HEPARINIC ACIDS: DETERMINATION OF EQUIVALENT WEIGHTS AND SULFATE TO CARBOXYL RATIOS.
By means of an automatic titration apparatus, a polyelectrolyte of biological origin, heparin, from two animal sources, was found to have an average equivalent weight of 170.0, a sulfate content of 34.44 percent, and a sulfate to carboxyl ratio of 2.59.
