Gas Chromatography
allows a mixture of compounds to be separated, by their weight
- 1. sample dissolved in solvent and then injected into an end of the column
- 2. unreactive gas (nitrogen) carries sample through column
- 3. dif. substances travel through column at different speeds, and therefore become separated
- 4. separated substances leave the column, one after another. as they leave, they are detected by detector
