  1. PLANT DRUG ANALYSIS BYOPTIMUM PERFORMANCELAMINAR CHROMATOGRAPHY Jacques POTHIER, Laboratory of Pharmacognosy Tours, France North Carolina University july 14 th 2003

  2. OPLC 50

  3. historique • École hongroise Erno TYIYAK Emil MINCOVICS • CCM rapide • En fait HPLC sur colonne plate

  4. OPLC principles:the « flat column » concept External pressure 50 bars Solvent in Way out Teflon sheet Micro groove Sorbent bed (silica) Metal cassette

  5. From OPLC 1 to OPLC 3 • In the begining OPLC was known as Overpressured layered chromatography • 1 chrompress 25 • 2 personal oplc • 3 to day OPLC is optimal performance laminar chromatography Forget the previous methods • The third generation is dependable, realiable and without surprises.

  6. What is OPLC ? • Planar and liquid chromatographic techniques • Hybrid technique between TLC and HPLC • Enabling high performance separation of single sample or of several samples in parallel • Laminar mobile phase • Gradient capabilities • Under pressure excluding vapor phase • Planar columns • Disposable, convenient providing laminar flow • Industry selection of phases and particle sizes (5µm, 11µm)

  7. OPLC 50

  8. From OPLC 1 to OPLC 3 • In the begining OPLC was known as Overpressured layered chromatography • 1 chrompress 25 • 2 personal oplc • 3 to day OPLC is optimal performance laminar chromatography Enhanced over previous methods. • The current generation is the latest OPLC.

  9. OPLC principles:the « flat column » concept External pressure 50 bars Solvent in Way out Teflon sheet Micro groove Sorbent bed (silica) Metal cassette

  10. OPLC/HPLC • In OPLC the column is always new. With HPLC...? • En oplc toujours possible de vérifier la migration • With OPLC, all eluents can be used, acidic and basic. • Peut servir pour transposition ccm hplc
