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 ...

The physical properties and behaviours of polymers are based strongly on the properties of the polymer molecules themselves. The behaviour of the material is influenced by the molecular size and ...

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 ...

It is a stringent requirement for all quality systems to calibrate the equipment used for measurements. The International Vocabulary of Metrology defines the term calibration as an “operation that, ...
