Question
Can LCW902 be used with LCK301 for determination of total Aluminium?
Summary
Sample preparation set LCW902 for measurement of total Aluminum is not mentioned in the manual of LCK301
Answer
The sample preparation kit LCW902 uses a hot acidic potassium peroxodisulfate digestion in glass vials.
The composition of glass contains Aluminum which will be partly released due to the strong digestion conditions.
This release of Aluminum out of the glass will lead to high bias results with LCK301 or other methods and therefore LCW902 is not recommended for Aluminum methods.
