Different AMS labs may have slight variations in the procedure of chemical pretreatment, but they often use the same chemicals in treating bone samples. Additionally, the age of the individual might play a role in the resistance of the tissue against degradational factors. A new and compact system at the AMS laboratory in Bucharest.
