ICPMS定量限是这么写的“The limit of quantitation (QL) is estimated by calculating the standard deviation of NLT 10 replicate measurements of a blank
solution and multiplying by 10. When validating a procedure using the method of standard additions, the slope of standard applied to a solution of the test material is used. Other suitable approaches can be used (see<1225>).A measurement of a test solution prepared from a representative sample matrix spiked at the estimated QL concentratio must be performed to confirm accuracy. When validating a procedure using the method of standard additions, the validatio criterion applies to the final experimental result, not the spike recovery of the individual standard addition levels.
Validation criteria: The analytical procedure should be capable of determining the analyte precisely and accurately at a level equivalent to 50% of the specification”
想请教下有没有哪位老师知道是怎么做的吗?
