Elucidating the Working Principle of Turbidimetry
Despite its previously touched upon uses, to fully comprehend the concept of turbidimetry, one must delve into its underlying operational mechanism. This mechanism lies in the principle of light scattering and absorption.
Operational Principle of Turbidimetry
Turbidimetry operates based on the principles of light scattering and absorption. When light from a source passes through a turbid solution in a turbidimeter, the suspended particles in the solution scatter the light. This is the foundation of turbidimetry.
Light Scattering
Light scattering depends on various factors, including the size, shape, and refractive index of the particles, as well as the wavelength of light used. The greater the degree of scattering, the higher the turbidity.
- Particles that are comparable in size to or larger than the wavelength of the light source cause scattering in all directions (Rayleigh scattering).
- Particles much smaller than the wavelength of light scatter light in a manner that is not wavelength dependent (Mie scattering).
Light Absorption
Not all of the light is scattered, some is absorbed by the particles. Light absorption also plays a role in turbidimetry, with darker solutions showing higher values of absorption and peculiar color-related deviations in turbidity measurement.
Calculation of Turbidity
Turbidity is quantified based on the amount of scattered light detected by the photodetector or photodiode in the turbidimeter. The scattered light is converted into an electrical signal, which is then interpreted by the turbidimeter’s processor and displayed as a turbidity value.
Key Components Involved in Turbidimetry
Understanding the key components of a turbidimeter permits more profound insights into turbidimetry and its efficacy.
