"Sandia’s multispectral UV fluorescence lidar system was tested in July 1995 at the Nevada Test Site. Measurements were made on vapor plumes consisting of mixtures of benzene, m-xylene, p-xylene, and toluene ranging in concentration from 1 to 500 ppm. All measurements were made at a standoff distance of 0.5 km."

"The list below includes items that are used to make meth. When found clustered together, these items indicate that a pile of trash could be waste from a meth lab.

...

Cans of solvents such as Acetone, Benzene, Toluene, Methyl Ethyl Ketone or Xylene"


WOW, WHAT A COINCIDENCE. IN 1995 SANDIA HAD UV LIDAR THAT COULD DETECT METH SOLVENTS FROM 0.5 KILOMETERS 'BY COMPARING FLOURESCENCE SPECTRA AT EACH EXCITATION WAVELEGNTH COMPARED TO A DATABASE OF FLOURESCENCE SPECTRA FROM INDIVIDUAL SPECIES TO DETERMINE SPECIES CONCENTRATIONS' LOOKS LIKE A PRIOR ART REFERENCE THAT DESCRIBES A UV SPECTRAL METH DETECTOR
