Dynamic image analysis for dry powders and granules from 1.8 µm to 1,500 µm with automatic sample feeding
The powerful configuration comprising the image analysis sensor QICPIC, dry dispersion unit RODOS/L and sample handling system MULTISAMPLER offers fully-automated analyses of the particle size and particle shape of dry products ranging from 1.8 µm to 1,500 µm. All dispersion and measurement parameters are software-controlled and can be saved as retrievable measuring methods (Standard Operating Procedures (SOPs)).
For a high throughput of dry samples, MULTISAMPLER offers a fully-automated sample handling system. Up to 70 sample vials with a volume of 39 ml each are supplied from a rack to the system in batch mode. The samples are clearly identified with the aid of a data matrix code. Based on this information, the measuring method defined beforehand is selected for the sample and the dispersion and measurement settings are set up. Due to the vacuum in the RODOS injector, the sample is then aspirated from the vial with a sampler. The fluidised collective of particles is dispersed in the free jet where it is illuminated by the pulsed laser light and captured at a rate of up to 500 frames per second by the high-performance camera to be analysed.
Once the sample vials have been filled and been made available in the rack the system operates completely autonomously. By using two racks that feed into the system, it is possible to analyse up to 140 samples one after the other. In this way, even in unsupervised batch mode with different products and applications, it is possible to perform reliable, true-to-method and user-independent measurements for every single sample.
