He aha te Whakatōtō Whakaari? He aha i "Uaua ai ki te Mahi"?
I roto i te tātari i ngā hua wāhanga hinu i roto i te umanga matū hinu, ko te tohatoha o te whānuitanga kohua he tohu matua mō te ine i te kounga o te hua me te ārahi i te whakahaere tukanga. Ahakoa he māmā noa ngā tikanga whakatō tuku iho, he roa te wā e pau ana, he nui te tauira e pau ana, ā, he ngoikore te whakahokinga, ā, kāore e ranea mō ngā hiahia tere kimihanga ahumahi o ēnei rā.
Nō reira, i puta mai te whakatōtōtanga whakatauira. Ko te paerewa NB/SH/T 0558-2016 a Haina e whakatakoto ana i ngā whakaritenga pakari mō ēnei tohu: mai i te pikinga o te awhe pāmahana teitei me te hoahoa pūwāhi makariri ki te nekehanga taketake ≤1% FS/h, ka whakamātautauhia e ia paearu te mahi pono o te taputapu. Me pēhea te whakatutuki a te BFRL SP-5220 i ēnei whakaritenga takitahi me te tino tika?
Te Kaupapa Tikanga
Kāore te tikanga whakahorohoro whakaata e ine tika mā te horahanga tihi chromatography takitahi, engari ka whakatū tuatahi i te taurite "wā pupuri-ira kohua", kātahi ka tapatapahia, ka kohikohia te chromatogram tauira i te tuaka wā. Ka hurihia te ōrau rere whakaemi ki te pāmahana e rite ana, ā, ka whiwhi i te tohatoha ara kohua o te tauira. He māmā noa iho, ka whakamahia te chromatography hei "whakataurite" i te tukanga whakahorohoro ā-tinana.
Heoi, he nui rawa ngā whakaritenga mō tēnei tikanga, arā, ko te taputapu:
1. Me pumau te pihi whakatikatika—mā te paku rerekētanga o te whanaungatanga i waenganui i te wā pupuri me te ira kohua ka puta he rerekētanga ki ngā hua o te ira whakatō.
2. Me haere tonu te tohutoro hinu tohutoro—mēnā he hē te pikinga, he hekenga o te tihi, he tauhohenga rerekē rānei, he tohu tēnei nō te hapa pūnaha.
3. Me whakapūmau ngā rauropi pūmanawa—me tino whai te whakaurunga poro, te hurihanga pāmahana, me te whakaurunga pūwāhi whakahoro i te paerewa NB/SH/T 0558.
Nō reira, me tutuki i te pūnaha whakatōtō whaihanga tino matatau ngā paerewa mō te whakahaere i te ara iahiko hau, te whakahaere pāmahana, te rārangi o te pūoko, me ngā rauropi pūmanawa. Kua hangaia te Beifen Ruilili SP-5220 mō tēnei kaupapa.

1)Te whanaungatanga whakatikatika i waenganui i te wā pupuri me te pūwāhi kohua
E ai ki te whakaaturanga i te Pikitia 1, ko te whanaungatanga whakatikatika i waenganui i te wā pupuri me te pūwāhi kohua, he tonu te pihi wā pupuri me te pūwāhi kohua i whakatūria i te pūwāhi paerewa o ngā Ortho alkanes, ā, he pai te monotonicity, e mahi ana hei pūtake mō te hurihanga pāmahana whakatōtō whakatauira.

Ka taea te whakamahi i te hononga tihi tohutoro me te chromatogram hinu tohutoro hei whakaū i te tūnga whakahaere o te tikanga. E whakaatu ana te chromatogram he hononga tautuhi tō te tūranga tihi tohutoro ki te tohatoha tauira, ā, e whakaatu ana te hinu tohutoro i tētahi āhuatanga tohatoha tonu puta noa i te awhe kohua katoa.
