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 ...

The principle of concrete maturity offers a non-destructive approach to estimate strength, crucial for timely decisions in ...

Moreover, quantitative analytical methods — that is, HPLC and GC analysis — introduced to undergraduates often employ the usual addition method in which the peak intensity is associated with a ...

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 ...
