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

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 ...

A calibration curve has been created in accordance with ASTM D4929 method to show the analysis of chlorine (Cl) in oil. The only difference in method was the use of a rhodium anode tube. The powerful ...

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 ...

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 ...

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 ...
