  • Fast, reliable particle size measurement of fragile and cohesive dry powders.
  • Mastersizer know-how throughout, for results you can rely on.

How it works

The Mastersizer 3000 uses the technique of laser diffraction to measure the size of particles. It does this by measuring the intensity of light scattered as a laser beam passes through a dispersed particulate sample. This data is then analyzed to calculate the size of the particles that created the scattering pattern.

A typical system is made up of three main elements:

  • Optical bench - A dispersed sample passes though the measurement area of the optical bench, where a laser beam illuminates the particles. A series of detectors then accurately measure the intensity of light scattered by the particles within the sample for both red and blue light wavelengths and over a wide range of angles.
  • Sample dispersion units (accessories). Sample dispersion is controlled by a range of wet and dry dispersion units. These ensure the particles are delivered to the measurement area of the optical bench at the correct concentration and in a suitable, stable state of dispersion.
  • Instrument software. The Mastersizer 3000 software controls the system during the measurement process and analyzes the scattering data to calculate a particle size distribution. It also provides both instant feedback during method development and expert advice on the quality of the results.

Key applications

Pharmaceuticals

Particle size analysis is a critical material attribute (CMA) for all solid dosage forms and liquid suspensions of pharmaceuticals, used to assess Critical Quality Attributes (CQAs) of a drug product (such as bioavailability, product stability and content uniformity), in order to meet the desired Quality Target Product Profile (QTPP).

The particle size distribution of the active ingredient (API) in a drug is critical to its bioavailability.  The larger the surface area of a particle, the greater its solubility and dissolution rate, leading to increased bioavailability and a faster acting drug release.  The particle surface area is a function of particle size, so the smaller the particle size, the greater the dissolution rate and bioavailability of the drug (all other factors being equal).   Considering something like an indigestion liquid: the finer the particle size, the more cohesive the material is, the more prone it is to aggregation over time and the poorer its colloidal stability.  This in turn will affect the bioavailability of the drug, as the particle size distribution has now become larger over time, making the product less efficient.   The content uniformity of a tablet is also dependent on the particle size distribution of its constituents.  With a larger particle size, some unit doses may not meet potency specifications.  Furthermore, the excipient blend selection is also based on particle size.  The packing density of powders is dependent on their particle size distribution, with a mix of fine and coarse material leading to a higher packing density, and a lower permeability - leading to a slower disintegration of the tablet.

So, whether optimizing the particle size of the API and excipients during formulation development, checking the particle size of the raw materials from suppliers or conducting quality control at different stages of the manufacturing process, the measurement of particle size and particle size distribution is essential in pharmaceutical development and within the manufacture of pharmaceutical products.   

Inks, pigments and and coatings

Color, opacity, gloss, tinting strength, viscosity and sedimentation rate: all of these properties are affected by the particle size distribution of the pigments and extender pigments in the product.

Opacity, for example, is determined by the scattering efficiency of the pigments, which in turn is dependent on their particle size.  For titanium dioxide, which is a very efficient scatterer of light owing to its high refractive index, the optimum particle size for scattering white light is around 250 nm and thus laser diffraction is used to ensure the particle size is controlled between 200-350 nm.  This ensures it makes coatings appear bright white and effectively hides anything underneath.

Extender pigments are added to the formulation to reduce the amount of primary pigment used and to enhance the aesthetic and mechanical properties of the paint coating.  Reducing the particle size produces a smoother coating, increases the gloss and increases the opacity of the coating by controlling the spacing of the primary pigment particles.  Oversized particles (> 500nm) and larger agglomerates in poor dispersions will affect film properties like gloss, and will cause surface imperfections.

In the case of pigmented inks, which are used for ink-jet applications where durability and exposure to moisture are requirement, the presenence of oversized particles can lead to nozzle blockages, defect formation within printed film and inconsistent colour densities.

Catalysts

Specific Surface Area (SSA) is critical to heterogeneous catalyst activity.  The rate of reaction is dependent on the surface area of the solid catalyst, as this defines the contact area between the catalyst and the reactants.  Although traditionally determined using BET physisorption techniques, laser diffraction provides a fast and more efficient assessment of SSA, enabling quicker assessment and release of product.  

The SSA can be increased by milling the catalyst material, as this process reduces the particle size.  However, if the particle size is too fine, powder processing can become difficult due to its propensity for aggregation and it can also lead to loss of expensive catalysts through entrainment of fines within gas or liquid streams.  For example, in the case of FCC catalysts (used in the conversion of long-chain hydrocarbon fractions in crude oil to more valuable shorter chain hydrocarbons), if the particle size is too large it won’t flow up the column, but if it is too small, the catalyst will be lost. 

Laser diffraction can be used to assess the particle size distribution of a huge array of catalyst materials, ranging from Raney Nickel, Pt black, catalyst support mateirals, Ziegler-Natta catalysts, FCC catalysts, iron-based Fisher-Tropsch catalysts, supported metal and metal-alloy catalysts (e.g. Pd/C, Pd/CaCO3, Pd/BaSO4, Pd/Al2O3, Pd-Au/SiO2, Pd-Ag/SiO2, Ni-Cu/SiO2), Fe and doped Fe materials, etc.  In all cases, particle size analysis is essential for controlling powder processing and SSA, enabling optimisation of product properties and maintaining process efficiency.

Cement

Particles that are too fine (<2um diameter), lead to the cement curing exothermically, setting too fast and cracking.  However, large particles (>32um) may not fully hydrate during routine use, reducing the strength of the final product.  Typically optimum strength is achieved if 50-70% of the product lies between 2 and 32 um, depending on the intended grade of the final product.

To ensure the desired particle size range in the final grade product, a separator is placed after the finish mill.  Oversized particles are rejected and fed back into the mill for further milling, whilst those of the correct size are collected as final product.

The efficiency of the separator can be calculated by taking samples from the fresh feed, rejects and a separator is used to ensure particles of the desired particle size range are collected for the final grade product.
