Meaning of LOQ | Babel Free

Definitions

Limit of quantification (or limit of quantitation); the lowest concentration of a substance that can be accurately measured under specified experimental. conditions.

initialism

Examples

“Therefore LOD and LOQ evaluation is only necessary for water.”

“For this reason, many regulatory agencies define another limit, the limit of quantitation (LOQ), which is higher than the LOD and should have better precision.”

“It is generally accepted that the LOQ is linked to method performance expectations including accuracy and precision.”

“The required precision for the LOQ is determined (usually = 10%), and for this value the concentration equal to the LOQ is read on the graph.”

“Values above the limit of quantification (LoQ) were only obtained in the 'fish' and 'alcoholic beverages' groups, but mean concentration levels in the latter group were very low (4/<gkg~1)4 in comparison to those obtained for the fish group.”

“If the reproducibility (CV <15%25) and accuracy (>80%) meet a prespecified value, the LoQ is validated.”

“The empirical method is the same procedure as above for determination of LoQ but defined as the concentration at which all acceptance criteria are met and the quantitative value is within +-20% of the target concentration (i.e., CV criteria that was earlier discussed).”
