ALB, Alumina B TLC plates are basic aluminium oxide. TLC plates are recommended for terpenes, alkaloids, steroids, aliphatic and aromatic compounds. Activated plates at 120°C for 10min before use for improved separations.

     ALN-G, Alumina N Inorganic Hard-layer TLC plates are neutral aluminium oxide containing calcium sulfate hemihydrate as a binder. These TLC plates are recommended for terpenes, alkaloids, steroids, aliphatic and aromatic compounds. Activated plates at 120°C for 10min before use for improved separations.

     MC, Microcrystalline Cellulose TLC plates are coated with microcrystalline cellulose (Avicel^®). The adsorbent consists of regenerated alpha cellulose particles of nearly spherical shape and 50?m particle size. Layer are binder free and abrasion resistant. Compounds separated on this cellulose tend to form more compact spots than on fibrous cellulose layers. Recommended for carboxilic acids, lower alcohols, urea and purine derivatives.

     DC, DEAE Cellulose TLC plates are coated with Diethylaminoethyl (DEAE) Cellulose. They are positive charges at neutral and acidic pH for separation of negatively charged molecules by ion exchange chromatography. Hydrophilic nature of the cellulose substrate makes it well suited to ion exchange separations of delicate biomolecules such as protiens ,hormones and enzymes. Plates are available with mixed layers containing both DEAE Cellulose and unmodified cellulose. Mixed-layer plates have lower ion exchange capacity and may be expected to provide higher chromatographic mobility for negatively charged molecules.

     MDC, Mixed Cellulose TLC plates are mixed layers containing both DEAE Cellulose and unmodified cellulose, 7.5:1. Mixed-layer plates have lower ion exchange capacity and may be expected to provide higher chromatographic mobility for negatively charged molecules
