Cosmogenic nuclides of $$^{10}$$Be and $$^{26}$$Al are used for studies such as estimation of exposure age and erosion rate of rock. In order to measure traces of $$^{10}$$Be and $$^{26}$$Al by accelerator mass spectrometry (AMS) in these studies, reagents with low levels of $$^{10}$$Be and $$^{26}$$Al are needed. In this study, ratios of $$^{10}$$Be/$$^{9}$$Be or $$^{26}$$Al/$$^{27}$$Al in several reagents were compared. The reagents were oxides for evaluation of blank in measurement and standard solutions for atomic absorption spectrometry (AAS) or inductively coupled plasma optical emission / mass spectrometry (ICP) for carrier and evaluation of process blank. The ratios were measured in JAEA-AMS-TONO. The ratios of $$^{10}$$Be/$$^{9}$$Be in the Be oxides and the Be standard solutions were approximately 10$$^{-14}$$$$sim$$10$$^{-15}$$ levels. The Be Standard solutions for AAS and ICP supplied by Merck had lower ratios of $$^{10}$$Be/$$^{9}$$Be than those supplied by Wako and Kanto chemical.
