WebIn addition to various purification and manipulation techniques, this section will also introduce you to spectroscopic techniques like nuclear magnetic resonance (NMR) spectroscopy, infrared (IR) spectroscopy, gas chromatography (GC), and ultraviolet-visible (UV-Vis) spectroscopy. Note: “CC” refers to the “Competent Chemist” modules. WebTLC is a sensitive technique - microgram (0.000001 g) quantities can be analyzed by TLC - and it takes little time for an analysis (about 5-10 minutes). TLC consists of three steps - spotting, development, and visualization. Photographs of each step are shown on the course website. First the sample to be analyzed is dissolved in a volatile (easily

WebTLC works by utilizing a solid stationary phase (most commonly silica gel) and a mobile liquid phase that travels up the TLC plate due to capillary action. The silica gel is very polar, so polar compounds will stick strongly to the stationary phase and not travel up the plate as far/quickly as less polar compound WebStains for Developing TLC Plates Once a TLC has been developed, it is frequently necessary to aid in the visualization of the components of a reaction mixture. ... lamps may be found as part of a standard organic chemistry research or teaching lab.
