摘要
Apparatus for determining traces of elements in massive samples by optical emission spectrometry comprises an attachment to a Petrey table which is a rotatable sample holder that rotates eccentric to and in gas-tight relation relative to the Petrey table, so that the path of the projection of the electrode on the sample is circular. The material of the sample holder is a self-lubricating material, e.g. polytetrafluoroethylene. The sample holder carries resilient clamps for centering the sample relative to the sample holder.
