IMS tso

IMS A/W yog cov Ion muaj Spectrometry, suav cov neeg txhais lus rau cov ion muaj spectroscopy.

Rau ib qib qis "ion muaj spectroscopy" detectors (IMS). Cov pawg yuav tsum analyzed yog diav, ntim tshuaj thiab gasification; tom qab ntawd, tom qab evaporation ntawm cov tshuaj ntawm muaj cua huv qhuav txaus raws li lub noob, mus rau qhov zoo noj ib cov tshuaj tiv thaiv. Zoo noj cov tshuaj tiv thaiv ntawm ib tug neeg tsis muaj zog ion tau qhov twg los, npib tsib xee-63 (63Ni) Beta-cov duab tshav ib emitters. Β-hais thiab gases nyob hauv tus qauv kwj hais yuav tsim positive thiab negative ions. Heev txaus siab tsis ions, feem ntau cov tshuaj xws li heroin thiab neeg tsim muaj ions.

Raws li lub sijhawm tas ntawm IMS hos tus electric teb. Lub polarity ntawm electric teb yuav zoo los tsis zoo, muab raws seb tej detected. Ion polarity yog tau los ntawm ib tug tswj tau qhib kev daws ntawm qhov tsis zoo noj tau zoo noj.

Txawv ions mus sib txawv, tab sis nws yog peculiar tshaj tawm ntawm drift, daws thiab nyob rau lub sij hawm kom mus zoo raws cov collector electrode. Ua li no, peb cov ions uas zoo txawv (x, y, thiab z) Atlas drift, los yog waveforms nyob rau hauv daim duab, x-ion ua ntej los txog, rafting sij hawm yam tsawg kawg nkaus.
