问题用HPLC法测得某药保留时间为12.54min，半高峰宽0.6min，色谱柱的理论板数为

选项 A:116 B:484 C:2408 D:2904 E:2420

答案 E

解析色谱柱的理论板数计算式为：n=5.54(tR/W1/2)2,n=5.54(12.54/0.6)2=2420。

错误啦！

消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
