Why Chromatographic methods
Most effective method for determining type and concen. of mono and oligo involved in separating and identifying carbohydrates
How does electrophoretic methods work
Carbs undergo electrophoresis following derivatization to induce electrical charge
what happens to crabs with the electrophoretic methods
Carbs are separated according to size with smaller ones moving more quickly
Chemical Techniques
1) Gravimetric Methods
2) Colorimetric methods utilizing spectrophotometry
3) Titration
