BS ISO 21270:2004

This standard BS ISO 21270:2004 Surface chemical analysis. X-ray photoelectron and Auger electron spectrometers. Linearity of intensity scale is classified in these ICS categories:

• 71.040.40 Chemical analysis

This International Standard specifies two methods for determining the maximum count rate for an acceptable limit of divergence from linearity of the intensity scale of Auger and X-ray photoelectron spectrometers. It also includes methods to correct for intensity non-linearities so that a higher maximum count rate can be employed for those spectrometers for which the relevant correction equations have been shown to be valid.
