4.Quality analyzer

Isihlaziyi sekhwalithi: ifakwe ngokunemba okuphezulu yonke i-quadrupole yensimbi ene-pre quadrupole

I-quadrupole ilungiselelwe ukulawula izinga lokushisa, elingaqinisekisa izinkomba zokuzinza kwekhwalithi ngaphandle kwesidingo sokulawula izinga lokushisa

I-pre quadrupole iyahlukaniseka futhi iyawasheka ukuze kugwenywe ukungcoliswa kwe-quadrupole eyinhloko

I-quadrupole ithuthukise ubuchwepheshe be-ion energy, obukhulisa isivinini sama-ion adlula ku-quadrupole futhi ithuthukise ikhwalithi yesiginali.

5.Umtshina

Impilo ende yezinga le-13 ehlakazekile i-dynodeeisiphindaphindi se-lectronic

Ifakwe i-dynode yokuguqula engu-10kV kanye nesistimu yelensi yokususa umsindo ophakathi nendawo

6.Isistimu ye-vacuum
