Question

Select the entry with the correct answers to the following questions:

a) For the absence of a matrix effect, use external calibration
b) For the absence of a matrix effect, use internal calibration
c) Random error is minimized by selecting the appropriate calibration method
d) Systematic error is minimized by selecting the appropriate calibration method

Answer 1

The correct answer is d) Systematic error is minimized by selecting the appropriate calibration method.

Step-by-step explanation:

The correct answer is d) Systematic error is minimized by selecting the appropriate calibration method.

1. For the absence of a matrix effect, external calibration is used, not internal calibration. Internal calibration is used to correct for instrument variation, not matrix effects.
2. Selecting the appropriate calibration method helps minimize random error, not systematic error. Random error is reduced through multiple measurements and statistical analysis.
3. Systematic error, on the other hand, is minimized by selecting the appropriate calibration method. Systematic errors are constant and can be corrected through calibration.

Therefore, the correct answer to the question is d) Systematic error is minimized by selecting the appropriate calibration method.
