text: An aqueous solution containing 2 g of glucose and 2 g of fructose per 100 g of solution contains 2/100=2% glucose on a wet basis, but 2/4=50% glucose on a dry basis.  If the solution had contained 2 g of glucose and 3 g of fructose, it would still have contained 2% glucose on a wet basis, but only 2/5=40% glucose on a dry basis.
  Frequently concentrations are calculated to a dry basis using the moisture (water) content :
  In the example above the glucose concentration is 2% as is and the moisture content is 96%.
