Illicit drugs prepared with different method (powder or tablet) were detected using terahertz time-domain spectroscopy technique and spectralabsorption in terahertz regain was obtained.
The testing results of this method are basically consistent with that of the normal atomic absorption spectrometry using manganese sensitive line as analytical spectral line.
