| Popis: | Corrosive changes of transversely heated graphite atomizer (THGA)-tube and platform surfaces were studied by scanning electron microscopy in combination with tube lifetime measurements under recommended conditions for vanadium determination. This was done for the four mineral acid matrices HNO3, HF, HCl and HClO4. Rising corrosion and reduced tube lifetime are observed for these matrices in the sequence HNO3 |
