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 ...
Our view of the ancient past is set to become a bit clearer after an international team of scientists completed a major recalibration of radiocarbon dating. The seven-year global effort used almost 15 ...
Changes in calibration curves from one time to the next, caused by drift, often require measuring devices to be recalibrated at frequent intervals. In such situations the usual practice is to estimate ...
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 web application is designed to process ICP-MS calibration and sample data from Excel files. To use it, download the template file, fill in your calibration and sample measurements, then upload it ...
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 ...
