PCB ion trap mass analyzer txais yuav cov kab hluav taws xob tso tawm txheej txheem, nws cov electrode tau ua tiav los ntawm PCB, thiab nws txoj kab hla tau tsim los ua cov duab plaub. Yog vim li cas rau kev lees paub qhov kev tsim no yog raws li hauv qab no: ua ntej, kab tawm ion ntxiab muaj peev xwm khaws cov ion ntau dua thiab ion ntes tau zoo dua li cov cuab yeej peb-dimensional, yog li nws muaj kev nkag siab siab dua hauv kev tshuaj xyuas thiab nrhiav pom; Qhov thib ob, lub duab plaub yog ib qho ntawm cov qauv yooj yim tshaj plaws, uas yooj yim heev rau kev ua haujlwm thiab sib dhos. Thib peb, PCB tus nqi qis, ua cov thev naus laus zis thiab txheej txheem paub tab.

PCB ion trap muaj ob khub ntawm PCB hluav taws xob thiab ib khub hlau kawg hau hluav taws xob. Txhua PCB electrodes yog 2.2 hli tuab thiab ntev 46mm. Qhov saum npoo ntawm txhua PCB electrode yog tshuab ua peb ntu: 40mm nruab nrab cov hluav taws xob thiab ob lub 2.7mm kawg electrodes. Daim kab xev insulating dav 0.3 hli tau ua haujlwm nruab nrab ntawm cov hluav taws xob nruab nrab thiab ob qhov kawg hluav taws xob kom cov hluav taws xob sib txawv tuaj yeem thauj khoom hauv nruab nrab cov hluav taws xob thiab ob qhov kawg electrodes feem. Plaub qhov tso rau qhov nrog txoj kab uas hla ntawm 1 hli tau ua tiav ntawm cov electrodes ntawm ob qho kawg rau kev sib dhos ion ntxig. Qhov kawg npog electrode yog ua los ntawm cov hlau tsis huv uas muaj tuab li 0.5 hli thiab ua tiav rau hauv cov duab tshwj xeeb, yog li nws tuaj yeem ua tau zoo sib xws nrog qhov chaw nyob ntawm ob qho kawg ntawm PCB hluav taws xob los tsim PCB PCB ntxiab.

Thaum lub tshuab ntxhua khaub ncaws ion ua haujlwm, qhov siv hluav taws xob hluav taws xob tau siv rau hauv nruab nrab cov hluav taws xob ntawm PCB los tsim hluav taws xob hluav taws xob AC txuas hluav taws xob, thaum dc qhov hluav taws xob tau siv rau ob qhov kawg hluav taws xob los tsim ib qho axial DC khi hluav taws xob. Lub qhov nrog txoj kab uas hla ntawm 3 hli tau ua tiav hauv nruab nrab ntawm txhua qhov kawg lub hau hluav taws xob. Ions tsim los ntawm cov peev txheej sab nraud tuaj yeem nkag mus rau hauv qhov ntxiab ion los ntawm lub qhov kawg ntawm lub hau hluav taws xob kawg, thiab raug khi thiab khaws cia hauv cov cuab yeej ion nyob rau hauv kev sib koom ua ke ntawm radial AC khi hluav taws xob thiab axial DC khi hluav taws xob. Ib ntawm ob khub ntawm PCB cov tshuab hluav taws xob tau ua haujlwm nruab nrab nrog qhov dav 0.8 hli raws li qhov rho tawm cov channel, uas yog siv los xaiv qhov tso tawm cov ions khaws cia hauv cov ntxiab ion tawm ntawm cov cuab kom pom thiab tshuaj xyuas zoo.
