Calibration in analytical chemistry is fundamental to quantifying substances and ensuring the metrological integrity of measurement systems. By establishing a reliable relationship between the ...

Overview: This presentation will provide an overview of the rules and assumptions behind the calibration of analytical instruments. We will discuss how external standard, internal standard, and ...

Light scattering methods are often called ‘'absolute’ because the addition of a light scattering detector to an SEC system enables direct molecular weight measurement without creating a calibration ...

Changes in calibration curves from one time to the next, caused by drift, often require measuring devices to be recalibrated at frequent intervals. In such situations the usual practice is to estimate ...

This article shows how the absorbance maxima of Ponceau-S is determined over a wavelength range of 220nm to 800nm using the Eppendorf BioSpectromenter ®. The methods of analysis using this ...

Compared to simple laboratory tests, instrumental methods of analysis may give improved: A solution containing sodium ions gives a reading of four units on the flame photometer. Use the calibration ...

Motivated by calibration problems in near-infrared (NIR) spectroscopy, we consider the linear regression setting in which the many predictor variables arise from sampling an essentially continuous ...
