Koʻikoʻi o ka analytical integrity ho'āʻo onā kānana syringe

He mea koʻikoʻi ka hoʻomaʻemaʻe ʻana i ka hana, no laila he mea nui ka hoʻāʻo pono ʻana o ka kānana syringe, a aia kona koʻikoʻi i:

1. E hōʻoia i ka nui filtration pore nui o ka membrane

2. E nānā inā ua hoʻopili maikaʻi ʻia ka kānana

3. ʻIke i ka pōʻino

4. E hōʻoia i ka hoʻokomo pono

5. E hōʻoia e hoʻokō ka ʻōnaehana kānana i ka hana hōʻoia

ʻO ka hoʻāʻo pono ʻana kā mākou hōʻoia huahana a me ka mana o ka maikaʻi o ka hana, ʻo ia ke kaʻina hana maʻamau o ka hui

He aha ka hana o kakānana syringe

Hāʻawi i kahi kānana syringe hoʻokaʻawale e hui pū i ka membrane cellulose, nylon membrane, PVDF membrane o polyvinylidene fluoride e hoʻokō i nā koi like ʻole o nā mea hoʻohana no ka nui o ka laʻana kānana a me ka hoʻohālikelike kemika.

Hoʻohana ka kānana syringe organik i ka PTFE (polytetrafluoroethylene) microporous membrane, nona ka hoʻohālikelike kemika maikaʻi. Loaʻa iā ia ke kūpaʻa kemika maikaʻi loa i nā hopena kūlohelohe HPLC maʻamau e like me ka methanol, acetonitrile, n-hexane, isopropanol, etc. Soluble. Hiki ke hoʻohana ʻia e kānana i nā mea hoʻoheheʻe organik.

Hoʻohana ka kānana syringe wai / wai i kahi membrane microporous polyethersulfone (PES). Hoʻohana ʻia ia no ka kānana ʻana i nā laʻana hoʻonā wai, ʻaʻole kūpono no ke kānana ʻana i nā mea hoʻoheheʻe organik. ʻO ka kānana syringe hiki ke hoʻokuʻu ʻia e hiki ke kānana wikiwiki a me ka maikaʻi.

ʻO ka hana kānana syringe: kūpono no ka ʻōnaehana wai a me nā mea hoʻoheheʻe organik like ʻole, kūpaʻa i nā solvents a pau, haʻahaʻa haʻahaʻa. Loaʻa iā ia nā hiʻohiʻona o ka ea permeability a me ka wai impermeability, ka nui o ka ea flux, ke kiʻekiʻe o ka paʻa ʻana o ka ʻāpana, ke kūpaʻa wela maikaʻi, ke kūʻē ʻana i nā waikawa ikaika, alkalis, nā mea hoʻoheheʻe a me nā mea hoʻoheheʻe, kūʻē i ka wā kahiko, non-stickiness, non-flammability, non- ʻona, a me ka biocompatibility. Hoʻohana nui ʻia kāna mau huahana pili i ka kemika, lāʻau lapaʻau, palekana kaiapuni, uila, meaʻai, ikehu a me nā māla ʻē aʻe.

He aha ke kumu o kakānana syringe

ʻO ka kānana syringe kahi mea kānana wikiwiki, kūpono a hilinaʻi hoʻi i hoʻohana mau ʻia i nā laboratories. He nani kona helehelena, ke kaumaha māmā a me ka maʻemaʻe kiʻekiʻe. Hoʻohana nui ʻia ia no ka prefiltration laʻana, ka wehewehe a me ka wehe ʻana i nā ʻāpana, a me ka sterilization a me ka kānana o nā wai a me nā kinoea. ʻO ia keʻano i makemakeʻia no ka kānanaʻana i nā mea liʻiliʻi o HPLC a me GC. E like me keʻano o ka sterilization, hiki ke hoʻokaʻawaleʻia i ka sterilization a me ka non-sterilization. Na ka mea hoʻoponopono aʻe e hoʻolauna iā ʻoe i ke kumu o ka kānana syringe:

1. Ka wehe ʻana i nā waihona protein a me ka hoʻoholo hoʻoheheʻe

2. Ka hoʻāʻo ʻana i ka inu a me ka ʻai a me ka nānā ʻana i ka biofuel

3. Laʻana pretreatment

4. Ka nānā 'ana a me ka nānā 'ana i ke kaiapuni

5. Ka nānā 'ana i nā lā'au lapa'au a me nā huahana wai maoli

6. Liquid kinoea chromatography laʻana hoʻomākaukau a me ka kiko'ī QC kālailai

7. ʻO ka kānana kinoea a me ka ʻike wai
