4.3.47 Calibration by additionThis method calculates the concentration taking into account dilution volumes andhandling up to 4 calibration curves obtained from standard addition procedure ina blank solution. The signals can be a peak integration (Total, positive or negativeI or dI) or a peak coordinate in potential, differential potential, charge, current,differential current or A/D IN with selectable potential, time or current windows.Calibration by addition is a common protocol to obtain a set of calibration curvesfrom a unique standard solution. Adding to a blank up to four times in a row a givensmall volume of a standard solution of well known concentration, the operator willobtain a set of calibration curves. Interpolation provides the concentration in thesample, taking for granted that the recorded signal is linearly proportional to theconcentration and handling dilution volumes if needed.Consult the Help file, keyword index: Calibration by addition - Method editing.4.3.48 Calibration CV STThis Calibration Cyclic Voltammetry Standard Titration method creates a non linearcalibration curve. Adding to a blank up to 999 times in a row an adjustable volumeof a standard solution of well known concentration, the operator will obtain acalibration curve (signal versus concentration). The signals can be a peak position,peak height or peak integration (Total, positive or negative) with selectable potentialwindows and cycle number along a potentiostatic cyclic voltammetry. This methodis dedicated to Carrier (Wetter) measurement in plating processes such as in acidcopper baths.

Adding to a blank up to 999 times in a row anadjustable volume of the unknown sample, the operator will obtain a concentrationresult by interpolation with the calibration curve (signal versus concentration.
