THIN LAYER CHROMATOGRAPHY fast, inexpensive, versatile technique TLC (Thin Layer Chromatography) combines the analytical capabilities of column adsorption chromatography and the convenience, simplicity, and low cost of paper chromatography. DThe ability to resolve quantities of sample as small as a few nanograms or as large as 100 milligrams on one plate makes TLC a perfect complement to gas chromatography, infrared, and other analytical methods. DTLC is rapid and easy to use. Resolutions of complex mixtures often take less than 20 minutes. No great skill is required to form layers of adsorbents or to process plates.
