Web13 mrt. 2024 · Use the equation of the calibration curve to adjust measurements taken on samples with unknown values. Substitute the measured value as x into the equation and solve for y (the “true” value). In the example from step 2, y = 1.05x + 0.2. Thus, a measured value of 75.0, for example, would adjust to y = 1.05 (75) + 0.2 = 78.9. Cite this Article.

WebFor linear calibration, it is sufficient to control the end-points and the middle of the calibration interval to ensure that the instrument does not drift out of calibration. Therefore, check standards are required at three points; namely, One measurement is needed on each check standard for each checking period. WebThe resulting calibration curve will consist of the data points for each average. If only a number and weight average are provided, the resulting calibration curve will consist of these two points plus the peak molecular weight, or a three point calibration curve. This broad standard is based on work done by Hamielec in 1969.
