We developed a simple and cost-effective method for extracting carbon from dissolved inorganic carbon (DIC) in water samples without a carrier gas. This method only slightly modifies the existing vacuum line for CO2 purification in radiocarbon resear

We studied a suitable procedure for preparing of water samples used in radiocarbon intercomparisons involving dissolved inorganic carbon (DIC). The water samples must have inter-batch consistency and stable 14C concentrations and no sterilizing agent

The preservation of unpoisoned water samples was investigated by radiocarbon analysis with five kinds of natural waters. Although refrigerated and shielded from light, the unpoisoned samples underwent carbon isotopic changes, even after short periods
