Chromatography
Chromatography (from Greek ?????:chroma, colour and ???????:"graphein" to write) is the collective term for a family of laboratory techniques for the separation of mixtures. It involves passing a mixture dissolved in a "mobile phase" through a stationary phase, which separates the analyte to be measured from other molecules in the mixture and allows it to be isolated. Chromatography may be preparative or analytical.

Gas Chromatography | Post?Lab Questions
The analysis is performed using gas chromatography. Introduction. The term chromatography applies to the separation of chemical constituents in a sample so they can be either detected or utilized individually. Gas chromatography (GC) is a method of separating “volatile” compounds (those with a high?vapor pressure or a relatively low boiling point) so that they may be ... Component 3. Post?Lab Questions: 1. Two different common methods of separating compounds using a column depend on boiling point and on.

Laboratory Techniques
Once the data is in hand, calculations are done with the numbers obtained. How good the calculations are depends on a number of factors: (1) how careful you are in taking the measurements (laboratory techniques), (2) how good your measuring device is in getting a true measure (accuracy), and (3) how reproducible the measurement is (precision).
Thin Layer Chromatography Characterization of the
Only silicon-coated, plastic chromatographic plates were used throughout the experiment. Ground Excedrin tablets were dissolved in dichloromethane. Ethyl acetate was used to conduct thin layer chromatography on the dissolved components of the ground-Excedrin solution. In the same manner, a thin layer chromatogram was taken of ground Anacin-tablet material.

How fast each pigment travels depends on the size of the pigment molecule and on how strongly the pigment is attracted to the paper. Since the water carries the different pigments at different rates, the black ink separates to reveal the colors that were mixed to make it.
