gc68907890a信噪比方法

1、AgilentGC6890/7890怎么算色谱峰的信噪比本文介绍AgilentGC6890/7890计算色谱峰的信噪比的方法。Agilent7890的计算方法与6890相同，故本文仅以6890为例说明。以下面这张色谱图为例:幕Instrum巳nt1(oFfline2):DataAnalysisFileGraphicsIntegrationCalibrationReportBatchViewAbortHelpData.AnalyisisShortECD1El.20111008S421.DIntegfation/Report耳引阪囤血1训乜1乂1坐l%lECD1B,(20-111008S421_D
