Process for Simultaneously Sampling Metals for Spectrographic and Chemical Analysis

Volume 14, Number 2 (April 1960) Page 53-54

Kennedy, W.R.; Smith, R.N.


In every producer's plant where molten metal must be sampled for spectrographic and chemical analysis, there exists a sampling problem. In fact, it has been said that the sampling problem is as old as analysis itself. The sample produced for one laboratory almost never satisfies the other laboratory as to physical size or metallurgical condition. In addition, the two samples may be taken at different times during a heat and as a result, different compositions will be sent to the two laboratories with the same identification. The resulting conflict between the two laboratories making the same determination on the "same" does not promote good relations between laboratory personnel.
