|Linked scan at constant B(1-(E/E0))1/2/E|
This can be performed with a sector instrument incorporating at least one electric sector plus one magnetic sector. The magnetic sector field strength, B, and the electric sector field strength, E, are scanned simultaneously, while holding the accelerating voltage , V, constant, so as to maintain the ratio B [1- (E /E 0)]1/2 /E constant. This constant value is equal to B3/E0, where E0 and B3 are respectively the electric and magnetic sector fields required to transmit M3+ ions in the main ion beam; m3 represents the mass (m1-m2) of the selected neutral fragment M3 whose precursor spectrum is required. The fragmentation reactions thus observed occur in a field-free region traversed before the two sectors scanned in this way. The term 'B [1- (E /E 0)]1/2/E linked scanâˆšÃ‰Â¬Â¢âˆšÂ¢â€šÃ„Ã¶Â¬Â¨âˆšÂ¢â€šÃ„Ã»Â¬Â¢ is not recommended.
