Chromatography Yamadzimadzi Yogwira Ntchito Kwambiri (HPLC) ya Propionic Acid
Chida chachikulu cha njira iyi ndi chromatograph yamadzimadzi yogwira ntchito kwambiri. Chidacho chiyeneranso kuyesedwa, ndipo gawo loyenera ndi gawo loyenda limasankhidwa. Kuti mupeze propionic acid, gawo lozungulira la C18 limagwiritsidwa ntchito nthawi zambiri. Gawo loyenda nthawi zambiri limakhala losakaniza madzi ndi organic solvent (monga methanol) mu gawo lokhazikika, ndi mchere woyenera wa buffer (monga, potassium dihydrogen phosphate) wowonjezeredwa kuti asinthe pH ndikuwonetsetsa kuti pali kusiyana kwabwino. Potengera kuzindikira propionic acid mu zodzoladzola mwachitsanzo, chitsanzo chokongoletsera choyamba chimakonzedwa kale (monga, kuchepetsedwa, kusefedwa) kuti chichotse zonyansa zomwe zingasokoneze kupezeka. Chitsanzo chokonzedwacho chimalowetsedwa mu chromatograph yamadzimadzi yogwira ntchito kwambiri. Panthawi yogwira ntchito, gawo loyenda limanyamula chitsanzocho kudzera mu gawolo, komwe propionic acid imalekanitsidwa ndi zigawo zina kudzera mu kugawa kambiri pakati pa magawo osakhazikika ndi oyenda. Chowunikira cha UV-Vis chingagwiritsidwe ntchito, popeza propionic acid imayamwa kuwala pa mafunde enaake. Poyesa kuyamwa kwa propionic acid pa mafunde enaake ndikuyerekeza ndi curve yokhazikika, kuchuluka kwa propionic acid mu chitsanzocho kumatha kudziwika. Mzere wokhazikika umapangidwa pofufuza njira zingapo zodziwika bwino za propionic acid, zomwe zimakhala ndi kuchuluka kwa x-axis ndi kuyamwa kwa y-axis.

Shandong Pulisi Chemical Propionic Acid - Kuyera Kwambiri & Kupereka Kodalirika     info@pulisichem.cn
Shandong Pulisi Chemical Co., Ltd. imadzitamandira ndi propionic acid yapamwamba kwambiri (CAS 79-09-4, ≥99.5% purity), asidi wa carboxylic wokhala ndi unyolo wosinthasintha wokhala ndi mphamvu zokhazikika za mankhwala komanso magwiridwe antchito okhazikika. Propionic acid yathu ndi madzi omveka bwino, opanda mtundu, opangidwa motsatira miyezo yokhwima ya ISO kuti atsimikizire kuti palibe kuipitsidwa komanso kuti imagwirizana bwino ndi mafakitale.
Imagwiritsidwa ntchito kwambiri ngati chosungira chapamwamba kwambiri, choletsa nkhungu, komanso chophatikiza mankhwala, imagwira bwino ntchito yosungira chakudya cha ziweto ndi tirigu, zowonjezera chakudya, kupanga mankhwala, kupanga mankhwala ophera tizilombo, komanso kupanga mapulasitiki apulasitiki. Ndi kukana dzimbiri kwamphamvu komanso khalidwe lodalirika, malonda athu amakwaniritsa zosowa zosiyanasiyana zamafakitale pomwe amathandizira njira zopangira zotetezeka komanso zogwira mtima.
Timapereka njira zosinthira zolongedza: 200kg pulasitiki ng'oma, 1000kg IBC thanki, ndi ISO thanki, kuonetsetsa kuti mayendedwe otetezeka komanso zinthu zotsika mtengo zimaperekedwa kwa makasitomala apadziko lonse lapansi. Monga ogulitsa mankhwala odalirika aku China, timatsatira malamulo okhwima okhudza khalidwe, timapereka chithandizo chaukadaulo, komanso timapereka unyolo wokhazikika wogulira zinthu kuti bizinesi yanu ikule.
