EJ-351

 

EJ-351

 

EJ-351 is a scintillation cocktail based on highly purified dioxane and is identical to the original NE-220. It is intended primarily for alpha and beta detection in counting water-based solutions of sugars and salts as well as body fluids such as urine and blood serum. It can also be used to assay tritiated water. Since it is dioxane-based, it offers very high light output and is relatively resistant to quenching.  Water can be added to EJ-351 in quantities up to 10% of the final solution mixture.
