NANBEI INSTRUMENTS Spectrophotometer
一、Chapter 1 Principles, uses and characteristics
1.Principles
Principle Material is selective for the absorption of light, under the irradiation of light, to produce the absorption effect. Different substances have different absorption spectra. When a monochromatic light passes through the solution, its energy will be weakened due to its absorption, and the degree of light energy weakening and the concentration of the matter will show a certain proportion. This series of instruments performs a qualitative and quantitative analysis of the samples based on the colorimetric principle, which complies with the Lambert-Beal law in a certain range of concentrations:
A=lg1/T=kCL T=I/I0
among: A: absorbance
T: transmissivity
I: Through the light transmission intensity
I0: the incident light intensity
K: Absorption coefficient of the sample
C: Concentration of the samples
L: Length of the light passing through the sample。
2.Use
This instrument can make qualitative and quantitative analysis of sample substances in the ultraviolet and visible spectrum areas, and can be widely used in medicine and health, clinical testing, biochemistry, petrochemical, environmental protection testing, food hygiene and quality control and other departments, and can be used as the teaching demonstration and experimental instrument of relevant courses in colleges and universities。
