Summary

This study introduces FUMI theory, a novel method to determine measurement precision from a single experiment. This approach offers the statistical reliability of 50 repetitive experiments without needing multiple trials.

Area of Science:

Analytical Chemistry
Statistics

Context:

Measurement precision, expressed as standard deviation (SD) or relative standard deviation (RSD), is crucial in analytical chemistry and regulatory science.
Traditional methods rely on multiple repetitive experiments, which can be unreliable with small sample sizes (e.g., 5 experiments).

Purpose:

To present FUMI theory, a new method for estimating measurement precision.
To demonstrate that FUMI theory can provide reliable precision estimates from a single measurement.

Summary:

FUMI theory estimates precision using only a single measurement of noise and signal.
This method bypasses the need for repetitive experiments, addressing the poor reliability associated with small sample sizes.
The statistical reliability of precision determined by FUMI theory is comparable to that obtained from 50 repetitive experiments.

Impact:

Enhances the reliability of precision assessment in instrumental measurements.
Offers a more efficient and statistically robust alternative to traditional repetitive methods.
Supports critical applications in regulatory science by improving the accuracy of detection limits and confidence intervals.
