basic stamp with fiberoptics
Archiver

Ladies, Gentlemen,
I am presently working on the blend uniformity grad project. I am
looking at a very compact device that would allow the determination of
powder homogeneity. I got the basic stamp in class version but it
seems there are quite a few components which are not useful to my
application. I have been proposed to use the BS2-IC version which is
suppose to be the smallest. I don't know if I can have all the needed
components.
This device would be installed (fixed) inside or outside the
solid-solid (pharmaceutical powders)blender and data acquisition would
have to be taken through time. Then, data would have to be downloaded
in a computer and analyzed. A proper calibration curve would allow the
analysis.
I was thinking of using fiberoptics attached to the stamp and I was
wondering if anybody has experience in that sort of application to
help me determine if it's possible and what would be the best
configuration. I probably would be using three sources of light
fiberoptics with three other ones as detectors (probably relectance
sensor - photodiode whith something to absorb blue light since the
first material I will be using is in the visible blue spectrum of
about 620 micro-meters) settled at different spots in the blender.The
data acquisition could be voltage that could then be transfered in
pourcentage of each components. The best situation would be to allow a
chemical imaging of the whole blender through time. Maybe we are not
there yet...
The project is still at the first stage. If you can bring any help on
defining a proper method to assess blend uniformity, it would be
greatly appreciated.
Thank you very much for your collaboration.
Have a great day.
