HPTLC plates feature a smaller particle size (≤10 μm), and a narrower particle size distribution as compared to standard analytical TLC.  Higher packing densities and smoother surfaces, highlighted by greater luminosity in development, make HPTLC a powerful alternative to standard analytical TLC.

  • More resolving power per unit distance
  • Small sample amounts (0.01 – 0.1 µL)
  • Minimized solvent usage vs standard analytical TLC
  • Highly reproducible, focused bands for quantitative analysis
  • Ideal for instrument-supported applications
  • 5 to 10 times better detection sensitivity than standard analytical TLC

Comparison of HPTLC and TLC glass plates

HPTLC plates improve TLC performance with shorter migration times,
tighter elution bands, and increased sensitivity.

HPTLC Plate Type Description Features
Nano-Silica HD HPTLC Contains a specific pore volume of 0.75 ml/g and particle size of 2-10 µm. Narrow fractionation of silica particles allows sharper separations, can lead to shorter developing times, shorter migration distances, and increased detection sensitivity
C18-W HPTLC Normal Phase or Reversed-Phase separation modes with eluents from anhydrous solvents to mixtures with high concentrations of water. Separation of very non-polar and highly polar substances using aqueous solvent systems. Use to determine solvent system composition for downstream HPLC analysis. Provides additional selectivity’s as compared to Silica Gel plates. Very fast migration times.
C18-100 HPTLC Octadecyl-Modified Nano Silica Layers, Complete (100 %) octadecyl modification, carbon content 14%. Reversed-phase separation mode with eluents from anhydrous solvents to mixtures with up to 20% water. Use for Alkaloids, amino acids, barbiturates, polycyclic aromatic hydrocarbons (PAH), drugs, peptides, flavonoids, phenols, indole derivatives, steroids.
C18-50 HPTLC Octadecyl-Modified Nano Silica Layers; Partial (50%) octadecyl modification, carbon content 7.5% Reversed-phase separation mode with eluents from anhydrous solvents to mixtures up to 60% of water Use for· Alkaloids, amino acids, barbiturates, polycyclic aromatic hydrocarbons (PAH), drugs, peptides, flavonoids, phenols, indole derivatives, steroids. The 50% carbon load is less retentive than the C18-100.
Amino HPTLC Aminopropyl modification, carbon content 3.5% Moderately polar can be used in both normal and reversed-phase modes. Use to separate hydrophilic or charged samples, vitamins, sugars, steroids, purine derivatives, xanthine, phenols, nucleotides, and pesticides.
Cyano HPTLC Cyanopropyl modification, carbon content 5.5% Moderately polar can be used in both normal and reversed-phase modes. Use to separate hydrophilic or charged samples. Steroid hormones, phenols, preservatives.
Diol HPTLC Diol modification, carbon content 5.5% Moderately polar can be used in both normal and reversed-phase modes. Steroids, pesticides, and plant constituents, less sensitive than silica to the water environment.
