Introduction
The standard surface for people to submit samples for chemical analysis of sample handling and delivery to the sample analyzes provide the guidance. Exhausted
Pipe primarily for Auger electron spectroscopy (AES), X-ray photoelectron spectroscopy (XPS) and secondary ion mass spectrometry (SIMS) and write, but these methods
Also be used for other surface-sensitive analytical measurements. AES, XPS and SIMS is typically of a few nanometers (nm) sensitive surface layer thickness. such
Sheet due to incorrect sample handling severely affected [1,2]. Proper handling and preparation of samples for analysis is extremely important
And improper handling can cause the surface composition changes and data can not be trusted.
This standard is buying and who supplied the sample surface analysis provider or surface analysis equipment used. The best approach depends on
In particular sample and the required information, and the present standard of each sample type provides illustrative examples of these types of samples are Sample
Surface owners and analysts commonly encountered. The standard recommendation concerning the origin of the samples on the sample provider, need to address specific issues
Or the required information, and any special sample preparation, handling or transport of the desired method, and surface analysis as soon as possible to discuss personnel.
This standard can not rely on the use of ISO 18116 and independent [4], which is the standard used to guide the analyst surface analysis of the sample system
Preparation and installation.
Surface chemical analysis and processing of samples prior to analysis
1 Scope
This standard specifies the requirements for the processing and storage vessel surface chemical analysis of samples. This standard applies to equipment used in surface chemical analysis
Families understand the special requirements for surface chemical analysis sample handling techniques, especially Auger electron spectroscopy (AES), secondary ion mass spectrometry (SIMS) and
X-ray photoelectron spectroscopy (XPS or ESCA). This standard also applies to other sensitive surface composition analysis techniques, such as TXRF. Correct
In a particular instance, a particular sample, need more attention.

Description 5 standard configuration
Chapter 7 discusses additional matters affecting the composition of the surface will be considered, such as the origin of the samples and the samples previously analyzed. These effects
The file you want to be delivered along with careful sample handling and packaging. Chapter 8 provides the minimum required to make the sample surface contamination of sample treatment
The specific recommendations are also given on during sample handling and transfer to a storage container to maintain and increase sample cleanliness of the range of options
Sample handling methods. Chapter 9 expresses the different sample containers may be used for different conditions, also discussed with the relevant sample storage time,
Humidity and temperature. Chapter 10 and Chapter 11, highlighting the impact on the measurement results of surface analysis sample preparation, implementation of the provisions of sample handling step
When suddenly, the analysis results of samples from owners and analysts to improve the benefit.
