DCI PSA system is a static Image Analysis Particle Size Analyzer capable of measuring in one pass, a and very wide range of particles ranging from 10.0 μm to 10 000 μm (10.0 mm). The instrument principle is to scan a full sample of up to 80 x 80 mm and create a single seamless image from the 500 independent images acquired. Measuring a single large mosaic made of several images eliminates edge errors and assures accurate measurement of very large particles that could occupy several image Fields. Thus, particles or fibers of 10 000 microns or even larger may be quantified at the same time as tiny of 10 μm particles.
DCI PSA instrument is mainly aimed at the “Contaminants assessment” market of 47.0 mm membrane filters applications (Paper or Synthetic) as per International Standards such as ISO 16232, ISO 4406, VDA19 and others. Typical analysis time for a 47 mm Filter is 80 seconds. However, the instrument can be used for any other reflected light Particle Sizing application of 10.0 μm and above.

Ease of use:

The DCI PSA design was focused on theease of use. Therefore, it is much simpler to operate than a traditionnal microscope or stereoscope based system.

Metallic particles detection:

The DCI PSA is able to detect metallic particles from non-metallic ones through advanced image analysis functions.

Sort measured objects from morphological and size characteristics:

Easily review your data based on the characteristics you chose to measure. Ensuring a quick and easy data validation.

Mosaic analysis

The entirety of the filter is analyzed at the same time. No need to worry about measurement problems caused by image frame edges.

Measure everything in a single analysis

Measuring the whole filter in a single analysis allows to measure all sizes of particles on the filter.
