Kuonetsetsa kuti hydroxypropyl methylcellulose (hpmc) amaphatikizapo njira zoyeserera zolimbitsa thupi zosiyanasiyana. Nayi njira mwachidule kwa njira zina zoyeserera zomwe zimagwiritsidwa ntchito ndi opanga HPMC:
Kusanthula Kwa Zinthu:
Mayeso Odziwitsa: Opanga amagwiritsa ntchito njira ngati ftir (masinthidwe ailfforft afiritsed spectroscopy) ndi nmr (maglear magnetic resonance) kuti mutsimikizire zodziwika bwino.
Kuwunika kwa Kuyeretsa: Njira monga HPLC (High-Boor-Stand Frematography) imagwiritsidwa ntchito kuti mudziwe zoyera za zida zopangira, kuonetsetsa kuti amakwaniritsa miyezo yotsimikizika.
Kuyeserera kwa ntchito:
Mlingo wa IscCon: Masukini ndi gawo lovuta kwambiri kwa HPMC, ndipo limayesedwa pogwiritsa ntchito zodulidwa pamitundu yosiyanasiyana yopanga kusasinthika.
Kusanthula kwachinyezi: Chinyezi chogwiritsira ntchito chimakhudza katundu wa HPMC. Njira monga Karl Foischer imagwiritsidwa ntchito kuti adziwe chinyezi.
Kusanthula Kwa tinthu: Njira monga laser zimagwiritsidwa ntchito kuwonetsetsa kuti tinthu tambiri tagawikidwe kambiri, chomwe ndi chofunikira kwambiri.
Kuyesa Khalidwe Labwino:
Kusanthula kwa mankhwala: hpmc kumachitika kusanthula kwa mankhwala, zotsalira, ndipo zodetsa zina zimagwiritsa ntchito njira ngati GC-OES (Milp-OIDCOPPY).
Kuyeserera Kwathupi: Kuyesedwa Kuphatikizika ndi ufa woyenda, kapa kachulukidwe kambiri, komanso kuphatikizidwa kutsimikiziridwa kuti mikhalidwe ya HPMC imakumana ndi HPMC.
Kuyesa kwamagetsi: Kuyipitsa microbial ndi kuda nkhawa mu ppmcecrical-gired hpmc. Mayeso owonjezera ndi ma sectical chizindikiritso amachitika kuti awonetsetse chitetezo chambiri.
Kuyeserera kwa magwiridwe antchito:
Maphunziro omasulira mankhwala: Kuyesa kwamankhwala osokoneza bongo, kusungunuka kofana kumachitika kuti awone kumasulidwa kwa zosakaniza za ma hpmc.
Mapangidwe a mafilimu: hpmc nthawi zambiri amagwiritsidwa ntchito m'mafilimu, ndipo amayesa ngati mphamvu yayikulu imawunikira mawonekedwe a makanema.
Kuyesa kwa Stit:
Maphunziro okalamba: Kuyesa kwa bati kumaphatikizapo kuyika zitsanzo zosiyanasiyana za HPMC ku nkhawa zosiyanasiyana monga kutentha ndi chinyezi.
Muli ndi kuyesedwa umphumphu: kwa zinthu zowoneka bwino, kuyesedwa kwa umphumphu kumatsimikizira kuti zopezeka bwino za HPMC kuchokera ku chilengedwe.
Kutsatira lamulo:
Miyezo yamankhwala: Opanga amatsatira miyezo yamankhwala ngati USP (United States Farmacapea) ndi EP (EP (Ep (Ep)
Zolemba ndi kusunga zolemba: Zolemba mwatsatanetsatane zoyesedwa, zimabweretsa, komanso njira zoyenera zotsimikizika zimasungidwa kuwonetsa kutsata mfundo zovomerezeka ndi mfundo zovomerezeka.
Opanga amagwiritsa ntchito njira zambiri zoyesera kuwunikira zopangira, kuyezetsa, kuwunika kwa magwiritsidwe, komanso kuwongolera kwa ma hydroxypyulose zinthu. Protocol yoyesererayi ndiyofunikira kuti muchepetse kusasinthika ndi kukwaniritsa zofunikira zosiyanasiyana zamankhwala monga mankhwala, chakudya, zodzola komanso zomangamanga.
