Liquid chromatographic/(LC) analysis is an effective instrument for pharmaceutical analysisand pharmaceutical science. Various methods have been utilized in attempts to optimize LC analytical conditions. ln order to obtain a high degree of separation, the optimum conditions were determined by the use of dynamic S/N ratio as an index for the evaluation of the separation process. An L18 orthogonal array was used in this experiment. lt was demonstrated that S/N ratio was an appropriate scale to indicate the separation of some peaks in a LC. Also, the appropriate types of S/N ratio to show the degree of separation in a LC was discussed.

Generally, a liquid chromatography (LC) is widely used in the field of a chemical and a pharmaceutical analysis. On account of many advances of a modern technique of the instrumental analysis and the appearance of high resolution column, a chemical analysis and a quantitative analysis are done more accurately than before. However, it seems that the determination of the analytical condition is mostly performed empirically. ln development of a new drug research, LC is an indispensable tool for the analysis of the chemical components, and so it is important to get the analytical conditions which is able to performed high degree of the separation. This paper describes that the parameter design was conductedto optimize the analytical condition of a LC. The experiments were conducted on the L₁₈ orthogonal array. Evaluation was done by the S/N ratio and sensitivity in comparison withthe current condition. The optimum condition was determined from the control factor levels which gave the large values of a S/N ratio and sensitivity S. As a result, an improvement was estimated as 3.32db in a S/N ratio. lt seems that this method can be widely applicableto the determination of the analytical conditions of a LC.
