In quality control, research and development or even in environmental analysis, it is of great importance to count and detect the smallest particles in air, liquids or powders. At MedSolut.com, you can choose the particle measuring device that is right for you from a range of brand-name products. Our experts will be happy to support you in your selection with competent advice and excellent service.
The term particle measurement includes the detection of smallest particles in gases, liquids, powders or on surfaces. These include dust and other air pollutants, nanoparticles such as carbon black or pigments, but also viruses or bacteria. Depending on the particles to be detected and the medium to be analysed, different measuring methods can be used. These provide both qualitative and quantitative information.
The most important measurement principles can be distinguished as the following two:
Other measurement principles are based on the following methods:
MedSolut.com is currently focussing on particle measurement devices, which are primarily based on the first two methods of light scattering and optical image analysis. These two measurement principles are state of the art and cover a wide range of measurement possibilities.
Measurement according to the principle of light scattering With the light scattering principle, the measuring chamber is located between a laser light source and a detector. The sample is irradiated with laser light, the light is partially deflected by the particles and collected on the detector.
There, ring-shaped intensity patterns are created, each of which can be characteristically assigned to a particle size. Measurement according to the principle of optical image analysis With this measuring principle, dry samples as well as wet samples can be analysed reliably.
In both cases, the sample to be analysed is transported through a measuring chamber positioned between an LED light source on one side and a camera on the other. While the sample passes through the measuring chamber, high-resolution images are continuously recorded, which can then be evaluated by suitable analysis software.
At MedSolut.com you can purchase particle analysers from Fritsch, which are based on the principle of optical image analysis or light scattering. For emulsions, suspensions and pow ders the measuring principle of optical image analysis is particularly suitable. For liquid suspensions and emulsions with particularly small particles, light scattering is the optimal solution.
In optical image analysis, particles from 20 m to 20 mm are detected by the particle measuring instrument. In addition to the number of particles, the size and shape can also be determined. This is particularly useful in quality analysis, production control and research.
This method is also a fast alternative to sieve analysis. Light scattering measurements detect particle boundaries in the range of 0.01 m up to 3.8 mm. This is particularly relevant in quality control of production processes and in research and development.
Optical image analysis measurement systems are characterised by a high-quality camera that can produce a large number of images in a short time. A sophisticated analysis algorithm and an extensive database make it possible to present a meaningful result in less than five minutes.
The measuring systems based on light scattering are characterised by short measuring times, particularly high measuring accuracy and reliable reproducibility. With only one laser, a specially optimised measuring cell and one detector, no further optical elements are necessary - the system is practically maintenance-free.

In order to find the right instrument for your requirements, the following criteria are relevant as a first guide.
Since not all measuring principles are suitable for all samples, it is important to consider beforehand which substances are to be analysed. Powdery samples, suspensions and emulsions can be analysed using optical image analysis such as the FRITSCH Analysette 28 ImageSizer. Light scattering is more suitable for liquid samples with finely distributed particles.
Another question is which analytical limits are relevant. Particle size and number of particles are output by most particle sizers. If the particle shape is also relevant, this is currently only possible using optical methods.
Another criterion is the size of the particles to be analysed. Both measuring principles cover the range between 20 m and 2 mm. If smaller particles up to 0.01 m are to be detected, light scattering is advantageous. For larger particles up to 20 mm, optical image analysis is the best choice.
It is also important to consider the speed at which the measurement results must be available. This is important, for example, if online or inline analysis is being considered. Light scattering allows almost in-situ analysis. Optical image processing is somewhat slower due to the data transfer of images, here the results are available in a few minutes.
