Spreadsheets are often used to perform GMP-related calculations, but can lead to serious problems and unnecessary risk. We explain why the use of spreadsheets is heavily discouraged in a regulated laboratory environment.

A Raman spectrometer’s spectral resolution is determined by its spectral dispersion in conjunction with the entrance slit width. We explain the instrument design parameters involved.

For a number of elements, spectroscopic interferences can have a significant impact on the ability to achieve low detection limits in ICP-MS. We investigate the mechanisms in multi-quadrupole ICP-MS that are designed to remove these interferences.
