I understand completely that this device is not intended for resolution under 1%. BUT .. The current home pesticide test is real simple, but expensive. Here is a link
Now the basic chemistry is adding a solution to the substance and checking a color.. But your not really checking a color, your looking to see if there is a chemical reaction that changes color with concentrations. Now it takes (roughly depending on the test) 5ML of “stuff” and a few ML of “these stuff”, there is a better way.
If instead of scanning your veggies directly, put .005 letter’s on a test strip and wipe the veggie and then scan the strip…. Strips like this should be able to be made for fractions of a penny. You only need enough “Stuff” to get to 1% to have the SCiO get to fractions of fractions with a little help…
Am I on to something here ??
