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

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 ...

Researchers have produced a new archaeological tool which could answer key questions in human evolution. The new calibration curve, which extends back 50,000 years, is a major landmark in radiocarbon ...

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 ...
