In the paper two ways of using thin-layer chromatographic data for mobile phase optimization in column chromatography have been presented. The first method is connected with experimental correlations between thin-layer and column retention parameters. This moderately simple method needs to determine the...
What are the advantages of each type? What advantages does using iodine have over using UV to view TLC plates (and vice versa)? Describe the similarities and differences between the four nitrogen bases of DNA. What are the advantages and disadvantages of...
What are the advantages and disadvantages of flame ionization detector (FID) and thermal conductivity detector (TCD)? Explain the difference between TLC and column chromatography, and differences in their uses. What is the purpose of sunlight in the TLC experiment? How did...

This working technique has, apart from technical perfection, as is now available in the "U-Chamber," the minimum of prerequisites. The chapter discusses the working technique in circular chromatography. Two possibilities are available: (1) The TLC plate is placed coated side down and the ...
