The performance of an analytical instrument is determined by parameters like repeatability, reproducibility, stability and accuracy. These parameters describe the instrument behavior in certain situations.
Repeatability is the probability that an analytical result remains the same for repeated measurements in a short period of time. If measured for a long period of time, this property is called stability. Reproducibility is the capability to repeatedly deliver the same result for the same measuring conditions but for different users. Finally, accuracy is the ability to obtain the correct result.
For this lab report, various measurements were performed to determine the repeatability and stability in dependence of different measurement parameters.
