の値をAmL及びBmLとする。The method for measuring sulfur is in accordance with the method for quantifying sulfur in sodium chondroitin sulfate in "Japanese Pharmacopoeia Standard 1997", but it is as follows. This product is dried, about 0.05 g of it is precisely weighed, and 20 mL of hydrogen peroxide test solution is used as an absorbent, and the test is carried out by the oxygen flask combustion method (Japanese Pharmacopoeia, General test method, 22). However, during the (2) combustion method of the test method, after leaving for 30 minutes with occasional shaking, the absorption liquid was transferred to another flask, and 15 mL of water was used instead of 15 mL of methanol,
The inner wall of the flask stopper (C), the platinum basket (B) and the Erlenmeyer flask (A) is washed, the washing liquid is combined with the absorbing liquid, and water is added to make exactly 50 mL to obtain a sample solution. A blank test solution is prepared in the same manner without using a sample. Accurately measure 10 mL of the sample solution, add exactly 5 mL of 0.01 mol / L barium chloride solution, and heat in a water bath for 25 minutes.
After cooling, the solution was neutralized by adding a 0.1 mol / L sodium hydroxide solution and titrated with a 0.01 mol / L disodium ethylenediaminetetraacetate solution, and the value was taken as amL (indicator:
Liquid universal BT 0.3 mL). However, the end point of the titration is when the red-purple color of the liquid changes to blue. Separately, accurately measure 10 mL of the sample solution, add 5 mL of water instead of 0.01 mol / L barium chloride, and perform the same operation to set the value as b mL. Perform the same operation for the blank test, and set the respective values as AmL and BmL.
