Crow,
Some chemicals fluoresce, some don't, some fluoresce strongly like most aromatic compounds such as benzene, m-xylene, p-xylene, toluene and methamphetamine all containing the phenyl group.
Our message board stock promoters have been hyping how fast the meth gun is as seen in the mock-up promotional video.
Here's some observations:
1. The meth gun is being promoted as having the competitive advantage of detecting trace quantities of meth, that appears to me to be the market niche. The promotional video shows several large piles of white powder (bulk) being tested. Please show us how fast trace detection works.
2. The gun is under two inches away from the bulk piles. Please show us how fast the gun works with trace detection from at least 18 inches away (like the video of the cop pointing the gun into the car from the open driver's side window). Better yet, show us trace detection at 34 inches in about 5-12 seconds as stated by RB poster "wpoteet".
3. The meth gun is based on the same core technology that could not perform to Army satisfaction to continue further development. Please show us that the meth gun has a scan distance, scan footprint and shoot time that is practicle for it's intented use- unlike the Army conclusion.
4. If the meth gun will not perform as well for other chemicals as it does for meth please list the chemicals which it will effectively detect that may likely be found in a meth lab environment, for example, meth lab precursor chemicals.
5. I find it highly misleading to read posts from message board stock promoters claiming the meth gun has a shoot time of 3-6 seconds just because they seen a promotional video testing an unknown bulk pile of white powder at under two inches. A cop doesn't need a meth gun to arrest a suspect for probable cause if such quantites of white powder are discovered IMO.
6. The longer the stand-off distance the longer the shoot time.
7. The smaller the concentration, the longer the shoot time.
