Significance of Intraday precision
Intraday precision is the evaluation of an analytical method's repeatability by assessing the consistency of test results when the same sample is analyzed multiple times within a single day. This is measured as the percentage of relative standard deviation (%RSD) and indicates how reliably a method performs under the same conditions, ensuring that the results of analyses conducted on the same day remain consistent. Accurate assessments of intraday precision are crucial for validating the reliability of analytical methods.

The concept of Intraday precision in scientific sources
Intraday precision measures the reliability and consistency of analytical results from the same sample analyzed multiple times in one day, assessing repeatability under the same conditions to ensure accurate method performance.
From: Asian Journal of Pharmaceutics
(1) The precision of the method within the same day, assessed by multiple injections of the same standard and expressed as % RSD.[1] (2) It was studied using three different concentrations of EPL on the same day.[2] (3) Evaluated using the results of six replicate injections of standard concentrations.[3]
From: International Journal of Environmental Research and Public Health (MDPI)
(1) A measure of the consistency of the analytical method when repeated measurements are performed within the same day, which for the technique used did not exceed 7.8% as a coefficient of variation.[4]
