NEUTRAL-ION CORRELATION-MEASUREMENTS - A NOVEL TANDEM MASS-SPECTROMETRY DATA ACQUISITION MODE FOR TANDEM MAGNETIC-SECTOR REFLECTRON TIME-OF-FLIGHT INSTRUMENTS

A new instrument concept for tandem mass spectrometry is described. Th e instrument consists of a high-performance magnetic sector (Kratos MS -50) as MS-I and a reflection time-of-flight as MS-II. The instrument concept is compatible with pulsed and continuous ionization sources. T his paper describes the basic instrument concept and presents prelimin ary data for tandem mass spectrometry experiments. This paper emphasiz es the use of neutral-ion correlation measurements for obtaining metas table ion and collision-induced dissociation spectra by using a contin uous ion source.
