将系统适用性溶液、供试品溶液室温下放置后测定，考察溶液稳定性，结果见表

After the system suitability solution was allowed to stand at room temperature for the determination of the test solution, the solution stability investigated, the results shown in Table 5 and 6. <br>Table 5 solution stability test results in Table <br>Table 6 sample solution injections continuously stability test results in Table <br>organic impurities system suitability solution at room temperature sertraline placed 7.5h, Raymond HYDROCHLORIDE rounded area RSD of 6.7%, Sertraline Related compound A 4.0% RSD of peak area, the system suitability solution at room temperature within 7.5h stable; <br>for 4h to stand at room temperature for the sample solution, the detection result is unstable, the test solution should be Pro with the new feature.

The system applicability solution, the test solution at room temperature after placement determination, to investigate the stability of the solution, the results are shown in Table 5, 6.<br>Table 5 Solution Stability Test Results Table<br>Table 6 Table of continuous sample stability test results for test solution<br>After the applicable solution of the organic impurity system of hydrochloric acid shequlin was placed at room temperature of 7.5h, the area of the hydrochloric acid shequlin peak was RSD of 6.7%, the AREA of Sertraline Related compound A peak WAS 4.0%, and the system applicable solution was stable within 7.5h at room temperature;<br>After placing 4h at room temperature, the test results are unstable, and the test solution should be newly fitted.

Put the system suitability solution and test solution at room temperature for determination, and inspect the stability of the solution. See Table 5 and table 6 for the results.<br>Table 5 results of solution stability test<br>Table 6 stability test results of continuous sample injection of test solution<br>The RSD of sertraline related compound A and sertraline related compound a were 6.7% and 4.0% respectively after 7.5h at room temperature;<br>After the test solution is placed at room temperature for 4h, the test results are not stable, and the test solution should be prepared temporarily.<br>
