4.Quality analyzer

Quality analyzer: yakashongedzerwa nepamusoro-chaiyo yese simbi quadrupole ine pre quadrupole

Iyo quadrupole yakagadziridzwa kudzora tembiricha, iyo inogona kuve nechokwadi chekudzikama zviratidzo pasina kudiwa kwekutonga tembiricha.

Pre quadrupole detachable uye inowachwa kudzivirira kusvibiswa kweiyo main quadrupole

Iyo quadrupole yakagadziridza ion simba tekinoroji, iyo inogonesa kumhanya kweiyoni inopfuura nepakati peiyo quadrupole uye inovandudza chiratidzo chechiratidzo.

5.Detector

Hupenyu hurefu nhanho 13 yakapararira dynodeelectronic multiplier

Yakashongedzerwa ne10kV inoshandura dynode uye lens system yekubvisa kwayakarerekera ruzha
