Before setting an empty sleeve (2) in the spool frame a thread holding element (7) is held ready on the winding device. The thread coming from the thread delivery station is guided up to and fixed on the thread holding element which is inserted in the winding frame (3) between the empty sleeve and spool. The thread holding element is turned so that the thread reserve is wound on and the thread ext...

A method and apparatus for analyzing ions by determining times of flight include establishing an encoded sequence for launching packets of ions from a source region toward a detector. The encoded sequence is one in which the high-mass ions of a leading packet will be passed by the low-mass ions of a trailing packet. Thus, a high efficiency time-of-flight mass spectrometer is formed. The ions of ea...
