NettetLinearity of the calibration graph is closely related to choosing the calibration model and working range. Factors affecting linearity: Firstly, the ion source behaves linearly only if the ionization efficiency of the analyte is independent of its concentration in the effluent.

NettetIn mathematics, the term linear is used in two distinct senses for two different properties: . linearity of a function (or mapping );; linearity of a polynomial.; An example of a linear function is the function defined by () = (,) that maps the real line to a line in the Euclidean plane R 2 that passes through the origin. An example of a linear polynomial in the … NettetThe results revealed a linear calibration curve in the range of 5–400 ngmL⁻¹ (r² ≥ 0.9998) with lower limit of quantification (LOQ) and lower limit of detection (LOD) of 4.66 and …

NettetStrictly speaking, we cannot test for linearity as such. The best that we can achieve is to show that a deviation from linearity is too small to detect given our results, that is, it’s not statistically significant. One approach along these lines is to examine the residuals from a linear regression. (That is a good thing to do anyway.)

Although the data certainly appear to fall along a straight line, the actual calibration curve is not intuitively obvious. The process of determining the best equation for the calibration curve is called linear regression. greendale wisconsin obituariesNettet9. feb. 2024 · Linearity of the calibration curve is usually expressed through the coefficient of correlation, r, or coefficient of determination, r 2. A correlation coefficient close to unity (r = 1) is considered by some authors’ sufficient evidence to conclude that the calibration curve is linear.
