Limit of Quantitation definition

Limit of Quantitation or “LOQ” means a measurement of the concentration of a contaminant obtained by using a specified laboratory procedure calibrated at a specified concentration above the method detection level. It is considered the lowest concentration at which a particular contaminant can be quantitatively measured using a specified laboratory procedure for monitoring of the contaminant. This term is also sometimes called limit of quantification or quantification level.

Limit of Quantitation or “LOQ” means the lowest concentration at which the analyte can not only be reliably detected but at which some predefined goals for bias and imprecision are met.

Limit of Quantitation or “LOQ” means the minimum concentration of an analyte in a specific matrix that can be reliably quantified while also meeting predefined goals for bias and imprecision.

Examples of Limit of Quantitation in a sentence

• For pollutants with water quality-based effluent limits below the Limit of Quantitation (LOQ) in this permit, the LOQ calculated by the permittee and reported on the Discharge Monitoring Reports (DMRs) is incorporated by reference into this permit.

• Concentrations less than the Limit of Quantitation (LOQ) and greater than or equal to the Limit of Detection (LOD) shall be reported by the permittee on the discharge monitoring report forms as the actual measured value.

• Limit of Quantitation: For quantitative assays, the lowest concentration at which the identity and concentration of the measurand can be accurately established.

• Effluent concentrations greater than or equal to the LOD but less than the Limit of Quantitation (LOQ) shall be reported on the discharge monitoring report forms as the measured value.

• Limit of Quantitation (LOQ)The minimum levels, concentrations, or quantities of a target variable such as an analyte that can be reported with a specific degree of confidence.The calibration point shall be at or below the LOQ.
