Document Summary
In order to find and compare the amounts of caffeine in different sodas, a sample of soda was taken and the caffeine in the sample was extracted into dichloromethane, filtered, isolated and purified.

The amounts of caffeine in soda and other food products varies so it is important to be informed about the amounts of caffeine one consumes so that the maximum daily intake of caffeine is not surpassed. Some negative effects of passing the recommended daily intake of caffeine include insomnia, headaches and anxiety. Health canada has published that a 2. 5mg/kg daily intake should not be exceeded if negative side effects of caffeine are to be avoided. Other methods for caffeine purification and measurement include gas chromatography and a nitrogen- phosphorus detection.
