| Abstract: | A computer graphics analysis method combined a common ultraviolet spectrophotometer with computer program is given. The curve smoothing and fitting methods is discussed.The computer program is introduced. By use of the derivative spectrophotometry and computer program, the 0-2 degree derivative curve graph is drawn and measuring parameter is determinated about the ephedrine hydrochloride nasal drops. The content measuring is finished. The average recovery and the coefficients of variation are 100.92 % and 0.44 % respectively. |
