Detection limit - Wikipedia
Rather than performing the complete analysis of seven identical samples, if the Instrument Detection Limit is known, the MDL may be estimated by multiplying the Instrument Detection Limit, or Lower Level of Detection, by the dilution prior to analyzing the sample solution with the instrument.

4.7: Detection Limits - Chemistry LibreTexts
The IUPAC definition for the detection limit is the smallest signal for which we can say, at a significance level of α, that an analyte is present in the sample; however, failing to detect the analyte does not mean it is not present in the sample.

Limit of detection, limit of quantification and limit of blank - EFLM
• The detection limit of the measurement system/instrument and of the method should be kept apart. The detection limit of the measurement system is determined by presenting the system directly with the reagent blank or with other types of samples.

Chromatographic Measurements, Part 5: Determining ... - Separation Science
Q: What is the formula for limit of detection (LOD)? A: According to ICH Q2 (R1), the LOD is calculated as LOD = 3.3 × σ / S, where σ is the standard deviation of the response and S is the slope of the calibration curve.

IUPAC - limit of detection (L03540)
The limit of detection, expressed as the concentration, c L, or the quantity, q L, is derived from the smallest measure, x L, that can be detected with reasonable certainty for a given analytical procedure.

Limit of Detection (LOD) Calculations: 3σ Method vs IUPAC Guidelines
Two popular approaches to calculating LOD are the 3σ method and the International Union of Pure and Applied Chemistry (IUPAC) guidelines. Both methods offer valuable insights but differ in their application and interpretation.
