TLC General Information

    Principlec

      Thin Layer Chormatography has long been over 100 years on of the most useful of chormatography. In TLC, an aliqout of sample solution is spotted on a porous layer of adsorbent material.

TLC Plate Formats

    Layer Thickness

      TLC plates are 250µm thick for regular analytical TLC and between 500 and 2000µm for preparative TLC. HPTLC have a thinner layer of adsorbent between 150-200µm. All thickness designations are nominal. Actual thicknesses may very but are consistent from batch to batch.

VertiPate™ Soft-Layer

    S-G, Vertipate™ Soft-Layer TLC plate are the kind of most widly used when recovery of the separate compounds is desirable. No organic substances have been added to these products.
