Te Whakamātautau Wai Mahi-Teitei (HPLC) o te Waikawa Propionic
Ko te taputapu matua mō tēnei tikanga ko te chromatograph wai mahi-teitei. Me whakatikatika anō hoki te taputapu, me te whiriwhiri i tētahi pou me te wāhanga neke e tika ana. Mō te kimi waikawa propionic, he pou wāhanga-hurihuri C18 te mea e whakamahia whānuitia ana. Ko te wāhanga neke he ranunga wai me te whakarewa waro (pērā i te methanol) i roto i tētahi ōwehenga pumau, me te tote ārai tika (hei tauira, te pāhare pākawa dihydrogen phosphate) e tāpirihia ana hei whakatika i te pH me te whakarite kia pai te wehenga. Hei tauira, mā te kimi i te waikawa propionic i roto i ngā mea whakapaipai, ka tukatukahia tuatahitia te tauira whakapaipai (hei tauira, kua whakaranua, kua tātarihia) hei tango i ngā poke ka whakararuraru pea i te kimi. Kātahi ka werohia te tauira kua rongoatia ki roto i te chromatograph wai mahi-teitei. I te wā e mahi ana, ka haria e te wāhanga neke te tauira mā roto i te pou, ka wehea te waikawa propionic mai i ētahi atu wāhanga mā te wehewehe maha i waenga i ngā wāhanga tūmau me ngā wāhanga neke. Ka taea te whakamahi i tētahi taputapu kite UV-Vis, nā te mea ka mimiti te waikawa propionic i te mārama i ngā roangaru motuhake. Mā te ine i te mimiti o te waikawa propionic i te roangaru motuhake me te whakataurite ki tētahi pihi paerewa, ka taea te whakatau i te ihirangi waikawa propionic i roto i te tauira. Ka hangaia te kōpiko paerewa mā te tātari i tētahi raupapa o ngā otinga paerewa waikawa propionic o ngā kukū e mōhiotia ana, ko te kukū kei te tuaka-x me te mimiti kei te tuaka-y.

Waikawa Propionic Matū Shandong Pulisi – Teitei te Parakore me te Tuku Pono     info@pulisichem.cn
E whakahīhī ana a Shandong Pulisi Chemical Co., Ltd. ki te tuku i te waikawa propionic kounga teitei (CAS 79-09-4, ≥99.5% parakore), he waikawa carboxylic mekameka poto maha-mahi me ngā āhuatanga matū pumau me te mahi pumau. He wai mārama, kore tae, he wai pūngāwerewere tā mātou waikawa propionic, i hangaia i raro i ngā paerewa ISO tino pakari hei whakarite i te iti o te poke me te hototahi teitei puta noa i ngā tono ahumahi.
He whānuitia te whakamahinga hei matū tiaki kounga teitei, hei aukati pokepokea ai, hei takawaenga matū hoki, he tino pai ki te rokiroki kai kararehe me te witi, ki ngā tāpiringa kai, ki te hanga rongoā, ki te hanga patu pepeke, me te hanga kirihou whakarewa. Mā te ātete kaha ki te waikura me te kounga pono, ka tutuki i tā mātou hua ngā tono ahumahi maha, me te tautoko i ngā tukanga whakaputa haumaru me te whai hua.
Kei a mātou ngā kōwhiringa takai ngāwari: ngā pahu kirihou 200kg, ngā tāke IBC 1000kg, me ngā tāke ISO, kia haumaru ai te kawe me te utu tika mō ngā kiritaki o te ao. Hei kaiwhakarato matū Hainamana pono, ka piri mātou ki te mana whakahaere kounga tino pakari, ka whakarato tautoko hangarau ngaio, ka tuku mekameka tuku pumau hei akiaki i te tipu o tō pakihi.
