e. Does the test require the sample to be at a certain

temperature?

f. Was the pH of the sample in the correct range?

g. Is the pipette volume correct?

2. Check the used reagents by repeating the standard addition

procedure with freshly prepared reagents.

If none of these measures resolves the problem, please contact the

manufacturer or a sales representative.

6.3.1 Complete a standard addition

Carry out the standard addition in accordance with the

corresponding procedure.

There are two different methods:

Peak volume (Standard addition):

Defined volumes of a standard solution are added step by step to

an already analyzed sample. The sample is measured again after

each addition.

Sample volume:

A defined volume of a standard solution of known concentration is

added to the volume of sample specified in the procedure and the

sample is measured after each addition. In most cases three

different standard solutions are prepared and the procedure is

repeated for each of them.

Note: The units and chemical forms used for the sample are used for the

standard solutions. Be careful to ensure that to use the correct units for

subsequent entries.

Detection rate Conclusion

100%

The originally used reagents were defective.

Check the standard solution:

Repeat the standard addition procedure with a

freshly prepared standard solution.

Detection rate Conclusion

100%

The originally used

standard solution was

defective.
