QTOF Mass Spectrometer

Lub QTOF Mass Spectrometer yog ib lub cuab yeej sib xyaw ua ke uas muaj kev ua haujlwm siab thiab sib xyaw ua ke quadrupole (Q) mass filtering nrog time-of-flight (TOF) mass analysis. Nws ua haujlwm los ntawm kev xaiv cov ions uas xav tau ua ntej los ntawm quadrupole, tom qab ntawd ntsuas lawv cov mass-to-charge ratios (m/z) los ntawm kev kuaj pom TOF raws li qhov sib txawv ntawm lub sijhawm ya ion. Qhov kev tsim ob theem no sib xyaw ua ke qhov kev xaiv mass zoo kawg nkaus ntawm quadrupole technology nrog rau qhov kev daws teeb meem siab heev thiab qhov muaj peev xwm ntawm TOF analysis.
