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 ...

Question: How many measurement scientists does it take to screw in an LED lightbulb? Answer: For researchers at the National Institute of Standards and Technology (NIST), half as many as it took a few ...

Calibration is the process of assigning engineering units and uncertainties to digital counts (or meter deflections if measuring a current/voltage/resistance, etc ...

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 ...
