Abstract:
This article reports basic analytical data for screening and detection of the hypnotics zolpidem (CAS 82626-48-0) and zopiclone (CAS 43200-80-2) by using corrected hR-values, GC (gas chromatography) retention indices, UV solvent spectra and remission spectra. Beside this a HPTLC (high-performance thin-layer chromatography)-procedure for quantification is described.
