Kev Siv Tshuaj Chromatography Ua Haujlwm Zoo (HPLC) ntawm Propionic Acid
Lub cuab yeej tseem ceeb rau txoj kev no yog cov kua chromatograph ua haujlwm siab. Cov cuab yeej no kuj yuav tsum tau calibrated, nrog rau ib kem thiab theem mobile uas tsim nyog xaiv. Rau kev ntes propionic acid, C18 reversed-phase column feem ntau siv. Lub theem mobile feem ntau yog sib tov dej thiab cov organic solvent (xws li methanol) hauv ib qho piv txwv ruaj khov, nrog rau cov ntsev buffer tsim nyog (piv txwv li, potassium dihydrogen phosphate) ntxiv rau kom kho pH thiab xyuas kom meej tias muaj kev sib cais zoo. Piv txwv li, kev ntes propionic acid hauv cov tshuaj pleev ib ce, cov qauv tshuaj pleev ib ce raug kho ua ntej (piv txwv li, diluted, lim) kom tshem tawm cov khoom tsis huv uas yuav cuam tshuam rau kev ntes. Cov qauv kho tom qab ntawd raug txhaj rau hauv cov kua chromatograph ua haujlwm siab. Thaum lub sijhawm ua haujlwm, theem mobile nqa cov qauv los ntawm kem, qhov twg propionic acid raug cais tawm ntawm lwm cov khoom los ntawm ntau qhov kev faib ntawm cov theem ruaj khov thiab cov theem mobile. Lub tshuab ntes UV-Vis tuaj yeem siv, vim propionic acid nqus lub teeb ntawm cov wavelengths tshwj xeeb. Los ntawm kev ntsuas qhov absorbance ntawm propionic acid ntawm cov wavelength tshwj xeeb thiab piv rau nws nrog tus qauv nkhaus, cov ntsiab lus propionic acid hauv cov qauv tuaj yeem txiav txim siab. Tus qauv nkhaus yog tsim los ntawm kev tshuaj xyuas cov txheej txheem ntawm propionic acid cov tshuaj txheem ntawm cov concentration paub, nrog rau qhov concentration ntawm x-axis thiab absorbance ntawm y-axis.
