Measuring the same sample on the same instrument a week apart tests

  • A.the medium term stability of the instrument
  • B.the wavelength accuracy of the monochromator
  • C.how closely two separate instruments agree with each other
  • D.the colour vision of the operator concerned

Answer: A

Correct answer: the medium term stability of the instrument

Repeating the same measurement on the same instrument after an interval isolates drift: the sample and the method are unchanged, so any difference is the instrument moving over that period. Repeatability is measured over minutes and reproducibility between instruments; this is the term between them, and it governs how often recalibration is needed.
