Research output: Contribution to journalArticle


A modern construction peak selector based on digital techniques has been constructed. The instrument can be extended to a maximum of nine signal channels selecting the ion-current with the help of thumbwheel switches. In the first channel it is possible to set the full mass range, while in each of the other eight channels a width of a maximum of nine atomic mass units can be set. The instrument has got a mass identifier circuit and optionally each channel has a fast analog signal processing unit. The peak selector can be coupled to any kind of quadrupole mass spectrometer with a maximum mass range up to 512 amu.
