Colorimetric Barcode for Detection of HME Precursors

Focus Area:
Colorimetric Barcode for Detection of HME Precursors

Detection and Identification


Develop a low-cost, colorimetric cassette for the detection and identification/differentiation of permanganates, peroxides, nitroaromatics, nitrate esters and nitramines, inorganic nitrates, ammonium nitrate, urea nitrate, chlorates, and perchlorates from one sample. A separate cassette will detect and identify aluminum, magnesium, and Iron(II).
