Transfer of six thin-layer chromatography (TLC) Global Pharma Health Fund Minilab kit protocols for detecting fake or markedly substandard drugs in pharmaceutical products in the field to quantitative high-performance TLC (HPTLC)–densitometry methods was carried out using a model process published earlier. The developed and validated methods for tablets or capsules containing cefixime, cefuroxime axetil, cephalexin•H2O, ciprofloxacin HCl, levofloxacin, and metronidazole involved use of EMD Millipore Premium Purity silica gel 60 F254 plates, automated sample and standard solution application with a CAMAG Linomat 4, and automated densitometry with a CAMAG Scanner 3 for detection, identification, and quantification.
