Acetonitrile Solvent rau HPLC:
High-Kev Ua Haujlwm Liquid Chromatography (HPLC): Qhov no yog daim ntawv thov loj tshaj plaws ntawmCAS 75-05-8 Acetonia. Vim nws tsis tshua muaj UV cutoff wavelength (~ 190nm), cov khoom hnyav hnyav, thiab cov polarity tsim nyog, nws yog ib qho ntawm cov theem mobile nyiam rau HPLC tsom xam.
Qhov zoo
- Siab polarity: Acetonitrile hnyav tuaj yeem yaj ntau yam kev ntsuas, los ntawm cov polar mus rau nruab nrab tsis yog -polar.
- Miscibility nrog dej: Nws tso cai rau kev tsim cov theem ntawm lub xov tooj ntawm tes nrog qhov sib txawv ntawm qhov muaj zog, ua kom zoo -tuning ntawm kev sib cais.
- Tsawg viscosity: Nws ntws yooj yim los ntawm kem, ua kom muaj kev sib cais zoo.
- Tsis tshua muaj UV absorbance: CAS 75-05-8 Acetonitrile txo kev cuam tshuam nrog UV tshawb pom, tso cai rau kev soj ntsuam rhiab ntawm cov tshuaj ntsuam xyuas.
