Metal Lab 75/80 V

Analysis of ferrous and non-ferrous alloys

Metal Lab 75/80 can satisfy the most varied requirements, offering at the same time high analytical performance and an extreme easiness of use.

Principle of operation

Metal lab picture Metal Lab is a spark spectrometer aimed at identifying the elements in a conductive and solid sample. A spark is passed through the sample, heating it to a high temperature to excite the atoms within it and identify them.

The spark is located between the sample and the tungsten electrode. The excited atoms emit light at characteristic wavelength that can be detected and studied.

The function of the spectrometer is to separate and to select the spectral lines in order to analyse and quantify them. This operation is done by an optical instrument called Polychromator.

The Polychromator

The polychromator is made of an entrance slit, a diffraction grating and several exit slits that account for the number of elements to analyse.

Photomultipliers tubes are located on every exit slits and, analyse and convert the photon energy collected into electron volts. Then, these electron volts are collected by an electronic acquisition and are automatically processed by the computer.

The computer determines the quantity of elements in the sample. The results can be printed with analysis connections, can be adapted to statistic evaluations requirements and can eventually be dumped to other computers.
