5.4 Using an Existing Working Curve

5.4 Using an Existing Working Curve
In atomic absorption spectrometry, a working curve is prepared
for each measurement in principle since analytical sensitivity is
affected by such factors as atomizer conditions. However, the
existing working curve can be used as a software function.
For using the existing working curve, arrange the conditions for
minimizing the influence by sensitivity variations such as use of
the data just after measurement or combined use of the reslope
function.
(1) For using the data just after measurement, copy the
analytical method, referring to 5.3.
(2) For using the working curve in the saved data, open the
saved measurement result in the Data Process window and
click the [Copy Method] button. (Reference: 2.3.4
Opening a File)
(3) In response to the confirmation message, click the [OK]
button.

(4) Display changes to the Method window. Now, open the
[Standards Table] window and turn on the [Use Saved
Working Curve] check box. (Fig. 5-11).
