- Comment "A gross measure of the total carbohydrate material in a sample fraction can be obtained by measuring the total optical rotation of the fraction. With the differing amounts of sugars present, the direction and degree of rotation might be expected to change to some extent with fraction number. Within a fraction, if carbohydrate content is independent of the reaction stage, the direction of rotation would be expected to be the same for early, mid, and late reaction stages. The degree of rotation would then be proportional to the concentration, within experimental limits.Based on: The Institute of Paper Chemistry http://etd.gatech.edu/theses/available/ipstetd-42/albrecht_js.pdf [6.10.2009]"
