Advanced vision system central to Copley's validation service
According to Copley Scientific, the accuracy of cascade impactors used for characterising inhaled products depends heavily on the size of the nozzles on each stage of the instrument.
According to Copley Scientific, the accuracy of cascade impactors used for characterising inhaled products depends heavily on the size of the nozzles on each stage of the instrument.
Using a state-of-the-art vision inspection system, Copley has launched a new stage mensuration service. Stage mensuration is a cost-effective process for validating cascade impactors that involves measuring each nozzle to assess wear and corrosion. Regular stage mensuration is recommended in both the US and European Pharmacopoeias for performance validation.
The Mitutoyo QV404 automated vision inspection systemis also used in-house by major pharmaceutical companies and delivers unsurpassed reproducibility of 1 micron (to a 99% confidence interval). Copley says it is alone in Europe in offering a stage mensuration service based on this system.
The QV404 has auto-focus, auto-backlight illumination and dual measurement capabilities - edge detection and illuminated pixels. Use of this system combined with clearly defined and validated procedures for cleaning, calibration and measurement, gives the Copley stage mensuration service considerable integrity.
