Cov lub hom phiaj ntawm ntawv chromatography yog cais ib qho sib tov rau hauv nws cov khoom sib txawv. Siv cov qauv uas yog sib xyaw ntawm ntau yam xim, xws li cov xim pleev xim orleaf, tso cai rau tus kws tshawb fawb pom cov khoom sib cais.
Cov lus nug tseem yog, lub hom phiaj ntawm daim ntawv chromatography yog dab tsi?
Cov lub hom phiaj ntawm chromatography nyob rau hauv generalis kom cais cov molecules raws li qhov sib txawv ntawm qhov loj me, them orpolarity, thiab solubility. Daim ntawv chromatography yog nodifferent; nws siv ntawv raws li cov theem nyob ruaj ruaj thiab asolvent raws li lub sij hawm mobile.
Tsis tas li, vim li cas peb thiaj siv cov ntawv lim hauv chromatography? Nws yog siv los ntsuas qhov muaj ntau yam khoom siv, saib xyuas tus nqi thiab kev nce qib ntawm cov tshuaj tiv thaiv lossis txiav txim siab qhov purity ntawm cov khoom. Lim ntawv impregnated nrog hnyav yog feem ntau siv kom saturate thedevelopment chamber's air with solvent vapor so the stationaryphase doesn't dry during the process.
Tsis tas li ntawd, lub hom phiaj ntawm Chromatography & Spectroscopy sim yog dab tsi?
Chromatography yog siv rau kev sib cais ntawm amixture ntawm cov tebchaw rau hauv nws tus kheej cov khoom. Muaj ntau txoj hauv kev los ua kom tiav qhov no tab sis ib yam uas txhua tus chromatography kev sib koom ua ke yog kev siv lub sijhawm txawb thiab lub sijhawm nyob ruaj khov.
Tus nqi Rf yog dab tsi?
Cov Rf nqi yog txhais raws li qhov sib piv ntawm qhov deb txav los ntawm qhov solute (xws li cov dye lossis pigment nyob rau hauv kev sim) thiab qhov kev ncua deb txav los ntawm cov kuab tshuaj (hu ua Solventfront) nyob rau hauv daim ntawv, qhov twg ob qho tib si deb yog ntsuas los ntawm lub hauv paus chiv keeb los yog daim ntawv thov Baseline, uas yog lub ntsiab lus uas tus qauv yog

Lub hom phiaj ntawm kev sim ticker timer yog dab tsi?
Lub ticker daim kab xev timer ua haujlwm los ntawm kev ua cov dots ntawm daim kab xev ntawm lub sijhawm sib npaug (kwv yees txhua 0.1s hauv qhov kev sim no). Nws yog ib txoj hauv kev zoo tshaj plaws rau cov tub ntxhais kawm physics pib kom paub txog kev ntsuas kev txav. Cov menyuam kawm ntawv yuav sau thiab teev cov lus tsa suab ntawm lub tsheb uas txav mus tas li
Dab tsi yog qhov txawv ntawm daim ntawv qhia lub hom phiaj thiab daim ntawv qhia lub hom phiaj tshwj xeeb?
Qhov tseem ceeb hauv daim ntawv qhia dav dav yog nyob ntawm qhov chaw. Phab ntsa daim duab qhia chaw, feem ntau daim ntawv qhia pom nyob rau hauv atlases, thiab txoj kev maps yog tag nrho cov nyob rau hauv qeb no. Thematic maps, tseem hu ua daim ntawv qhia tshwj xeeb, qhia txog thaj chaw faib khoom ntawm ib lub ntsiab lus lossis qhov tshwm sim
Lub hom phiaj ntawm cov ntaub ntawv kev nyab xeeb yog dab tsi?
Lub hom phiaj. Daim Ntawv Qhia Txog Kev Nyab Xeeb (yav tas los hu ua Material Safety Data Sheet) yog ib daim ntawv qhia ntxaws ntxaws uas tau npaj los ntawm cov chaw tsim khoom lossis cov neeg xa khoom ntawm cov tshuaj lom neeg. Nws piav qhia txog lub cev thiab tshuaj lom neeg ntawm cov khoom
Lub hom phiaj ntawm kev txiav txim siab ntawm ib qho kev sib npaug tas li yog dab tsi?
Lub hom phiaj ntawm qhov kev sim no yog txhawm rau txiav txim siab qhov sib npaug tsis tu ncua rau cov tshuaj tiv thaiv. Fe3+ + SCN. & rho tawm; ⇌ FeSCN2+ thiab saib seb qhov tas mus li yog qhov tseeb tib yam hauv qab sib txawv. tej yam kev mob
Hom phiaj phiaj xwm phiaj xwm yog Mercator daim ntawv qhia?
Mercator projection. Mercator projection, hom phiaj xwm phiaj xwm qhia hauv 1569 los ntawm Gerardus Mercator. Nws yog feem ntau piav raws li ib tug cylindrical projection, tab sis nws yuav tsum tau muab los ntawm lej
