Cov Pob Khoom Siv Santai Huab Cua & Accessories

Tsis yog, qhov kawg-capped silica yog insoluble nyob rau hauv ib txwm siv organic kuab tshuaj.

Rau kev ua kom huv siab zoo tshaj plaws nrog C18 flash rau txhua, thov ua raws cov kauj ruam no:
① yaug cov kab ntawv nrog 100% ntawm cov muaj zog (organic)
② yaug cov kab ntawv nrog 50% muaj zog + 50% aqueous (yog tias ntxiv yuav tsum tau, suav nrog lawv) rau lwm 3 - 5 CVS.
③ yaug cov kab ntawv pib nrog kev pib ua ntej rau 3 - 5 CVS.

Rau kem loj nruab nrab ntawm 4G thiab 330G, txheem Luer txuas yog siv rau hauv cov kab ntawv flas. Rau kab loj ntawm 800g, 1600G thiab 3000g, ntxiv txuas cov adapters adapters yuav tsum tau siv rau mount cov kab ntawv loj loj no ntawm lub nyem chromatogy system. Thov saib cov ntaub ntawv Santai cov khoom lag luam rau 800g, 1600G, 3kg Flash kab rau cov ntsiab lus ntxiv.

Rau kem ib txwm muaj, nws raug nquahu kom siv lub xov tooj ntawm tes uas qhov sib piv ntawm methanol tsis tshaj 25%.

Feem ntau, nws raug nquahu kom siv lub xov tooj ntawm tes uas qhov sib piv ntawm cov polar cov kuab tshuaj tsis tshaj 5%. Cov kuab tshuaj polar suav nrog DMSO, DMF, THF, tshuaj yej thiab lwm yam.

Cov qauv coj mus los loading yog cov txheej txheem tseem ceeb los thauj cov qauv uas yuav ua kom huv rau ib kem, tshwj xeeb rau cov qauv ntawm cov tsis muaj txiaj ntsig. Hauv qhov no, ilok flash cartridge yog qhov kev xaiv tsim nyog heev.
Feem ntau, cov qauv yog yaj nyob rau hauv cov kuab tshuaj uas tsis haum thiab adsorbed mus rau ib qho adsorbant uas yuav yog tib yam li siv nyob rau hauv cov av flash lossis silica lossis lwm yam ntaub ntawv. Tom qab tshem tawm / evaporation ntawm cov kuab tshuaj uas seem, tus adsorbent yog muab tso rau saum toj ntawm ib nrab uas tau sau cia lossis nkag mus rau hauv ib qho khoom ntim khoom ruaj khov. Yog xav paub cov ntaub ntawv ntxaws ntxiv, thov saib cov ntaub ntawv Ilok-Sl Cartridge Tus Neeg Siv Phau Ntawv Qhia rau cov lus qhia ntxiv.

Sab ntim yog kwv yees li sib npaug zos (VM) thaum tsis quav ntsej cov ntim ntxiv hauv lub tubings txuas nrog lub injector thiab cov ntes.

Lub sijhawm tuag (TM) yog lub sijhawm uas xav tau rau kev lees paub ntawm ib qho kev tsis raug cai.

Cov ntim tau (VM) yog qhov ntim ntawm lub xov tooj ntawm tes yuav tsum tau ua rau kev lees paub ntawm ib qho kev tsis tuaj yeem. Lub ntim tuag tuaj yeem suav los ntawm cov kab sib luag hauv qab no: VM = F0 * tm.

Ntawm cov kab zauv saum toj saud, F0 yog tus nqi txaus ntawm theem mobile.

Tsis yog, qhov kawg-capped silica yog insoluble nyob rau hauv ib txwm siv organic kuab tshuaj.

Silica Silica flash txhua yog pov tseg thiab rau ib qho kev siv, tab sis nrog kev tuav kom tau, lub thawv silica cartridges tuaj yeem rov qab siv dua yam tsis tau txais kev ua haujlwm.
Txhawm rau rov qab siv dua, cov Silica Flash Sab hauv yuav tsum tau tsuas yog qhuav los ntawm kev nqus cua ploted lossis yaug nrog thiab khaws cia hauv isopropanol.

Qhov kev cia khoom kom tsim nyog yuav pub rau CI18 flash rau txhua tus kom tau siv dua:
• Tsis txhob cia kab ntawv kom qhuav tom qab siv.
• Tshem tawm tag nrho cov organic modifiers los ntawm yaug lub yaug lub kab nrog 80% methanol lossis acetonitrile hauv dej rau 3 - 5 CVS.
• Khaws cov kab ntawv hauv kab ntawv saum toj no yaug yaug nrog kawg fittings nyob rau hauv qhov chaw.

Rau cov kab loj loj saum 220g, cov thermal nyhuv yog pom tseeb nyob rau hauv cov txheej txheem ntawm kev ua ntej-equilibrium. Nws raug nquahu kom teeb tsa tus nqi txaus ntawm 50-60% ntawm cov lus pom zoo nrog cov txheej txheem txaus hauv kev ua ntej-sib npaug ntawm cov khoom siv thermal.

Lub thermal nyhuv ntawm cov kuab tshuaj sib xyaw yog qhov pom tseeb dua li cov kuab tshuaj. Nqa cov solvent system cyclohexane / Ethyl acetate ua piv txwv, nws tau hais tias siv 100% cyclohexane nyob rau hauv preclohexane nyob rau hauv pre-confilibrium txheej txheem. Thaum ua ntej sib txig ua tiav, kev sib cais ua haujlwm tuaj yeem ua raws li cov tswv yim preset.
