Nettet9. 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. However, r is not an appropriate measure for the linearity. NettetPrecision can have different meanings, depending on what level of variability is included.. Measurement repeatability (s repeatability, s r) expresses the closeness of the results obtained with the same sample (or subsamples of the same sample) using the same measurement procedure, same operators, same measuring system, same operating …

Most variable wavelength HPLC UV/Vis detectors have a band of light, e.g. 254 nm ± 2 nm, determined by the slit width. This is one of the causes of limited linearity in UV/Vis tunable HPLC detectors. Background absorbance also influences the working range of the detector. companies that use sweatshops
