Microbeam analysis - Selected instrumental performance parameters for the specification and checking of energy-dispersive ray spectrometers for use in electron probe microanalysis

This International Standard defines the most important quantities that characterize an energy-dispersive X-ray spectrometer consisting of a semiconductor detector, a pre-amplifier and a signal-processing unit as the essential parts. This International Standard is only applicable to spectrometers with semiconductor detectors operating on the principle of solid-state ionization. This International Standard specifies minimum requirements and how relevant instrumental performance parameters are to be checked for such spectrometers attached to a scanning electron microscope (SEM) or an electron probe microanalyser (EPMA). The procedure used for the actual analysis is outlined in ISO 22309[2] and ASTM E1508[3] and is outside the scope of this International Standard.

Microbeam analysis - Instrumental specification for energy dispersive X-ray spectrometers with semiconductor detectors

<p>ISO 15632 defines the most important quantities that characterize an energy dispersive X-ray spectrometer (EDS) consisting of a semiconductor detector, a pre-amplifier and a signal processing unit as the essential parts. This International Standard is only applicable to spectrometers with semiconductor detectors operating on the principle of solid state ionization. It specifies minimum requirements for such spectrometers attached to an electron probe microanalyser (EPMA) or a scanning electron microscope (SEM). Realization of the analysis is outside the scope of this International Standard.</p>

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
