When the particle sizing results are different, it should be addressed as the following steps.

In particle sizing, we often encounter a situation: for the same sample, different instruments could produce different results. Some powder manufacturers and users tend to judge the quality of product...

Four main parameters are used to evaluate the performance of a particle size analyzer:(1) Sensitivity: refers to the change in test results when two samples with very small size difference (e.g., D50 ...

In addition to certificated reference materials, many instrument manufacturers also introduced the general reference materials (or working standard materials), which are used for the verification of i...

The calibration of a particle size analyzer can be performed using certificated reference material (CRM) or general reference material (RM).

The properties of particles include particle size, shape, surface structure and pore structure. The shape of the particles can impact on many properties of a powder sample.

Particle shape, also named as particle morphology, is currently characterized by measuring and calculating the projected shapes of the particles, including outline contour and roughness. All the metho...

A dispersant is a substance that significantly reduces the surface tension of the medium and hence improves the surface wetting or charged state of the particles.

Particle agglomeration refers to the aggregation of multiple individual particles under certain conditions. Agglomerated particles are characterized by low binding force and instability.

"Grounding" gives the shell of instrument and the common port terminal zero potential. It has two functions:(1) Improve the instrument stability by enhancing the ability of anti-interference;(2) Ensur...

The most commonly used liquid medium in particle sizing is water. Users could choose distilled water, purified water, deionized water, clean tap water, and well water. But no matter what kind of water...

The particle size measurement is a process of characterizing a small amount of sample to represent the whole batch of the product. Therefore, sampling is the first and also the most important step of ...

The commonly used liquid medium for particle sizing are water, anhydrous ethanol, and other organic solvents. For dry dispersion particle sizing, compressed air or compressed nitrogen are commonly used as gas medium.

Complete and detailed data: including frequency distribution data and histogram, cumulative distribution data and curve, original parameters, D50, D97 and other 10 typical values, simple distribution table, etc.

Bettersizer S3 Plus laser & imaging particle analysis system combined laser scattering and microscopic imaging for particle sizing and morphology analysis. In terms of particle sizing , the combin...

As a specialized manufacturer of laser particle size analyzer, Bettersize has made good progress in developing new technologies and obtained dozens of patents over the years. DLOS (dual lens optical s...

Laser particle size analyser is a professional laboratory instrument. There are many brands on the market with varying performance. The following suggestions may be helpful for users to choose instrum...

(1) Fast sampling speed: The sampling speed of the laser particle size analyzer reaches 2800 times/second, which can quickly collect the scattered signal, avoiding the signal loss and overlap, improvi...

(1) Certification and qualification: 'Bettersizer' has obtained CE and 21CFR Part11 certificates. The company has passed the ISO9001 quality system certification.(2) Original dual-lens optical system ...

'Bettersizer' series employed new technologies including DLOS (dual-lens optical system), automatic alignment system, SOP, results- conversion, result calibration, dry sampling and dispersion, automat...
