In an ISTD calibration, the calculation of the corrected amount ratio of a particular compound in an unknown sample occurs in several stages. These stages are described in the following sections. Witryna12 gru 2009 · But I recenly found this equation: area analyte/[analyte]=F(area istd/[istd]). Then for the standard addition method I was using this: [analyte initial]/[analyte+std]=area initial/(area analyte+std) But I don't know if the standard addition method can be used when I'm also using a istd. When I do the standard addition method, instead of using ... mary alyce rogers https://letmycookingtalk.com
