(General mineral infrared spectrometry) People's Republic of China Entry-Exit Inspection and Quarantine Standards General mineral infrared spectrometry Issued on. 2014-04-09 2014-11-01 implementation People's Republic of China The State Administration of Quality Supervision, Inspection and Quarantine released

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard is proposed and managed by the National Certification and Accreditation Administration Committee. This standard was drafted. Tianjin People's Republic of China Exit Inspection and Quarantine, Thermo Fisher Scientific China Limited. The main drafters of this standard. From Madrid, Wu Suru, any sea, Hao Chen Xin and Gao Bo, Yang Jian, Du Bin. General mineral infrared spectrometry

1 Scope

This standard specifies the qualitative analysis Fourier transform infrared spectrometer to identify the import and export of inorganic minerals General. This standard applies to the use of Fourier transform infrared spectroscopy method for qualitative analysis of inorganic mineral Importers, wave number range 4000cm-1 ~ 400cm-1.

3 Terms and Definitions

GB/T 6040 and GB/T 8322 defined by the following terms and definitions apply to this document. 3.1 Minerals IR main features themaincharacteristicsofinfraredspectraofmineral Minerals IR main display vibration and anions in the envelope of a certain crystal field. In addition there is a group within the vibration, there are external vibrations (or lattice Vibration), including lattice relative translational and rotational group structure unit. Infrared spectroscopy confirmed that a large number of experiments, each group is not Substantially the same frequency in the same compound, that each group has its own characteristic absorption frequency. These groups may decide frequency vibrational modes and mineral red The outer contour of the main spectrum, infrared spectrum are the main features of the mineral. 3.2 Minerals IR main object infraredspectroscopyofmineralsmainresearchobject Mineral-containing complex anion of a mineral IR main object of study. 3.3 "Closed" group "closed" group Most minerals such as carbonates, phosphates, silicates and borates and other internal groups predominantly covalent bonds between atoms within a group bonding ratio Between larger groups, it is possible the group as a separate unit, the crystal structure can be divided complex anion group, known as the "seal Closed "group. 3.4 "Open" group "opened" group Some oxides, sulfides and halides, the group internal strength ionic bond or less, that is too close to the crystal structure of the complex anion Group, referred to as "open" group. ...
