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 ...

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 ...

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 ...

Matrix-matched standards are crucial for XRF accuracy. Dr. Shiv Verma outlines their impact on elemental analysis and the prevention of calibration errors.
