Gas chromatography–mass spectrometry (GC-MS) yog ib qho kev tshuaj ntsuam xyuas uas muab cov yam ntxwv ntawm cov roj chromatography thiab huab hwm coj spectrometry rau txheeb xyuas cov khoom sib txawv hauv cov qauv ntsuas. … Zoo li cov kua chromatography–mass spectrometry, nws tso cai rau kev tsom xam thiab nrhiav tau txawm tias me me ntawm ib yam khoom.
Dab tsi yog qhov txawv ntawm pawg spectrometry thiab chromatography?
Thaum cov kua chromatography sib cais sib xyaw nrog ntau yam khoom, huab hwm coj spectrometry muab cov txheej txheem tus kheej ntawm tus kheej cov khoom uas muaj qhov tshwj xeeb molecular thiab kev tshawb pom rhiab heev.
Vim li cas huab hwm coj spectrometry siv nrog roj chromatography?
Kev tshuaj ntsuam me me thiab tsis hloov pauv cov molecules
Thaum ua ke nrog kev tshawb pom lub zog ntawm huab hwm coj spectrometry (MS), GC-MS tuaj yeem yog siv los cais cov sib xyaw ua ke, quantify analytes, txheeb xyuas qhov ncov tsis paub thiab txiav txim siab kab mob ntawm cov kab mob.
Chromatography loj spectrometry ua haujlwm li cas?
GC ua haujlwm ntawm txoj cai uas sib tov yuav sib cais ua ib tus neeg thaum rhuab. … Raws li cov khoom sib cais tawm ntawm kab qhib, lawv ntws mus rau hauv MS. Mass spectrometry txheeb xyuas cov tebchaw los ntawm qhov loj ntawm cov analyte molecule.
Qhov txawv ntawm HPLC thiab LC-MS yog dab tsi?
Nyob rau hauv xaus, HPLC yog ib tug kua chromatography txoj kev whereas LCMS yog ib tugua ke ntawm cov kua chromatography thiab huab hwm coj spectrometry. Ob txoj kev tshuaj ntsuam xyuas no muaj cov yam ntxwv sib txawv, tab sis lawv tuaj yeem siv los txheeb xyuas thiab txheeb xyuas cov khoom noj muaj pes tsawg leeg, tshuaj, thiab lwm yam bioactive molecules.
