The CAMSIZER X2 is a powerful, extremely versatile particle size and shape analyzer with a wide measuring range that combines state-of-the-art camera technology with flexible dispersion options. Based on the principle of Dynamic Image Analysis (ISO 13322-2), the CAMSIZER X2 provides precise particle size and shape information of powders, granules and suspensions in a measuring range from 0.8 μm to 8 mm.

The CAMSIZER X2 produces a particle flow which is characterized by an optical system with high resolution. An ultrabright LED stroboscopic light sources and two high-resolution digital cameras achieve a frame rate of more than 300 images per second which are evaluated in real time by a powerful software. Thus, the CAMSIZER X2 captures the images of hundreds of thousands to several millions of particles with highest accuracy within only 1 to 3 minutes.

The CAMSIZER X2 provides a wide selection of particle information which allows for comprehensive and reliable characterization of the sample material. It is suitable for use in R&D as well as for routine tasks in quality control.

Particle Analyzer CAMSIZER X2 Reviews from our customers

"Been using this instrument for a while now for particle size analysis of our small molecule APIs. The performance, accuracy & reproducibility is excellent. The amazing part is its ability to work with very small sample size. Very happy with the instrument. "

Siddharth Shah

"The product is very easy to use; we get a lot more information from this system than we did from our previous analyzer. The staff diligently works with developing and meeting our internal needs and has been more than willing to provide the education and background necessary to get the biggest bang for our buck! We are very pleased with this instrument. "

Measurement Principle

Two cameras operate simultaneously during measurement: the BASIC camera (blue) analyzes the larger particles, the ZOOM camera (red) captures the small particles. This procedure ensures optimum measurement conditions for all particle sizes in a distribution. 

Measurement Principle

Elaborate Design for Maximum Flexibility

The CAMSIZER X2’s modular “X-Change” system offers three alternative dispersion options, permitting the selection of the optimum method for each sample type. The user may choose between wet dispersion with X-Flow or dry measurement either in free fall with X-Fall or in an air flow with X-Jet. The modules and cartridges are quickly and easily exchanged which makes working with the CAMSIZER X2 convenient and safe.

Dispersion by compressed air

Dispersion by compressed air

The X-Jet module disperses the sample via a Venturi nozzle and is suitable for the effective analysis of powders. The actual measurement of the particles takes place in the air stream. Dispersion pressure may be set between 0 kPa and 460 kPa. This ensures optimum analysis conditions for all sample types.

Dispersion in liquids

Dispersion in liquids

CAMSIZER X2 also offers the option to analyze particles in liquids with the X-Flow module. The suspension flows in a closed circle through a glass cell where the cameras record the particle images. The integrated ultrasonic unit further aids in the dispersion process. 

Dispersion by gravity

Dispersion by gravity

The X-Fall module is used for non-destructive measurement of sensitive samples in free fall to minimize particle breakage. The sample can be recovered after the analysis.

Air Pressure Dispersion with X-Jet

Many materials tend to agglomerate due to surface forces. The X-Jet module effectively disperses the particles in an air flow while passing through a Venturi nozzle. The dispersion pressure can be set as required for individual particles. For sensitive granules, for example, reduced pressure ensures non-destructive measurement. After passing the measurement field, the sample is automatically removed from the analyzer by a vacuum cleaner.

Air Pressure Dispersion with X-Jet

Wet Measurement with X-Flow

The wet module X-Flow analyzes suspensions in a size range from 0.8 μm to 1 mm. The sample moves within a closed loop from the dispersion bath to the flow cell where the camera system captures the particle images. X-Flow comes with an ultrasonic bath and strong centrifugal pump to ensure efficient dispersion. Suitable dispersion media are water, alcohol, and also nonpolar organic solvents.

Wet Measurement with X-Flow

Gravity Dispersion with X-Fall

Flowable, unagglomerated samples can be analyzed by using the X-Fall module. The measurement is non-destructive because the particles directly fall from a chute through the field of view. X-Fall is suitable for particle sizes up to 8 mm; the detection sensitivity for over-sized grains is extremely high. In contrast to dispersion by air pressure, the sample can be recovered after the measurement with X-Fall.

Gravity Dispersion with X-Fall

„Size“ is only defined unambiguously for spherical particles: the diameter is identical in all directions and orientations. For non-spherical particles, however, the dimensions can vary strongly, depending on the orientation and direction of measurement. Traditional sieve analysis, for example, separates particles on a wire mesh sieve stack with different aperture sizes into fractions.

The smallest possible sieve aperture that a particle can pass is defined by the particle’s smallest projection area. Hence, sieve analysis measures particles in a preferential orientation and provides information which is mostly based on the width of the particle. Particle size analysis with Laser Diffraction (LD) relates all measuring data to the diameter of a spherical particle model. Only dynamic image analysis offers different size definitions which can be ascertained simultaneously. This makes the results comparable to those obtained with other techniques.

The outstanding strength of DIA is the possibility to measure width and length of a particle and to provide a size distribution based on these parameters. The particle width (red curve) can easily be compared to sieve analysis results.

Hoppers and chutes

Hoppers and chutes

To achieve optimum feeding conditions, even for adhesive powders, we offer different chutes made of either stainless steel or aluminium hard-coat. 
The hoppers can be made of aluminium or stainless steel and can hold up to 0,6 l of sample. The hopper is adjustable in height which promotes uniform flow of the sample.

Dispersion nozzles

Dispersion nozzles

There are nozzle sets with different sizes of the orifice available for the X-Jet module. The standard aperture is 14 mm x 4 mm which is suitable for most samples to be analyzed. For very large or very small particles, other nozzle sizes can be advantageous.

Reference object

Reference object

By using a high precision reference object made by electron lithography, which simulates differently sized particles, the CAMSIZER can be recalibrated in a few seconds at any time. This means that the requirements of modern test agent monitoring are fulfilled.

Due to the unique two-camera principle, all measurement ranges can be analyzed in one measurement run, without any hardware adjustments.

Measurement range specifications for the diameter of compact particles
:

  • X-Fall (gravity dispersion)
    Standard: 10 µm to 3 mm with nozzle size 7mm x 14mm
    Alternative: 10 µm to 8 mm with nozzle size 14 mm x 14 mm

  • X-Jet (air pressure dispersion)
    Standard: 0.8 µm to 1.5 mm with 4 mm nozzle
    Alternative: 2 µm to 6 mm with 9 mm nozzle
    Alternative: 5 µm to 8 mm with 13.5 mm nozzle

  • X-Flow (wet dispersion)
    Standard: 0.8 µm to 1 mm2)

1) The lower limit for X-Fall depends on the sample properties (agglomeration).
For agglomerating particles the X-Jet or X-Flow module are recommended.

2) The upper size limit for X-Flow depends on the density of the sample material.
600 µm is a typical limit for materials with a density of up to 2.5 g/cm3.

The CAMSIZER X2 uses the principle of Dynamic Image Analysis (DIA). The unique principle is fairly simple: Dispersed particles pass in front of two bright, pulsed LED light sources. The shadows of the particles are captured with two digital cameras.

One camera is optimized to analyse the small particles with high resolution, the other camera for the detection of the big particles with a good statistic, that means large field of view. Each camera is illuminated by one LED with optimized brightness, pulse length and field of view. A user-friendly software analyzes the size and shape of each particle, and finally calculates the respective distribution curves in realtime.
