“…Research showed the comparison cocktail and sample volume, such as 3 H analysis in water sample using 10 mL cocktail and 10 mL water [16], 3 H analysis with the optimum ratio between cocktail and sample, namely 10:10 [17]. Mixture of 2 g sample, 6 g ultrapure water, and 12 mL scintillator [18], 1:2 ratio used for maximizing the counts [15], 3 H analysis using 8:12 ratio (sample water: AquaLight cocktail) in LSC Hidex 300 SL [19].…”
