The rock samples analysed exhibited various levels of weathering, lithology, and mass. The follow-up mass spectrometry scans revealed Ti impurity in BeO targets which stimulated quantification of Ti in quartz concentrate. The 26Al to 10Be ratios were independent on Ti and Al impurity for samples from the same depositional level. AMS Be current reduction was a function of BeO dilution by TiO2 molecules.
