Science Buddies: "Ask an Expert"

Hello again! I was wondering if someone could answer this question for me. I am doing the project about measuring sugar contents with laser pointers, but I was wondering if someone knew of other methods of finding sugar content. I am writing a research paper and I need to know. Thanks!

Hi greensquirrel,

A variety of techniques can be used to measure the concentration of solutes in a liquid. I suggest you do some background research on spectrophotometry, liquid chromatography, and mass spectrometry for your paper.
