ISO 14594:2014 Guidelines for the determination of experimental parameters for wavelength dispersive spectroscopy
ISO 14594:2014 provides general guidelines for determining experimental parameters related to the primary beam, the wavelength spectrometer, and the sample that must be considered in electron probe microanalysis. It also outlines procedures for determining beam current, current density, dead time, wavelength resolution, background, analysis area, analysis depth, and analysis volume. The parameters obtained from the analysis of a well-polished sample using normal beam incidence are intended for this purpose and can only be indicative of other experimental conditions.

Introduction to ISO 14594:2014
ISO 14594:2014 offers broad criteria for choosing the primary beam, wavelength spectrometer, and sample that need to be taken into account while doing electron probe microanalysis. The methods for figuring out beam current, current density, dead time, background, wavelength resolution, analysis area, analysis depth, and analysis volume are also described. The parameters that can only be suggestive for different experimental settings are those that are derived from the study of a well-polished sample utilizing normal beam incidence. MaTestLab is one of the best testing service providers, with the best network of testing laboratories in the USA to carry out ISO 14594:2014 tests for our clients.
ISO 14594:2014 Test Method
Measurement of Beam Current
A Faraday cup measures the beam current and is placed after the last aperture. If the measurement is done at a different location, the relationship between the designated position and this alternative position must be shown.
Measurement of Beam Density
The diameter of an electron beam is determined by the difference between two standard deviations of the error curve, or the time interval where secondary electron intensity decreases from 84% to 16% of its peak intensity.
ISO 14594:2014 Test Specimen
Specimen Details
The parameters acquired from this International Standard can only be suggestive for different experimental settings and are meant to be used in the analysis of a well-polished sample utilizing normal beam incidence.
Specimen Size
Orthogonality between the electron beam (the optical axis) and the specimen stage is essential to performing a proper quantitative analysis.
ISO 14594:2014 Test Result
In wavelength dispersive spectroscopy, the techniques of microbeam analysis and electron probe microanalysis are essential for setting experimental parameters. These methods ensure precise beam current measurements, data collection, and rectification through the use of a Faraday cup.
