Dilution and Quantification the Jelly Bean Experiment

Isotope Dilution and Quantification (the Jelly Bean Experiment) 

This demonstration is intended to show how quantification is achieved using isotope dilution principles in mass spectrometry (Fig. 14.5). It also shows the issue of error in clinical measurements, such as precision accuracy and the use of relative relationships of one compound to another. 

Materials required include a 100 mL beaker and jelly beans. The jelly beans should be of the smaller variety (about 5 mm in length). Other candies can be used provided they are uniform and are easily identifiable varieties. The experiment can be performed
