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

Although smartphones and other consumer cameras are increasingly used for scientific applications, it's difficult to compare and combine data from different devices. A new easy-to-use standardized ...

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 ...

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 ...

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 ...

Integrating near-infrared spectroscopy (NIRS or NIR spectroscopy) in an analysis workflow should pave the way toward realizing a fast, accurate, and non-destructive method for routine analysis. But ...
