Los ntawm cov qauv ntawm feem ntau ntawm lwm yam kev siv lub cev, huab hwm coj spectrometry yog qhov haumxeeb, xav tau qhov chaw ntawm qis picomoles thiab nanomoles ntawm cov khoom, nyob ntawm seb txoj kev ionization ua haujlwm, tab sis tawm tsam qhov no yuav tsum tau teeb tsa nws qhov kev puas tsuaj. nature.
Dab tsi yog qhov tsis zoo ntawm pawg spectrometry?
Qhov tsis zoo ntawm huab hwm coj spec yog nws tsis zoo heev ntawm kev txheeb xyuas cov hydrocarbons uas tsim cov ions zoo sib xws thiab nws tsis tuaj yeem qhia qhov muag pom thiab geometrical isomers sib nrug. Qhov tsis zoo yog them rau los ntawm kev sib txuas MS nrog lwm cov tswv yim, xws li roj chromatography (GC-MS).
Puas huab hwm coj spectrometry rhuav tshem tus qauv?
Cov lus teb tsis yog, koj tus qauv raug rhuav tshem thaum lub sijhawm tshuaj ntsuam. … Molecules nyob rau hauv koj tus qauv ua ionized, nkag mus rau lub loj spectrometer, thiab nws thiaj li sib tsoo nrog cov loj analyzer electrodes.
Puas yog pawg spectroscopy puas tsuaj?
Secondary ion mass spectroscopy (SIMS) yog destructive analytical txheej txheem hauv uas cov khoom raug tshem tawm ntawm qhov chaw los ntawm ion beam sputtering, thiab cov txiaj ntsig zoo thiab tsis zoo ions raug tshuaj xyuas ntau. hauv ib pawg spectrometer [62].
Puas spectrometry puas tsuaj?
Hmoov tsis zoo mass spectrometry yog txheej txheem kev puas tsuaj, uas tsis zoo tagnrho hauv kev tshawb nrhiav pov thawj yog tias muaj qee tus qauv muaj rau kev tshuaj xyuas.
