Techniques

Chapter 1: Techniques

1.1 The Fundamentals of Light Scattering

The 4-Beam technology leverages the principles of light scattering, a phenomenon that occurs when light interacts with particles suspended in a medium. When a light beam passes through a fluid containing particles, it is scattered in various directions. The pattern and intensity of this scattered light depend on the size, shape, and refractive index of the particles.

1.2 The 4-Beam Approach

The 4-Beam method utilizes four strategically positioned beams of light, each illuminating the sample from a different angle. The scattered light from each beam is then detected by separate sensors. By analyzing the scattering pattern at multiple angles, the system can deduce information about the size distribution, concentration, and refractive index of the suspended particles.

1.3 Advantages over Traditional Methods

Traditional turbidity measurement methods often rely on a single beam of light and measure the total amount of light scattered. This approach can be affected by factors like particle shape and color, leading to inaccuracies. The 4-Beam method overcomes these limitations by providing a more comprehensive analysis of the light scattering phenomenon, yielding more accurate and reliable results.
