Kev suav cov kua dej yog ib qho cov txheej txheem tshuaj ntsuamuas yog txhais los ntawm kev koom ua ke ntawm radiolabeled analyte rau hauv ib qho kev faib tawm nrog cov kua tshuaj nruab nrab muaj peev xwm hloov lub zog kinetic ntawm nuclear emissions rau hauv lub teeb zog.

txhais li cas los ntawm kev suav cov kua nplaum?

Kev suav cov kua hluav taws xob (LSC) yog tus qauv kuaj txoj hauv kev los ntsuas cov xov tooj cua ntawm cov xov tooj cua tsis tshua muaj hluav taws xob, feem ntau yog beta-emitting thiab alpha-emitting isotopesCov txheej txheem ntsuas LSC xav tau Cocktails tshwj xeeb los nqus lub zog rau hauv lub teeb pom kev pom.

LSC siv rau dab tsi?

LSC tuaj yeem siv rau suav cov qauv ntaulossis suav cov qauv qis rau lub sijhawm suav ntev. Txhawm rau kom nrawm qhov no thiab tshem tawm txoj haujlwm tsis txaus ntseeg ntawm kev suav ntau tus qauv, automated ntau tus qauv LSC systems tau tsim.

Puas yog Cov Tshuaj Tseem Ceeb siv hauv kev suav cov kua dej?

Lub ntsiab lus (lossis thawj fluor) nqus lub zog los ntawm cov kuab tshuaj thiab tawm lub teeb. Qee cov thawj scintillators suav nrog p-bis-(omethylstyryl) benzene (abbreviated li bis-MSB) thiab 2, 5-diphenyloxazole (tseem hu ua PPO).

Dab tsi yog kua dej cawv cawv?

Txhua cov kua dej cawv muaj cov tsawg kawg yog cov kuab tshuaj organic thiab ib lossis ntau dua scintillators. Qhov loj ntawm LSC cocktails, lub npe hu ua emulsifying cocktails, muaj kev sib xyaw ntawm surfactants (detergents) kom muaj peev xwm tuav cov qauv aqueous.
