The system is equipped with a 50 mW, 671 nm solid-state laser (10 mW, 633 nm He-Ne laser available upon request) and an APD detector. Scattered light is collected at both 173° and 90° for size and molecular weight measurements. The 173° detection position automatically adjusts according to the sample’s scattering ability to ensure accuracy across a wide concentration range, while the 90° optics allows size measurements with as little as 3 μL of sample. Scattered light is collected at 12° in the forward direction for zeta potential measurements.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv class=\"ewa-rteLine\"\u003e\u003cspan\u003eThe BeNano system applies Phase Analysis Light Scattering (PALS) technology, combining fast-field reverse (FFR) and slow-field reverse (SFR) data to obtain both the average zeta potential and its distribution.

The scattering intensities of the particles are detected by an avalanche photodiode (APD) and then converted into a correlation function. From this correlation function, a mathematical algorithm can be applied to obtain the diffusion coefficient (D). The hydrodynamic diameter (D\u003csub\u003eH\u003c\/sub\u003e) and its distribution can be calculated using the Stokes-Einstein equation, which relates the diffusion coefficient to the particle size.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan\u003e\u003cimg src=\"https:\/\/files.bettersizeinstruments.com\/images\/20250512\/the_stokes_einstein_equation.jpg\" alt=\"the Stokes-Einstein equation\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan\u003e\u003cimg src=\"https:\/\/files.bettersizeinstruments.com\/images\/20240523\/fighure_intensity_fluctuations_of_small_particles_and_large_particles.jpg\" alt=\"Fighure-Intensity Fluctuations-of-Small-Particles-and-Large-Particles\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch4\u003e\u003cspan\u003e\u003cstrong\u003e2.
