Foreword

GB/T 19267 "criminal and chemical examination of trace evidence" is divided into 12 parts. --- Part 1. Infrared absorption spectrometry; --- Part 2. UV - visible absorption spectroscopy; --- Part 3. Molecular Fluorescence Spectroscopy; --- Part 4. atomic emission spectrometry; --- Part 5. Atomic absorption spectrometry; --- Part 6. Scanning electron microscopy/X-ray spectroscopy; --- Part 7. Gas chromatography - mass spectrometry; --- Part 8. microscopic spectrophotometry; --- Part 9. thin layer chromatography; --- Part 10. gas chromatography; --- Part 11. High performance liquid chromatography; --- Part 12. Thermal Analysis. This section GB/T Part of 619,267. This Part replaces GB/T 19267.6-2003 "criminal and chemical examination of trace evidence in Part 6. Scanning Electron Microscopy Mirror method. " This portion of the GB/T 19267.6-2003 compared to the main changes are. --- Standard name a "scanning electron microscopy/X-ray spectroscopy"; --- Increasing the term of the environmental electron microscope (this section 3.2,3.18); --- Increasing the principle part of the environmental electron microscope (this section 4.1); --- Instrument composed of indicators made the necessary changes (this part of GB/T 19267.6-2003 and Chapter 5 of); --- Modify the content of the samples prepared (this section 6.4.1,6.4.2, GB/T 19267.6-2003 of 6.3, 6.4); --- Increased working distance describes the content (in this section 7.2.4); --- Modify the sample analysis of the content (in this section and GB/T 19267.6-2003 7.3). This section presents the People's Republic of China Ministry of Public Security. The criminal section of the National Standardization Technical Committee Physical Testing Standardization Technical Committee (SAC/TC179/SC4) Centralized. This section is drafted. Shanghai Public Security Bureau Evidence Identification Center. The main drafters of this section. Ding Minju, Shao Zhiyuan. This part of the standard replaces the previous editions are. --- GB/T 19267.6-2003. Criminal and chemical examination of trace evidence Part 6. SEM/X-ray Spectroscopy

3 Terms and Definitions

GB/T 13966 and established in the following terms and definitions apply to this section. 3.1 Emitted by the electron gun and by electromagnetic lenses focus the electron beam in the magnetic field scanning coils, the sample surface by a certain time, empty In chronological order as the raster scan (also known as point by point scan), received by the detector samples the secondary electron excitation signal, etc., and then by the photoelectric conversion in significant To reflect the observed sample surface looks like an electronic representation of an upper display. 3.2 ESEM is a new scanning electron microscope developed in recent years. Conventional SEM sample chamber vacuum level must be better than 10-3Pa, non - Conductor and water samples need to be plated conductive layer, and ESEM sample chamber through the gas in low vacuum "environment" status (up pressure To 2600Pa), based on gas ionization and amplification principle, non-conductive and aqueous samples can be treated without the surface conduction can be observed directly. 3.3 Beam bombarding a sample with a substance having a certain energy and intensity, according to the particle energy and intensity of the excited sample substance, or a sample Reflective material particle energy and intensity of the relationship diagram (called spectrum) of the sample to achieve non-destructive elemental analysis, structural analysis and surface material Methods of Analysis. 3.4 (SEM/EDS) Micro-beam electron bombardment of the sample, the sample excitation of micro elements characteristic X-ray detection system displays the characteristics of each element microanalysis X Ray energy and intensity graph (called spectrum) and their distribution in the surface of the specimen. ......
