Question
How often should be done the matrix corrections for the ISE online sensors?
Summary
ISE matrix correction
Answer
During the first month of operation a matrix correction should be performed every week. After ensuring that this interval is sufficient, it can be reduced to longer intervals.
The matrix correction should not exceed 1 month. After that period it is highly recommended to check the matrix correction.
A matrix correction should be performed whenever there is uncertainty about the quality of the readings and deviations to the lab results are detected.
