Figure 100: Result of the dilution series measurement
In the example above, the measured value of the diluted sample is 14.5 mg/L. The dilution
factor of a 1+1 dilution is two. The expected value can be calculated as 29.0 mg/L. Based on
the measured value of the undiluted sample with 29.7 mg/L, this means an absolute
deviation of -0.6 mg/L. The relative deviation of -2.1% was therefore lower than the set
margin of 20%; the quality objective is given a "Passed" rating.
Various types of sample information can be entered using the icons located below the result
window. Press the
icon to view other available options.
Via the “Properties” command,
new sample information can be added below the measurement menu (see Section 5.2.1
).
The “Do not save” command prevents the measurement result from being stored in the
instrum
ent’s memory when the cuvette is removed or when the menu is exited
(Please note:
This function is only available in the "Open Mode")
.
Removing the cuvette or exiting the measurement menu by means of one of the other icons
in the task bar will end the measurement process and save the result in the IQC memory
(see Section 6.6.7 of the device.

Spike additions
Through the analysis of spike additions, interferences or problems with the sample can be
sought and detected.
Press the
icon to open a window for specifyfing the desired standard for the spike
addition measurement.
Select the entry “Standard” to open the list of the standards in the
device. Now the desired standard can be selected from this dynamic list or a new standard
can be defined via the
icon. After selecting a pre-defined standard, the rest of the
fields will be filled in automatically with the values for method, submethod, cuvette, increase
in concentration through spiking, and confidence interval. Entering the LOT for test kit and
standard via the text keypad and then confirming with
opens the measurement window.
In order to enter a user-defined standard, the
icon must be pressed
in the “Select
standard” dynamic list. A keypad will pop up for entering the name of the user-defined
standard. After the first measurement with the self-defined standard, the name entered here
will appear in the dynamic list for selection of the standard.
Tap the entry “Method” and then select the method for which you want to define the standard
from the “Select method” list that pops up. The submethod field can be used to select
submethods, if multiple submethods are available for a method. Use the alphanumeric
keypad to enter in the “Concentration increase” field the amount of analyte to be added to the
