Here's the latest:
'The VG4 system uses a patented detection process providing a real time (within seconds), quantitative (strength/concentration) as well as qualitative (identification of an unknown) analysis of high-risk single component compounded medications and treatment solutions.
In the near future, we expect the VG4 product line to address multi component compounded mixtures, such as total parenteral nutrition.
We expect to add oncology drugs to our formulary in 2013 as well. One of the most significant improvements with the VG4 is the capability of analyzing through most containers that are currently being used in pharmaceutical settings.'
I wonder if CDEx is referring to the expired patent (public domain) or the pending patent. I'm not aware of any current patent that covers this technology.
Again, as I correctly predicted earlier, I don't believe that anyone will be seeing the real-time measurement of multi component drug strengths anytime in the near future. Of course, pennstreet claims the company that was shipped a G4 well over a year ago is using it every day for exactly that purpose. Yeah right!
Also, CDEx now claims that the G4 can see through most containers which would explain why pennstreet says they draw a sample out of the bag or vial with a syringe as an option. WHY COMPROMISE STERILITY IF YOU DON'T HAVE TO?
The way I see it, it's an option if drawing a sample into a syringe is the only way to identify the drug!
