Use of chromatography and different types - Chromatography is useful because it enables the separation, isolation, purification, and identification of components of extremely complex mixtures - There are different chromatography techniques: - Paper chromatography - Column chromatography - Thin layer chromatography - The results of chromatographic analysis are called chromatograms - The number of spots or peaks correspond to the number of components in the sample - If only one spot...

What were food color additives initially used for?To make food more visually appealing to the consumer and mask poor quality. Why were almost all of the original food color additives phased out?Most were not safe for consumption and were being added to foods with no health testing. What could have been done to determine whether a color additive was harmful before it was used in the food industry?They could have used chromatography to determine the purity of each additive. Of the origi...
