    Abstract: Disclosed is a method for detecting impurities, especially gases in a first material, particularly metallic materials. According to said method, the impurities contained in the first material are transferred into at least one second material, said impurities preferably being concentrated in the second material. The impurities are then detected, preferably quantitatively determined, in the second material. The data obtained in said manner makes it possible to draw conclusions about the presence of the impurities in the first material. Preferably, the concentration of the impurities in the first material is quantitatively determined in an arithmetic fashion.
