I-High-Performance Liquid Chromatography (HPLC) yePropionic Acid
Isixhobo esiphambili sale ndlela yi-chromatograph yolwelo esebenza kakhulu. Esi sixhobo kufuneka silinganiswe, kukhethwe ikholamu efanelekileyo kunye nesigaba esihambayo. Ukufumanisa i-propionic acid, kusetyenziswa ikholamu yesigaba esibuyela umva se-C18. Isigaba esihambayo sidla ngokuba ngumxube wamanzi kunye nesinyibilikisi se-organic (esifana ne-methanol) kwinxalenye emiselweyo, kunye netyuwa efanelekileyo ye-buffer (umz., i-potassium dihydrogen phosphate) eyongeziweyo ukulungisa i-pH nokuqinisekisa ukwahlukana okuhle. Ukuthatha umzekelo wokuchongwa kwe-propionic acid kwi-cosmetics, isampuli ye-cosmetic iqale iphathwe kwangaphambili (umz., ixutywe, ihluzwe) ukususa ukungcola okunokuphazamisa ukuchongwa. Isampuli ephathwayo emva koko ifakwe kwi-chromatograph yolwelo esebenza kakhulu. Ngexesha lokusebenza, isigaba esihambayo sithwala isampuli ngekholamu, apho i-propionic acid yahlulwe kwezinye izinto ngokwahlulahlula phakathi kwezigaba ezimileyo nezihambayo. Isixhobo sokubona i-UV-Vis singasetyenziswa, njengoko i-propionic acid ifunxa ukukhanya kwii-wavelengths ezithile. Ngokulinganisa ukufunxwa kwe-propionic acid kwi-wavelength ethile kunye nokuyithelekisa ne-standard curve, umxholo we-propionic acid kwisampuli unokufunyanwa. I-standard curve yakhiwe ngokuhlalutya uthotho lwezisombululo ze-propionic acid ezisemgangathweni zamanqanaba aziwayo, kunye noxinzelelo kwi-x-axis kunye nokufunxwa kwi-y-axis.

I-Shandong Pulisi Chemical Propionic Acid – Ubumsulwa Obuphezulu kunye nobonelelo oluthembekileyo     info@pulisichem.cn
I-Shandong Pulisi Chemical Co., Ltd. ibonelela nge-propionic acid ekumgangatho ophezulu (CAS 79-09-4, ≥99.5% ubumsulwa), i-carboxylic acid eguquguqukayo eneempawu zeekhemikhali ezizinzileyo kunye nokusebenza okuzinzileyo. I-propionic acid yethu lulwelo olucacileyo, olungenambala, olwenziwe phantsi kwemigangatho engqongqo ye-ISO ukuqinisekisa ukungcola okuphantsi kunye nokuhambelana okuphezulu kuzo zonke izicelo zoshishino.
Isetyenziswa kakhulu njengesigcini esikumgangatho ophezulu, isithinteli sokungunda, kunye nesiphakathi seekhemikhali, igqwesile ekugcinweni kokutya kwezilwanyana kunye neenkozo, izongezo zokutya, ukwenziwa kwamayeza, imveliso yezibulali-zinambuzane, kunye nemveliso yeplastiki. Ngokumelana nokugqwala okunamandla kunye nomgangatho othembekileyo, imveliso yethu iyahlangabezana neemfuno ezahlukeneyo zoshishino ngelixa ixhasa iinkqubo zemveliso ezikhuselekileyo nezisebenzayo.
Sinikezela ngeendlela zokupakisha eziguquguqukayo: iidrama zeplastiki ezingama-200kg, iitanki ze-IBC ezingama-1000kg, kunye neetanki ze-ISO, ukuqinisekisa ukuthuthwa okukhuselekileyo kunye nokuhanjiswa kwempahla okungabizi kakhulu kubathengi behlabathi. Njengomthengisi weekhemikhali othembekileyo waseTshayina, sinamathela kulawulo oluqinileyo lomgangatho, sinikezela ngenkxaso yobuchwephesha, kwaye sinikezela ngemixokelelwane yokubonelela ezinzileyo ukuqhuba ukukhula kweshishini lakho.
