20080197276 | MASS SPECTROMETER - An ion optical system to form a loop orbit is provided to sufficiently ensure required performance such as ion transmission efficiency while making it easy to design the system by alleviating a space-focusing condition. The loop orbit of the ion optical system is realized so as to satisfy (t|x)=(t|α)=(t|δ)=0 as the time-focusing condition and to satisfy −2<(x|x)+(α|α)<2, and −2<(y|y)+(β|β)<2 as the space-focusing condition. (x|x) and other similar terms are constants determined by the elements indicated in the parenthesis in a general expression format of the ion optical system. The conditions are substantially alleviated as opposed to the conventional space-focusing condition where each of (x|x), (α|α), (y|y) and (β|β) needs to be ±1. Thus, the parameters to decide the shape of electrodes by which the ion optical system is configured have higher degree of freedom. | 08-21-2008 |

20140249766 | METHOD AND SYSTEM FOR MASS SPECTROMETRY DATA ANALYSIS - In estimating a structural formula of an unknown substance produced through partial structural change of an original substance having a known structure caused by metabolism or the like, structural change is considered in two stages, the elimination of a partial structure and the addition of another partial structure. First, an additional partial structure is collected as known information in addition to an MS | 09-04-2014 |
