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. D Attracted to the unique advantages of TLC? Now you can explore the world of thin-layer chromatography inexpensively. For only $60, your RSCo dealer can supply you with a starter kit of standard, reusable catalog items which will allow you to experiment with TLC before investing in more elaborate apparatus. Write us or call your dealer for details. D TLC's expanded uses are documented in a 30 page "Comprehensive Bibliography of Thin Layer Chromatography," available free from RSCo. Also available and free: RSCo Review, Vol. 4, No. 6, on TLC applications, techniques, and equipment. Research Specialties Company is the only domestic manufacturer of TLC apparatus.
