chemical analysis

• chromatography: a technique for the separation of a mixture by passing it in solution or suspension through a medium in which the components move at different rates.
• paper chromatography: a form of chromatography where paper is used as the stationary phase, with solvent being drawn up by capillary action
• gas liquid chromatography (GLC): a form of chromatography that uses a gas as the mobile phase and a solid material coated onto an inert support as the stationary phase
• thin layer chromatography (TLC): a form of chromatography using a thin layer of silica gel on a glass plate as the stationary phase
• thin layer chromatography (TLC): a form of chromatography using thin layers of silica gel on glass plates to separate mixtures
• high performance liquid chromatography (HPLC): a more sophisticated version of GLC using high pressure to force the sample through the column faster than normal GC
• gas-liquid chromatography (GLC): a method of separating volatile substances by passing them over an inert solid support coated with a liquid that has a high affinity for one component of the sample
• high performance liquid chromatography (HPLC): a more sophisticated version of GLC, using high pressure to force the sample through the column faster than normal GC
• high performance liquid chromatography (HPLC): a more sophisticated version of TLC, using a pumped stream of liquid instead of capillary action
• thin layer chromatography (TLC): similar to paper chromatography but instead of paper, a thin layer of silica gel is spread on a glass plate
• mass spectroscopy: a method of identifying substances based on their mass-to-charge ratio
• ion exchange chromatography: a type of chromatography based on ionic attraction between charged particles and oppositely charged resins
• atomic absorption spectrophotometry: a method of determining the concentration of elements in a substance by measuring how much light they absorb when heated
• high performance liquid chromatography (HPLC): a more sophisticated version of TLC, using high pressure pumps to force liquids through narrow columns packed with small particles of silica gel
• atomic absorption spectrophotometer: a device used to measure the concentration of metal ions in a sample
