CAMAG Derivatizer

Automated spraying device for reagent transfer onto TLC/HPTLC plates

  • Unsurpassed homogeneous reagent distribution
  • Environmentally friendly and safe handling through a closed system
  • Reproducible and user-independent results
  • Low reagent consumption (2-4 mL)
  • Hood for 20 x 10 cm and/or 20 x 20 cm plates
    • Intuitive handling and easy cleaning

Product Description

Derivatization means another step in the process, consequently causing an increase in variance. Even if an experienced technician manually sprays a reagent, the relative standard deviation (RSD) of the measured values rises up to 12%. Using the Derivatizer, the RSD increases by less than 5%, thus providing very reproducible results, equal to those obtained with the Chromatogram Immersion Device, yet consuming considerably less reagent.

The following most common reagents have been tested and validated by the CAMAG laboratory for use with the Derivatizer:

  • Sulfuric acid reagent (10 % in methanol)
  • Anisaldehyde reagent
  • Natural product reagent
  • Polyethylene glycol solution
  • Iodine solution (0.5% in ethanol)
  • Dragendorff reagent
  • Fast blue salt B reagent
  • Ehrlich’s reagent
  • Phosphomolybdic acid reagent
  • Ninhydrin reagent Copper (II) sulfate reagent
  • Aniline-diphenylamine-phosphoric acid reagent
  • Vanillin reagent
  • Potassium hydroxide solution (5% in methanol)
  • Aqueous solutions (enzymatic solutions, etc.)

The Derivatizer is available for two different plate formats (20 x 20 cm and 20 x 10 cm).
