Foreword
This standard and ISO 6286. 1982 "overview of molecular absorption spectrometry vocabulary instrument" (in English) of the degree of non-conformity
Equivalent.
This standard replaces GB/T 8322-1987 "molecular absorption spectrometry term."
This standard compared with GB/T 8322-1987, the main technical differences are.
--- Added the following terms. frequency (2.5), a xenon lamp (5.1.2), halogen (5.1.4), the filter (5.2.2), pyroelectric detector release
(5.4.7), mercury cadmium telluride detector (5.4.8), dual wavelength molecular absorption spectrometer (6.6), the anti-deviation of the instrument (7.1.6) and [Light
Gate wavelength selector] Output Power (7.2.13);
--- Terminology "scope of work" instead of "measuring range" (before version 6.1.3, this version 7.1.3), with the "pass band" instead of "band-pass" (the previous version
6.2.1, this version 7.2.1);
--- Symbol increases ν.
The standard proposed by China Petroleum and Chemical Industry Association.
This standard by the National Standardization Technical Committee chemistry.
This standard was drafted. China Inspection and Quarantine Science Research Institute, the Chemical Institute of Standardization.
The main drafters of this standard. Sun Xin, Falls Apart, Wei Jing, Wang Lin.
This standard replaces the standards previously issued as follows.
--- GB/T 8322-1987.
The term molecular absorption spectrometry
1 Scope
This standard specifies the term molecular absorption spectrometry.
This standard applies to molecular absorption spectrometry.
The term radiation and optical properties of 2 related substances
2.1
Belonging to energy propagation of electromagnetic waves in the field. Press wavelength several categories are the following.
Wave length, in units of nanometers (nm)
γ-rays 5 × 10-4 ~ 0.014
Hard X-rays from 0.014 to 0.14
Soft X-ray 0.14 to 10
Far ultraviolet light 10 to 200
UV 200 to 380
Visible light from 380 to 780
Near-infrared light 780 to 3000
The infrared light 3 × 103 ~ 3 × 104
Far-infrared light 3 × 104 ~ 3 × 105
Microwave 3 × 105 ~ 109
2.2
Electromagnetic radiation.
2.3
On the periodic wave propagation direction, the distance between adjacent points in phase between the two waves. For convenience, usually in the maximum or minimum value of the waveform
At the measurement. See Figure 1.
Figure 1 a schematic view of the measuring wavelength
Note 1. The infrared wavelength units available μm (microns).
Note 2. the refractive index of the medium in the wavelength equal to the wavelength in vacuum divided by the medium. Without explanation, generally refers to a vacuum wavelength.
2.4
The number of waves per centimeter contained, that is equal to the reciprocal of the wavelength. Unit. cm -1 (cm-1)
