Kev teeb tsa thiab khiav a TLC
Ib qho me me ntawm elutant yog nchuav rau hauv thawv (mus rau qhov tob txog 1/2 txog 2/3 ntawm tus hauv qab ntawm TLC daim ntawv-rau-pib kab nrug), thiab ib daim duab plaub ntawm cov ntawv lim tso kom nws kov tus elutant thiab dag rau lub thawv phab ntsa, feem ntau saum toj no tus laug laug.
Ib yam li ntawd, koj tuaj yeem nug, koj ua li cas TLC?
A TLC phaj yog ib daim ntawv ntawm iav, hlau, los yog yas uas yog coated nrog ib tug nyias txheej ntawm cov khoom adsorbent (feem ntau yog silica los yog alumina).
Thin Layer Chromatography (TLC)
- Kauj Ruam 1: Npaj lub thawv tsim.
- Kauj ruam 2: Npaj TLC phaj.
- Kauj ruam 3: Pom lub TLC phaj.
- Kauj Ruam 4: Txhim kho lub phaj.
- Kauj Ruam 5: Pom cov chaw.
Tsis tas li ntawd, TLC tuaj yeem txhim kho chromatography li cas? nrog kev sib cais ntawm ib hom preabsorbent nyias-txheej phaj. Cov cuab yeej pom tau tias muaj txiaj ntsig zoo hauv ntau txoj kev loj hlob chromatography . Kev daws teeb meem hauv nyias-txheej chromatography ( TLC ) tuaj yeem yog txhim kho los ntawm kev txo qhov loj ntawm qhov chaw coj mus kuaj thiab nce kev sib cais ntawm cov chaw tsim kho.
Tom qab ntawd, ib tus tuaj yeem nug, TLC phaj npaj li cas?
Kev npaj phaj Lawv yog npaj los ntawm kev sib xyaw cov adsorbent, xws li silica gel, nrog me me ntawm inert binder zoo li calcium sulfate (gypsum) thiab dej. Qhov sib tov no yog kis raws li cov slurry tuab ntawm ib daim ntawv tsis muaj peev xwm, feem ntau yog iav, tuab aluminium ntawv ci, los yog yas.
Yuav ua li cas yog tias cov kab hnyav nce mus txog saum koj lub phaj TLC?
Tshuaj txav mus a TLC phaj nrog rau kuab tshuaj tau siv los tsim cov phaj . Txawm li cas los xij, yog tias cov kuab tshuaj mus txog rau saum ntawm phaj , cov tshuaj txuas ntxiv mus.

Yuav ua li cas koj txiav txim siab npaum li cas ntawm cov kua qaub uas yuav tsum tau neutralize lub hauv paus?
Kev daws qhov teeb meem Acid-Base Neutralization Kauj Ruam 1: Muab xam cov moles ntawm OH-. Molarity = moles / ntim. moles = Molarity x Volume. moles OH- = 0.02 M/100 milliliters. Kauj ruam 2: Xam qhov ntim ntawm HCl xav tau. Molarity = moles / ntim. Volume = moles/molarity. Volume = moles H+/0.075 Molarity
Dab tsi theem ntawm cov teeb meem yuav siv cov duab ntawm nws lub thawv?
Ua kua Ua kom pom qhov no, yam khoom dab tsi tsis coj cov duab ntawm nws lub thawv? khov: A yam khoom uas khaws cia nws loj thiab puab tsis muaj ib thawv ; a yam khoom nws cov molecules tsis tuaj yeem txav mus los tsuas yog vibrate.
Yuav ua li cas koj teeb tsa kab regression hauv Excel?
Peb tuaj yeem teeb tsa qhov kev thim rov qab hauv Excel los ntawm kev qhia cov ntaub ntawv thiab qhia nws raws li cov phiaj xwm tawg. Toadd ib kab regression, xaiv 'Layout' los ntawm 'Chart Tools' zaub mov. Nyob rau hauv lub dialog box, xaiv 'Trendline' thiab ces 'Linear Trendline'. Txhawm rau ntxiv tus nqi R2, xaiv 'Ntau Trendline Options' los ntawm 'Trendline menu
Vim li cas koj thiaj li yuav tsum tsis txhob nias qhov nyuaj thaum kos lub npoo coated ntawm TLC phaj?
Ua tib zoo tuav cov phaj kom zoo kom koj tsis txhob cuam tshuam cov txheej ntawm adsorbent lossis ua kom qias neeg. Saib xyuas kom tsis txhob nias nyuaj nrog cov cwj mem uas koj cuam tshuam cov adsorbent. Hauv kab, kos lub npe ntawm cov qauv uas koj yuav pom ntawm lub phaj, lossis kos cov lej rau lub sijhawm cov ntsiab lus
Thaum twg koj yuav tsum siv correlation thiab thaum twg koj yuav tsum siv yooj yim linear regression?
Regression feem ntau yog siv los tsim cov qauv / qhov sib npaug los kwv yees cov lus teb tseem ceeb, Y, los ntawm cov txheej txheem kwv yees (X) sib txawv. Kev sib raug zoo feem ntau yog siv los ua kom sai thiab ua kom luv luv cov kev taw qhia thiab lub zog ntawm kev sib raug zoo ntawm ib pawg ntawm 2 lossis ntau tus lej sib txawv
