Abstract
Optimization of the comparison between the AquaLight LLT cocktail and aqueous samples had been carried out. AquaLight LLT cocktail was mixed with an aqueous sample. The variation ratio between the aquaLight cocktail and the sample were 19: 1; 18: 2; 17: 3; 16: 4; 15: 5; 14: 6; 13: 7; 12: 8; 11: 9; 10:10; 9:11; 8:12; and 7:13. Then, each mixture was analyzed by LSC Hidex 300 SL. Optimization is seen by comparing the highest efficiency which is stated by the TDCR value. The results indicate that the best ratio between AquaLight cocktail and an aqueous sample was 12: 8. The CPM, DPM, and TDCR values from a mixture of 12 mL cocktail and 8 mL sample were 306,400 ± 3,578; 418,000 ± 7,348; and 0.733 ± 0.013.
