Dynamic image analysis particle size analyzer QICPIC

for the pharmaceutical industryfor quality controlfor powders

Together with the powerful and fully-automated dry dispersion unit RODOS/L, the image analysis sensor QICPIC offers fast and repeatable analysis of particle size and particle shape for dry, fine to coarse-grained products from 1.8 µm to 4,000 µm. In addition, a fibre characterisation is also possible for fibre lengths significantly in excess of 4,000 µm. Even cohesive powders, intertwined fibres or agglomerating granulates are reliably dispersed and characterised. With the finely adjustable pressure ratios in RODOS, the energy input for dispersion is optimally adjusted to the product. No other dispersion method gets even close to this level of performance. The speed, reproducibility, comparability and the high statistical confidence with large sample volumes are particularly prominent. The dosing of the powder sample is performed by means of the precision vibratory feeder VIBRI/L, which guarantees optimum optical concentration of the sample in the measuring zone with a consistent, controlled product supply. The perfectly separated particles in the free aerosol jet are frozen in their movement with an exposure time of less than a nanosecond and recorded with a frequency of up to 500 frames per second. The subsequent evaluation returns all relevant size and shape characteristics, and the results can be presented both as a distribution and individually for each individual particle.
