ASTM E415 PDF

The atomic emission spectrometric analysis provides to identify and quantify within a material a series of elements, present within certain assigned concentration certificates. The suitably polished test samples are analyzed by generating an electric arc fired on their surface by the spectrometer electrode and subsequent light emission. Atomic spectra, different for each element, cause the emission of certain wavelengths, having observed the quantification of the chemical composition of the material. To overcome the possible problem of absorbing radiation through the air, it is diffused by the objective into the scintillation chamber.

The atomic emission spectrometric analysis provides to identify and quantify within a material a series of elements, present within certain assigned concentration certificates.

The suitably polished test samples are analyzed by generating an electric arc fired on their surface by the spectrometer electrode and subsequent light emission. Atomic spectra, different for each element, cause the emission of certain wavelengths, having observed the quantification of the chemical composition of the material.

To overcome the possible problem of absorbing radiation through the air, it is diffused by the objective into the scintillation chamber. Our instruments are listed which are able to detect the presence of the elements in the different materials are shown below.

The internal laboratory procedures relating to the spectrometric analysis of a vacuum atomic emission of carbon and low alloy steels, stainless steels, cast iron, cobalt alloys, nickel alloys and titanium alloys have been validated by Accredia.

The specimen thickness can vary significantly according to the design of the spectrometer stand, but a thickness between 10 mm and 38 mm has been found to be most practical. It is designed for chill-cast, rolled, and forged specimens.
