An arrangement for analysing the metal content of a metal article which includes a portable probe assembly adapted for application to the article to be analysed, a discharge electrode carried by the probe assembly, means for initiating and maintaining an electrical discharge between the electrode and the article, a radiation spectrometer, and a radiation guide connecting the probe assembly to the radiation spectrometer and providing a radiation path from the discharge to the spectrometer to enable spectroscopic analysis by the spectrometer of radiation emitted from the discharge. The probe assembly includes a casing having a mount for facing to the article to be tested, and a spacing member disposed at the mouth of the casing for contacting the article and locating the assembly in relation thereto, the assembly being so disposed and arranged that in operation with the spacing member contacting the article, the electrode is at an optimum discharge spacing from the article.
Apparatus for analysing the metal content of a solid metal article comprising a portable probe assembly adapted for application to the article to be analysed, a discharge electrode carried by the probe assembly, means for initiating and maintaining an electrical discharge between the electrode and the article, a remote radiation spectrometer, and a flexible radiation guide connecting the probe assembly to the radiation spectrometer and providing a flexible radiation path from the discharge to the spectrometer to enable spectroscopic analysis by the spectrometer of radiation emitted from the discharge, the portable probe assembly including a casing having a mouth for facing to the article to be tested, and a spacing member disposed at the mouth of the casing for contacting the article and locating the assembly in relation thereto, the assembly being so disposed and arranged that in operation thereof with the spacing member contacting the article, the electrode is at an optimum discharge spacing from the article.
A method of analysing the metal content of a solid metal article comprising the steps of placing a portable probe assembly carrying a discharge electrode against the article such that the discharge electrode is located at an optimum discharge distance from the article, striking an electrical discharge between the electrode and the article, transmitting radiation emitted by the discharge via a flexible radiation guide to a remote radiation spectrometer, and analysing the output radiation from the radiation guide by the spectrometer.
