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 ...

Spectrophotometers have a long history in the scientific laboratory, primarily as devices for analyte quantification in solution. Myriad spectrophotometry applications use either the analyte’s ...

Raman spectroscopy is a popular and well-developed technique used for molecular identification. It is extensively used for qualitative analysis and it provides fast material identification, usually at ...

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 ...

Precious metal mining involves removing ore from the ground and subjecting them to a number of sample preparation methods for the extraction of the desired metals. Fire-assay is a widely used method ...

All calibrations are subject to error. It is essential to ensure that qualified instruments are employed in the regulated environment. GMPs both in the United States ...

McPherson’s grazing incidence wavelength dispersive optical spectrometer allows rapid analysis of spectral light in the ~1 to 300nm wavelength region (4 to 1200 eV.) Beside high-harmonic laser ...

Space scientists and plasma physicists who need an instrument for vacuum ultraviolet, EUV, and XUV capitalize on the McPherson 248/310 spectrometers range and flexibility. Configured in reverse, it ...
