Scientific Adsorbents Inc.'s technology and experience has resulted in one of the broadest TLC - HPTLC - "S" HPTLC programs in the world. Our TLC - HPTLC program is one of the most complete. Included in the program are Silica Gels, Aluminas, Cellulose and PEI Cellulose. In addition, we supply these materials in a broad variety of layers and plate types.

Product Codes

Layer Code/Type Layer Description Feature/Benefits
Analytical TLC
HLO Hard - Layer - Organic Binder HLO the most abrasion resistant high resolution TLC product available in our program. Write directly on the plate. Outstanding detectability, sensitivity; minimal breakage.
  • High Resolution
  • Standard of the Industry
  • Durable Reflective Surface
G Soft Layer "G". A soft layer with inorganic "G" binder (CaSo4); ideal for use with aggressive detection reagents. Relatively easy to scrape and elute. These plates are fragile; use HLO plates if stability is a factor.
  • Ideal for Pre TLC, mgms to gms
  • Withstands Aggressive Sprays, Reagents
  • Classical Formulation
Alumina A, B, N Select the pH most appropriate to your separation, A=Acid, B=Basic, N=Neutral. Alumina is stable at pH 4 - 14 and can be used to separate most compounds, especially basic.
  • Ideal for the separation of basic compounds
  • Standardized Particle for TLC, Prep TLC
  • Stable Reproducible Layer
PEI - Cellulose Ideal Anion ion-exchanger for many life science applications e.g. nucleic acid compositions. Keep refrigerated at 4o Celsius to avoid discoloration.
  • Long Chain Anion Exchanger
  • Bio-Life Science Applications
  • Stable Reproducible Layer
Cellulose Available as microcrystalline and Avicel layers for the separation of polar compounds via liquid - liquid partition chromatography.
  • Liquid-Liquid Partition Separation Mechanism
  • Ideal for Polar Analytes
  • Available as Crystalline or Native Fibers

HPTLC and "S" - HPTLC Advanced Layers

HPTLC A 5 micron particle, 200 micron thick layer, suitable for very difficult separations. Spots of 1 -2 mm will optimize separations. Three to five times the resolving power of TLC. Fast development time.
  • Obtain 3-5,000 Theoretical Plates/5 cm
  • Ideal for the Most Difficult Separations
  • Resolution similar to HPLC
'S' HPTLC The ultimate in separating power; 3-10 times the resolving power of TLC. Technology and separation dependent on a 3 micron particle; 100 micron layer. Separate nanogram - picogram quantities. Spots of 1 - 2 mm will optimize separations.
  • Smallest TLC Particle (micron), Highest Resolution
  • Fast Analyses
  • Thin, Highly Reflective Surface

Prep TLC

Prep TLC Select 500, 1000, and 2000 micron layers according to the amount of material to be separated
  • Readily isolate mgm-gms
  • Standardized Particle for Prep TLC Prep LC
  • Wide Variety of Prep TLC Layers

Selected Backings

Glass Backing Use glass for optimum separation and with aggressive mobile phases. Inert backing will not react with selected detection sprays. Easy to handle. Best resolution.
  • Resistant to virtually all sprays, eluants
  • Rigid support for optimum resolution
  • Available in micro-macro sizes
Plastic and Aluminum Backing Unbreakable and easy to handle. Cut into any size. Easy to isolate one spot for subsequent elution/detection. Can be easily included (attached) to lab reports.

Aluminum backing is safe for use at higher temperatures and environments where strong solvents are used.

  • Cut into virtually any size
  • Readily isolate any spot and subsequent detection
  • Ideal for documentation

Specialty TLC

Scored Plates A single pre-scored plate provides the economy of selecting plate dimensions. Virtually any size plate is available in a single product.
  • Numerous sizes on "one" plate
  • Flexible unit, product matches need
  • Economical, use only as needed
