Also, many normal phase HPLC methods are a carryover from TLC methods in which water-saturated organic phases are commonly used - a typical example being Butanol-acetic acid-water ( 4:1:5, upper phase). The products of the reaction can be recovered by thin-layer chromatography on Whatman K6 plates in a solvent system of chloroform-acetone-methanol-acetic acid-water (4.5 2 1 1.3 0.5, v/v). At first put the solvent mixture into TLC chamber and then close the chamber. It may be suitable but it depends on your compounds. A solvent is a substance that can dissolve or dilute gases, liquids or solids without causing chemical reactions between the solute and the dissolving substance. one-phase solvent systems for paper chromatography. Tern Electric Vektron, Acceptable resolutions were achieved when it was applied for the separation of dipeptides including Leu-Tyr and Val-Tyr by using 1-butanol-acetic acid-water (4:1:5, V/V/V) solvent system. Sample Preparation and Loading; If the solid sample is used, it is dissolved in a suitable solvent. Thirty-nine dyes were subjected to thin layer chromatography to evaluate eight different solvent systems. However, solids can also dissolve other substances. The role of certain details important in the technique of TLC are layer thickness and homogeneity, degree of layer activation, solvent quality and aging of solvent mixtures, design of separation chamber and layer location, length of run of the solvent and distance from the immersion level to the origin of the chromatogram, technique of sample ap.
