A review of publications on taking samples and equipment (tools, devices) for this purpose is given. The processes of determination of the amount of impurities in the metals: oxygen, nitrogen, and hydrogen, are considered. The methods of analytical sample preparation passive and active: are systematized. The most representative methods of analytical sample preparation are given and discussed (PWI Laboratory of Gases in Metals). 20 Ref., 5 Tabl.
Keywords: sample, specimen, active and passive preparation, oxygen, nitrogen, hydrogen
