Abstract
The invention relates to the removal of electronic noise from mass spectra which are scanned as single spectra and added together to give a sum spectrum. The invention consists in removing the noise in the single spectra and not in the sum spectrum since ion signals and electronic noise can only be distinguished in the single spectra.
Claims9
Method for the acquisition of mass spectra of improved quality in mass spectrometers in which many individually digitized spectra are scanned and added to form a sum spectrum, wherein the electronic noise is removed by a computer algorithm routine from the single spectra before the single spectra are added to form the sum spectrum.
Transient recorder for the acquisition of mass spectra comprising a scanning apparatus by which many individually digitized spectra are scanned and added to form a sum spectrum, wherein the electronic noise is removed by a computer algorithm routine from the single spectra before the single spectra are added to form the sum spectrum.
