Water quality - Determination of carbon 14 activity - Liquid scintillation counting method (ISO 13162:2011)

ISO 13162:2011 specifies the conditions for the determination of 14C activity concentration in samples of environmental water or of 14C-containing water using liquid scintillation counting.
The method is applicable to the analysis of any organic molecule soluble in water that is well mixed with the scintillation cocktail. It does not apply to micelles or "large" particles (lipids, fulvic acid, humic acid, etc.) that are inadequately mixed with the scintillation cocktail and the water. Some beta energy is lost without any excitation of the scintillation cocktail and the results are underestimated. The method is not applicable to the analysis of organically bound 14C, whose determination requires additional chemical processing (such as chemical oxidation, combustion).
It is possible to determine 14C activity concentrations below 106 Bq l-1 without any sample dilution.

Kakovost vode - Določanje aktivnosti ogljika C-14 - Metoda štetja s tekočinskim scintilatorjem (ISO 13162:2011)

Ta mednarodni standard opisuje pogoje za določevanje koncentracije aktivnosti ogljika C-14 v vzorcih okoljske vode ali vode, ki vsebuje ogljik C-14, s štetjem s tekočinskim scintilatorjem. Metoda se uporablja za analizo katere koli organske molekule, topne v vodi, ki je dobro zmešana s scintilacijskim koktajlom. Ne uporablja se za micele ali »velike« delce (lipide, fulvično kislino, humično kislino itd.), ki so neustrezno zmešani s scintilacijskim koktajlom in vodo. Nekaj beta energije se izgubi brez vzbujanja scintilacijskega koktajla, pri čemer so rezultati podcenjeni. Metoda se ne uporablja za analizo organsko vezanega ogljika C-14, ki za določevanje zahteva dodatno kemično predelavo (na primer kemično oksidacijo, zgorevanje). Koncentracije aktivnosti ogljika C-14 pod 10(nad)6 Bq/l je mogoče določiti brez redčenja vzorca.
