Laser Diffraction Particle Size Analyzer Bettersize Instruments Bettersizer 2600 Laser Diffraction Particle Size Analyzer

Bettersize Instruments Ltd. Bettersizer 2600 Laser Diffraction Particle Size Analyzer

• Bettersizer 2600 is a powerful and versatile particle size analyzer operating according to laser diffraction methods and complying with the ISO 13320 standard.
• Our three patented technologies open up new possibilities for almost every industry and application, with a wide measurement size range that allows users to examine materials from 0.02 μm to 2600 μm. With its modular design, both wet and dry measurements can be performed in a single instrument and software, ensuring data integrity.

OPTICAL SYSTEM PROPHECIES

• Stable optical system with high resolution and sensitivity.
• High signal-to-noise ratio for ultra-fine particles.
• Wide measurement range: from 0.02 μm to 2600 μm.
• Single laser system (635 nm) – no mixture of different wavelengths in the spectrum.

High Resolution
The Bettersizer 2600 can separate different materials with various particle sizes in a single measurement due to its high resolution.

High Sensitivity
By incrementally adding one sample to another, the Bettersizer 2600 shows changes in particle size distribution along a curve, confirming its excellent sensitivity.

1. FURRY AND REVERSE FURRY DESIGN COMBINATION
   The Bettersizer 2600 is a perfect combination of Fourier and inverse Fourier designs. This clever design allows, on the one hand, to detect extraneous light over a very wide angle range from 0.016° to 165°. On the other hand, in contrast to the inverse Fourier design, the particles do not have to be in the same plane – thus achieving simultaneous accurate measurement of small and large particles.
   • Features
     • Spherical detector array: Front, side and back detectors, in all 92 parts;
     • Very large Fourier lens;
     • Small footprint: Compact design to save space.
2. TILTED SAMPLE CELL
   • What is the total internal reflection reaction?
   • The reflection of light that occurs when it strikes an interface with a charging angle greater than the critical angle of the couple device.
   • How to reduce the effect of total internal reflection?
   • By tilting the sample cell, the angle of reception of the incident light increased to reduce the effect of total internal reflection.
   • Advantages of a tilted sample cell
     • Significantly reduces the effect of total internal reflection;
     • Wide measuring range due to large angle of reception of scattered light.
3. FOLDING BOX MEASUREMENT
   • According to Mie theory, laser diffraction measurements are difficult for the following sample types:
     • Samples with completely unknown complex flexibility;
     • Samples with heterogeneous chemical composition;
     • Samples with significantly different optical properties of the particles compared to the bulk material;
     • Samples with clearly strong optical scattering (low Abbe number).
   • Measuring the folding index is one of the best solutions. The Bettersizer 2600 can:
     • Determine flexibility for samples with unknown flexibility;
     • Measure samples with unknown properties;
     • To check known material data for a given wavelength of light;
     • Provide basic parameters for calculating particle size distribution in real time.
   • Advantages of moisture measurement:
     • More stable measurement results compared to dry measurements;
     • Repeatability testing capability;
     • Suitable for very fine particles and fragile samples.
   • Advantages of dry measurement:
     • Quick measurements;
     • No need for surface activator, low cost and environmentally friendly;
     • Suitable for samples that are easily dispersed and not fragile.
     • Less variability during the measurement process.
