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 ...
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 ...
Compared to simple laboratory tests, instrumental methods of analysis may give improved: A solution containing sodium ions gives a reading of four units on the flame photometer. Use the calibration ...
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 ...
ISO 21501-4 is a new type of international calibration standard that deals with periodic and performance calibration of light-scattering air particle counters (LSAPC or APC) throughout the service ...
