Crow, I believe ASD has a superior product for validating solid dosage meds, in other words, 90% of all prescription drugs.

I believe that CDEx realized their SafePill concept product (utilizing UVF) could not compete with NIR and as a result, SafePill morphed into Valimed which has been designed primarily for testing liquids. All the facts point to this conclusion.

UVF has advantages over NIR for testing liquids even though the market share for a liquid-only device is much smaller.

I believe that Valimed is no different than any other commercially available Fluorimeter. All have similar stand-off distances and integrataion times. All have their own custom spectral discrimination and LIMS integration software. Valimed is no different except that it has been customized for a highly niche market IMO. Others are customized too, I gave an example of another niche market fluorimeter, The Nanodrop (http:///www.nanodrop.com). Market niche: measuring samples that are only available in extremely samll amounts (e.g., DNA, RNA... etc.).

Does CDEx have superior tech? I don't think so. Loch/CDEx have advertised the detection of TRACE amounts of chemicals at huge stand-off distances for years but have we ever seen it? NO! It's a joke IMO. What is the distance of Valimed? Under an inch. How about the meth gun? Didn't we see a video of Foster sticking the nose of the gun into a huge pile of white powder? Ridiculous!

Show me TRACE DETECTION at even 10 meters and then maybe I'll change my mind. Right now it's all been BS and I think it's totally misleading and on the border of fraud!

"What I think they are doing is measuring the INTERFERENCE bands.. NOT the REFLECTED, so to speak, wavelengths."

NIR? I think you may be correct in a way. First, what doesn't reflect is either absorbed or transmitted. What is absorbed (or what is absent from the reflectance) tells a lot about the chemical make-up. Also how the morphology of the surface causes aberrations in the return signal (interferences, distortions, shifts) may also provide useful information (last part SWAG).

Is that what you meant?
