This document specifies a procedure by which the intensity scale of an X-ray photoelectron spectrometer that employs a concentric hemispherical analyser can be calibrated using low-density poly(ethylene). This document is applicable to instruments using quartz-crystal-monochromated Al Kα X-rays and is suitable for all instrument geometries. The intensity calibration is only valid for the specific settings of the instrument (pass energy or retardation ratio, lens mode, slit and aperture settings) used during the calibration procedure. The intensity calibration is applicable at kinetic energies higher than 180 eV. The intensity calibration is suitable for instruments that do not have an ion gun for the purpose of cleaning metal specimens in-situ (i.e. Au, Ag, Cu), or exhibit detector saturation when these specimens are measured using standard instrument parameters. This document is not applicable to XPS instruments which do not have a system of charge compensation, or instruments that have a non-linear intensity response. This document is not applicable to instruments and operating modes which generate significant intensity from electrons scattered internally in the spectrometer (i.e. >1 % contribution of scattering intensity to the total spectral intensity).

This document describes the static gravimetric preparation of Class II calibration gas mixtures and describes a method for calculating the measurement uncertainty associated with the amount fraction of each component. In addition to all of the contributions to the measurement uncertainty mentioned in ISO 6142-1, this document also considers the uncertainty resulting from the validation process for Class II mixtures that are not individually verified, as is the case for Class I mixtures. This document extends the uncertainty evaluation described in ISO 6142-1 to include the effects of batch production and the verification process. It provides guidance on how to derive an uncertainty budget that is representative of a particular category of mixtures. Methods for the batch production of more than one mixture in a single process are included in this document. This document is only applicable to mixtures of gaseous or totally vaporized components, which can be introduced into the cylinder in the gaseous or liquid state. Both binary and multi-component gas mixtures are covered by this document. This document is limited to non-reactive molecules/components that are greater than or equal to an amount fraction of 100 μmol/mol.

This document specifies a method for the calibration of the sputtered depth of a material from a measurement of its sputtering rate under set sputtering conditions using a single- or multi-layer reference sample with layers of the same material as that requiring depth calibration. The method has a typical accuracy in the range of 5 % to 10 % for layers 20 nm to 200 nm thick when sputter depth profiled using AES, XPS and SIMS. The sputtering rate is determined from the layer thickness and the sputtering time between relevant interfaces in the reference sample and this is used with the sputtering time to give the thickness of the sample to be measured. The determined ion sputtering rate can be used for the prediction of ion sputtering rates for a wide range of other materials so that depth scales and sputtering times in those materials can be estimated through tabulated values of sputtering yields and atomic densities.

This document is provided to assist in the surface analysis of thin films on materials which are not thought to contain carbon compounds as intended components but for which a C1s peak is observed in the survey spectrum. The films can be those generated on metals and alloys by aerobic or electrochemical oxidation or be those deposited on inert substrates. The procedure described is not suitable for discontinuous deposits of particles on a substrate. With this exception, a simple procedure is provided for identifying the C1s signal from carbon-containing surface contamination. When the C1s peak is identified as arising from an adventitious over-layer the composition derived from the survey spectrum can be corrected for its influence. Recommended procedures are provided in the form of simple Rules structured in the 'If - Then` format with the intention that the information they embody might be utilised by automated procedures in data-systems. The rules provided utilize only information retrieved from the XPS survey scan.

This document provides guidelines that are applicable to bulk and depth profiling GD-OES analyses. The guidelines discussed herein are limited to the analysis of rigid solids, and do not cover the analysis of powders, gases or solutions. Combined with specific standard methods which are available now and, in the future, these guidelines are intended to enable the regulation of instruments and the control of measuring conditions. Although several types of glow discharge optical emission sources have been developed over the years, the Grimm type with a hollow anode accounts for a very large majority of glow discharge optical emission devices currently in use both for dc and rf sources. However, the cathode contact is often located at the back of the sample, in e.g. the Marcus type source, rather than at the front as in the original Grimm design. The guidelines contained herein are equally applicable to both and other source designs and the Grimm type source is used only as an example.
