Small aliquots (N) were used to evaluate the extracts from the different methods.
In addition, Fourier Transform Infrared Spectroscopy (FTIR) was used to double check the preservation of the extracted collagen, and to detect the presence of possible carbon contaminants. 1d: R-EVA 548) the pretreatment was softened in order to minimise collagen loss during the extraction.
In the 1960s and 1970s, gas proportional counters required many grams of bone to produce a radiocarbon date.
Routine measurements today typically require 500–1000 micrograms of carbon (μg C) to produce a high precision date.
The collagen pretreatment protocol routinely applied to Palaeolithic bone at the Max Planck Institute for Evolutionary Anthropology (MPI-EVA, Leipzig, Germany) is based on a modified Longin plus ultrafiltration protocol at CEREGE (Centre de Recherche et d’Enseignement de Geosciences de l’Environnement, Aix-en-Provence, France) is suitable for measuring small archaeological bone samples with sufficient accuracy and precision.
We investigated the effect of sample size reduction at both the pretreatment and gas measurement stages.
The reduction of sample size to enable direct dating of precious bone is therefore a key concern for the archaeological community.The two best teams from Pool C, so the unbeaten Netherlands and Azerbaijan along with two freshly arrived from Ankara – Greece and Bulgaria, met with Bratislava, Slovakia, August 31, 2019.Russia and Belgium lost just one game in the group stage of Euro Volley 2019 Women, but both teams will be playing against each other in the first eight-final in Bratislava.Later on Sunday, Budapest, Hungary, August 31, 2019.The Euro Volley campaign in Budapest goes on, even if the Hungarian team are already out of the competition.
