4. TLC is still useful in the lab but is being replaced by automated chromatographic methods. For example, TLC, FPLC, and HPLC are now automated processes, and computers can control various parameters, such as flow rate, blends of solvent mixtures, etc. Can you think of how the ability to manipulate the parameters of these automated chromatographic methods (sample size, column plate length, flow rate, solvent gradients, etc.) might accentuate or improve an investigator's ability to separate amino acids or other biomolecules?
