Acetonitrile (CAS 75-05-8), tseem hu ua ACN, yog ib qho ntawm feem ntau siv HPLC mobile theem cov kuab tshuaj hauv cov chaw soj ntsuam. Nws lub cev thiab tshuaj lom neeg cov khoom ua rau nws tshwj xeeb tshaj yog haum rau high-precision chromatographic tsom xam.
Siab Solvent Strength
Acetonitrile muaj lub zog elution muaj zog, tso cai rau kev sib cais ntawm ntau yam ntawm lub ncov qaumteb qabteb thiab nruab nrab tsis yog -polar compounds. Qhov no ua rau acetonitrile rau HPLC tsom xam muaj ntau yam nyob rau hauv kev siv tshuaj, tshuaj, thiab ib puag ncig.
Tsawg viscosity, khiav ceev dua
Piv nrog rau methanol, HPLC qib acetonitrile muaj qis viscosity, uas ua rau txo qis system backpressure. Qhov no ua rau cov neeg khiav dej num ntau dua, lub sijhawm ua haujlwm luv dua, thiab txhim kho kab ke kev ua neej.
Zoo heev UV Transparency
Acetonitrile muaj qhov tsis tshua muaj UV absorbance, txhawb kev tshawb nrhiav pom hauv UV-HPLC thiab txhim kho lub hauv paus ruaj khov. Nws yog qhov zoo tagnrho rau kev taug qab- theem kev tshuaj ntsuam thiab kev tswj xyuas qhov zoo.
Muaj zog Compatibility
ACN yog tag nrho miscible nrog dej thiab feem ntau siv buffers, ua kom nws zoo - haum rau gradient HPLC txoj kev. Nws kuj tau sib xws nrog LC-MS, xa cov ionization huv thiab txhim khu kev qha.
Xaus
Ua tsaug rau nws qhov kev ua tau zoo sib luag hauv kev sib cais kev ua haujlwm, kev paub txog kev nkag siab, thiab kev sib raug zoo, acetonitrile (75-05-8) tseem yog qhov nyiam chromatography hnyav rau HPLC daim ntawv thov thoob ntiaj teb.
Vim li cas thiaj xaiv Gneebio ua koj tus neeg muag khoom?
Raws li ib tugAcetonitrile (CAS 75-05-8) Chaw tsim tshuaj paus, Gneebio tsom rau cov khoom sib xws, kev siv tau zoo, thiab kev ntseeg siab ntawm cov khoom siv ntau. Lub tuam txhab ua haujlwm raws li kev tswj hwm nruj nruj kom ntseeg tau tias Acetonitrile (CAS 75-05-8) ua tau raws li qhov yuav tsum tau muaj ntawm thaj chaw tsim khoom loj thiab tsis tu ncua.
Qhov tseem ceeb ntawm kev tsim khoom thiab khoom siv zog muaj xws li:
- Tswj purity qib tsim nyog rau kev lag luam thiab khoom siv
- ruaj khov batch-rau-batch zoo rau ntev- kev yuav khoom
- Muaj peev xwm muab tau los txhawb kev cog lus thiab chaw xaj khoom
- Export -npaj ntim thiab cov ntaub ntawv (COA, SDS, thiab lwm yam)
