TY - JOUR U1 - Zeitschriftenartikel, wissenschaftlich - nicht begutachtet (unreviewed) A1 - Spangenberg, Bernd A1 - Weyandt-Spangenberg, Marion T1 - A Validated Quantification of Methadone in Liquids Using Thin-Layer Chromatography and a Flatbed Scanner T2 - JPC : Journal of Planar Chromatography - Modern TLC N2 - We present a videodensitometric quantification method for methadone in syrup, separated by thin-layer chromatography (TLC). The quantification is based on a derivation reaction with Dragendorf reagent. Measurements were carried out using a 16-bit flatbed scanner. The range of linearity covers two magnitudes of power using the Kubelka-Munk expression for data transformation. The separation method is inexpensive, fast, and reliable.
