt final concentrations were expressed as mg/L.
