      Development and validation of a high-performance thin-layer chromatographic method for determination of ofloxacin residues on pharmaceutical equipment surfaces
      Irena VOVK*, B. SIMONOVSKA (*National Institute of Chemistry, Laboratory for Food Chemistry, Hajdrihova 19, SI-1000 Ljubljana, Slovenia, and EN-FIST Centre of Excellence, Dunajska cesta 156, SI-1000 Ljubljana, Slovenia; irena.vovk@ki.si)

      J. AOAC Int. 94, 735-742 (2011). HPTLC and TLC of ofloxacin on silica gel with ethanol - conc. ammonia 4:1 in a horizontal chamber. Quantitative determination by fluorescence measurement at 313 nm. Simulated samples at a residue level of 1 mg/m² were prepared by spreading the calculated amount of ofloxacin solution on 1, 5, and 10 dm² stainless steel surfaces. The hRf of ofloxacin was 56. The mean recovery (n = 6) was 88.6-95.3 % with a CV of 3.8-4.9 %. The LOD was 0.6 ng/zone and the LOQ was 2 ng/zone, but it was shown that these can be lowered by immersion of the developed plate into a solution of liquid paraffin - n-hexane 1:2 to approximately 0.3 and 0.9 ng/zone. The repeatability (system precision) was 4.2 % for 2 ng, and 3.7 % for 20 ng. The recovery was between 88.6-95.3 %.
