 note = {In liquid scintillation counting, a preparation of adequate scintillation cocktail is anessential to obtain an accurate activity of sample and reproducible data. The adequatescintillation cocktail needs to be a homogeneous and colorless liquid phase. In this study,various cocktails with various volume ratios of sample to liquid scintillator were prepared toexamine their homogeneity and color. Both Ultima Gold LLT and Ecoscinti Ultra held watersample above 45 % of cocktail volume with no phase separation and clear liquid. For 1 mol/Lsodium hydroxide solution, both scintillators showed the phase separation at sample fractionof less than 15 %. For acid solutions such as hydrochloric acid and nitric acid, the phaseseparations appeared at less than 26 % of cocktail volume in both scintillators. The quenchingindex, ESCR, of cocktails were measured to estimate the lower limit of detection. For waterand sea water samples, the lower limit of detection was improved with adding sample up to45 % of cocktail volume., Article, 富山大学研究推進機構水素同位体科学研究センター研究報告, 38巻, 2019.12.06, pp.31-40},
