Testing for Pesticides

[Lolo]

Hi Everyone,

I am wondering if NIR Spectroscopy in its hacked form is sensitive enough to test for pesticide residue? 

The mental block I have is the following: If I scan an apple the residual agro chemicals would be in the fractions of a percent. How can we eliminate the noise of the apple itself and all its constituent parts.

Any advice or links are appreciated

Thanks  

Lolo

and http://publiclab.org/search/pesticides

show some of how to do this in raspberries! Hope that helps!
