Hauv ascending chromatography , lub sij hawm mobile cais cov sib tov los ntawm kev tsim txiaj ntawm capillary kev txiav txim (cov theem mobile txav mus rau sab saum toj tiv thaiv lub ntiajteb txawj nqus). Hauv nce chromatography , theem mobile txav downwards los ntawm kev tsim txiaj ntawm lub ntiajteb txawj nqus.
Tsis tas li ntawd, dab tsi yog descending paper chromatography?
Daim ntawv Chromatography Descending Txoj Kev The nqis txheej txheem yog ib tug complex teeb. Lub sijhawm txawb yuav maj mam txav mus rau hauv qab nqa qhov chaw ntawm cov qauv ntsuas raws li ntawv . Lub sij hawm nqis yog muab vim kev sib cais los yog kev loj hlob ntawm lub chromatogram yog coj qhov chaw ntawm down.
Dab tsi yog qhov hnyav tshaj plaws rau daim ntawv chromatography? Npaj muaj cov kuab tshuaj rau daim ntawv Chromatography
| Solvent | Polarity (qhov ntsuas qhov ntsuas ntawm 1-5) | Kev tsim nyog |
|---|---|---|
| Dej | 1 - Feem ntau cov polar | Zoo |
| Rubbing cawv (ethyl type) lossis denatured cawv | 2 - Siab polarity | Zoo |
| Rubbing cawv (isopropyl hom) | 3 - Nruab nrab polarity | Zoo |
| Vinegar | 3 - Nruab nrab polarity | Zoo |
Xav txog qhov no, dab tsi cuam tshuam rau daim ntawv chromatography?
Khaws cia yam muaj nuj nqis nyob rau hauv nyias txheej chromatography cuam tshuam los ntawm absorbent, hnyav, lub chromatography phaj nws tus kheej, daim ntawv thov txheej txheem thiab qhov kub thiab txias ntawm cov kuab tshuaj thiab phaj.

Dab tsi yog qhov txawv thiab zoo sib xws ntawm kab chromatography thiab TLC?
Lub ntsiab 'qhov txawv ntawm' ob qho no yog tias 'thin txheej chromatography' siv cov theem sib txawv ntawm cov kab chromatography. Lwm qhov sib txawv yog tias 'thin txheej chromatography' tuaj yeem siv los paub qhov txawv ntawm cov khoom sib txawv uas tsis tuaj yeem ua tau hauv kab chromatography
Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
