Abstract:Analysis of 14 C modern in coral aims to determine the activity of 14 C modern of marine organism. Samples of living coral Porites lobata was taken from inner zone and middle inner zone, Spermonde Archipelago, Indonesia. This research used Liquid Scintillation Counting method. This method used three steps for sample preparation. The first step are physical and chemical washing. In this step, 9 % mass of sample has been removed from impurity. Second steps, CO2 Absorption. The sample entered in modificated absor… Show more
“…14 C analysis by mixing 8 mL sample and 12 mL aquaLight LLT in vial 20 mL [23]. Analysis of 14 C sample from coral Porites Lobata with the ratio between sample and scintillator is 8:12 [24]. Analysis 14 C used 8-12 mL of Carbo-Sorp E and mixture with Permaflour E+ scintillation cocktail and then analysis with LSC [8].…”
Optimization of the comparison between the AquaLight LLT cocktail and an aqueous sample had been carried out. AquaLight LLT cocktail was mixed with aqueous sample. The variation ratio between the aquaLight cocktail and the sample
