The development of chromatography technology, with the increasing availability of easier-to-use mass spectrometers combined with gas chromatography (GC), the use of diode-array or programmable variable-wavelength ultraviolet absorption detectors in conjunction with high-performance liquid chromatography (HPLC), and the availability of scanners capable of . Chromatographic Purification and Analysis of a Mixture of Compounds The objective of this exercise is to separate a mixture of two compounds into two pure samples. This will be accomplished using flash chromatography in the next lab period, but before you can run the flash column, you need to discover the optimal solvent system by using.
