Calibration of 552.1 in triplicate--How is it done?

[Envirosun]

I have read the method and EPA 552.1 states that all calibration standards and blanks must be prepared and analyzed in triplicate. I can't see how to create a calibration table/plot in Chemstation/Enviroquant using three standards for the same concentration of each compound. Am I interpreting the literature incorrectly? Does anyone have a different take or a solution on this one?

Envirosun,

In Enviroquant when you re-calibrate (update levels) you can either replace or average responses for any given level. So, first you would clear all calibration values (to get rid of the old curve), then you would take your first cal point and replace and then you would take your second and third cal point and average.

Best regards.
