Two different samples of aluminium alloy (Al-Mg-Si) were measured with the DSC 404 F3 Pegasus^® during heating and cooling. Melting and also solidification of the alloy is clearly visible in the measurement results. The differences between the two different samples, however, are small. The characteristic temperatures (onset, peak) agree all within 0.3 K. The differences in the peak areas are less than 1% for both heating and cooling. The good agreement between the two measurement results demonstrates the excellent capability and reproducibility of the DSC 404 F3 Pegasus^®.
