YES Crow YES!!!
{i]"CDEX did publish explanatons of how Valimed works..an ISOLATED small sample of the med is zapped by a burst of UV radiation. The resulting flouresed radiation from the zapped sample is detected and compared to a stored pattern in the Valimed, called the signature."
If a G4 were to actually exist, the incident UV radiation must travel through the IV bag, tube, syringe (or whatever) and radiate the sample. As we known, these medical items are made from materials with UV resistant coatings and/or additives in their formulations so the burst of UV will have trouble getting through, but that's not the most difficult part.
The difficult part is the fluorescent return signal traveling back to the sensor. The intensity of the return signal is very, very small compared to the incident intensity which would make it extremely difficult to travel back through the material to the sensor.
But let's just suppose it could. The signal intensity would be attenuated by passing thru the material and each different type of material would have a different effect. The orientation of the medical item containing the med would also have an effect on intensity.
What this means is the CDEx would have to make up ALL NEW SIGNATURES, one for each different type of material and orientation of the medical item being sampled. Ya can't just toss the medical item "into the belly" like Pennstreet foolishly claims and expect consistent results every time.
Remember that Valimed uses the exact same cuvette and in the exact same orientation to create consistent signatures and test results. This would not be the case with the imaginary G4. The intensity of the return signal would be attenuated differently on a case per case basis and since the intensity is directly proportional to the strength of the med, concentration readings would be totally inconsistent.
They couldn't use an existing signature developed for Valimed with the G4. There would have to be hundreds of new signatures developed specifically for the imaginary G4 and I haven't heard of such a material event at this time.
As it stands right now, Valimed has a unique signature for each med at a particular concentration AND with a particular dilutent. If the concentration is changed a new signature is required; if the dilutent is changed a new signature is required.
Imagine all the signatures that WOULD be required with the IG4 (imaginary G4). Not only would it require a unique signature with different med concentrations and dilutents like Valimed, but it would also require unique signatures for each different IV bag, tube, syringe, vial... etc through which the sample is being tested.
And on top of that, a unique signature would be required for each differnt way the item to be sampled is "tossed into the belly " of the IG4- a different orientation, a different signature.
Highly unlikely that CDEX could pull that off in a few months, with no money and with outside vendors that have been stiffed.
HIGHLY UNLIKELY if not just plain hilarious to consider.
GUARANTEED.
