Make the best sample under the strictest conditions to achieve the highest accuracy. Alignment of optical path, wavelength locking, temperature control... All experimental conditions must reach the highest standard. A gentleman should be cautious about starting. A minimal error or deviation may result in wide divergence. "Self-traceability" means preciseness, completing each experiment with a rigorous attitude, recording each data carefully, summarizing the rules in each experiment, and improving the process after each failure.
