Cone angle / Plume Geometry Measurement
For cone angle and plume geometry analysis of an aerosol or spray a laser lightsheet slices through the plume and a high speed movie is taken. Images from the movie are combined and the cone angle and plume geometry measured with Envision:Patternate software. The real power of automated analysis is that it removes the plume geometry discrimination from the user, and automates the whole process.
Spray Pattern / Ellipticity Measurement
For ellipticity / pattern characterization the laser lightsheet is repositioned and again a high speed movie is taken.
Images of the aerosol plume are combined and an ellipse is fitted to the resulting ensemble providing a measurement of the spray pattern. The maximum and minimum chords across the ellipse are measured and can be automatically reported.
Flexible when you need it
Envision Patternate software is designed to provide the maximum flexibility when you need to design your experimental algorithm. The QC module then allows the algorithm to be turned into a 21 CFR pt. 11 compliant method, complete with a full audit trail and multi-level user access.
A Powerful Development Tool
In addition to providing quantitative data, the Envision systems can provide images of the break-up and droplet formation process. This can provide an extremely valuable insight into the process and aid product develpoment and troubleshooting.
