Nā Hana no ka ʻIke ʻana i ka Waikawa Propionic
Ka Chromatography Kinoea ʻAkika Propionic (GC)
He ʻano hana maʻamau a kūpono hoʻi kēia no ka ʻike ʻana i ka waikawa propionic. ʻO ka mea mua, e hōʻoia i ka hoʻoponopono pono ʻia ʻana o ka chromatograph gas me nā palena kūpono. E hoʻohana i kahi kolamu kūpono, e like me ke kolamu capillary, kahi e hāʻawi ai i ka hoʻokaʻawale maikaʻi no ka waikawa propionic. Ma ka lawe ʻana i ka nānā ʻana o ka waikawa propionic i ka meaʻai ma ke ʻano he laʻana, ua hoʻokomo ʻia ka hāpana meaʻai i mālama mua ʻia i loko o ka puka komo chromatograph gas. Hoʻoheheʻe ʻia ka hāpana i loko o ke awa hoʻokomo a lawe ʻia e kahi kinoea lawe maʻemaʻe kiʻekiʻe (ʻo ka nitrogen maʻamau) i loko o ke kolamu. He mea nui ke kinoea lawe maʻemaʻe kiʻekiʻe no ka pololei o ka ʻike ʻana. I loko o ke kolamu, ua hoʻokaʻawale ʻia ka waikawa propionic mai nā haumia ʻē aʻe ma muli o nā ʻokoʻa o kā lākou mau coefficients mahele ma waena o nā pae paʻa a me nā pae neʻe. Hoʻokaʻawale nā ​​​​hui like ʻole mai ke kolamu i nā manawa like ʻole a hiki i ka mea ʻike. ʻO kahi mea ʻike maʻamau i hoʻohana ʻia ʻo ia ka mea ʻike ionization lapalapa (FID), kahi mea koʻikoʻi loa i nā hui organik i loaʻa ke kalapona. Ke hiki ka waikawa propionic i ka mea ʻike, hana ia i kahi hōʻailona uila e like me kona ʻano. Ma ka hoʻohālikelike ʻana i ka chromatogram hopena me ko ka chromatogram o kahi ʻike ʻia o ka maʻamau propionic acid i kālailai ʻia ma lalo o nā kūlana like, hiki ke helu pololei ʻia ka nui o ka propionic acid i loko o ka hāpana ma muli o ka ʻāpana piko a i ʻole ke kiʻekiʻe o ka piko.

ʻO Shandong Pulisi Chemical Co., Ltd. kahi mea hana hilinaʻi a me ka mea hoʻolako o ka waikawa propionic kiʻekiʻe, e hāʻawi ana i nā māka kūlike i hana ʻia no nā ʻāpana meaʻai, lāʻau lapaʻau, ʻoihana a me ka mahiʻai. Hana ʻia kā mākou waikawa propionic ma lalo o nā kūlana kaohi maikaʻi koʻikoʻi, e hōʻoiaʻiʻo ana i ka maʻemaʻe kiʻekiʻe, ka hana paʻa a me ka lako hilinaʻi no nā mea kūʻai aku honua. Hoʻohana nui ʻia ma ke ʻano he mea mālama, mea hoʻoponopono pH, a me ka waena kemika, hoʻokō kā mākou waikawa propionic i nā kikoʻī honua a kākoʻo i nā noi like ʻole mai ka mālama ʻana i ka meaʻai a hiki i ka synthesis organik. Hāʻawi mākou i ka hoʻopili maʻalahi, nā kumukūʻai hoʻokūkū, a me ke kākoʻo loea i hoʻolaʻa ʻia e hoʻokō i nā pono o nā mea kūʻai aku like ʻole.info@pulisichem.cn
