calibration curve


Also found in: Encyclopedia, Wikipedia.

calibration curve

the graphic or mathematic relationship between the readings obtained in an analytic process and the quantity of analyte in a calibration. The relationship is often a straight line rather than a curve.

Originally, 4 to 14 representative spectra (selected by visual estimate of the distribution of the colors in the maps) were extracted from each of the discrete composition peak-ratio maps for use in the calibration curve.
A calibration curve of gallic acid was plotted to measure the amount of phenolic compounds in limau kasturi peels extract.
Considerations must include matching the quality control target values for the given method, number of levels to ensure multi-point calibration curves are appropriately assessed, risk of harm to the patient, independence from instrument calibrators, and data management/peer group comparison solutions.
Calibration curve samples were processed with each batch and used to determine the concentration of IGF-1.
Furthermore, we have compared the samples taken from the lake with other calibration curves made in recent years based on measurements of stalactites, stalagmites and corals,' explains Van der Plicht.
Constantz and Murphy (1990) demonstrated that TDR could reasonably measure changes in moisture content in several species of living trees over time, though they showed that the calibration curve for determining moisture content of trees was different from the general calibration curve used for determining moisture content of soil.
The parameters calculated from the data of less than 500 s from the start of the reaction were not applicable for system calibration as the slope of the calibration curve was very small (below 0.
The new calibration curve, which extends back 50,000 years, is a major landmark in radiocarbon dating - the method used by archaeologists and geoscientists to establish the age of carbon-based materials.
We have used three IDs for calibration because the interface has to read three times calibration curve (for each measured parameter, the curve is different).
Calibration (the degree of agreement between predicted mortality determined by the model and actual mortality) was tested using the Hosmer-Lemeshow goodness-of-fit H and C statistics (23), calibration curve analysis and standard mortality ratio.
