ʻO ka Chromatography Wai Hana Kiʻekiʻe (HPLC) o ka Waikawa Propionic
ʻO ka mea hana koʻikoʻi no kēia ʻano hana, ʻo ia ka chromatograph wai hana kiʻekiʻe. Pono hoʻi e hoʻoponopono ʻia ka mea hana, me kahi kolamu kūpono a me ka pae mobile i koho ʻia. No ka ʻike ʻana i ka waikawa propionic, hoʻohana pinepine ʻia kahi kolamu C18 reversed-phase. ʻO ka pae mobile he hui maʻamau o ka wai a me kahi mea hoʻoheheʻe organik (e like me ka methanol) ma kahi ʻāpana paʻa, me kahi paʻakai buffer kūpono (e laʻa, potassium dihydrogen phosphate) i hoʻohui ʻia e hoʻoponopono i ka pH a hōʻoia i ka hoʻokaʻawale maikaʻi. Ma ka lawe ʻana i ka ʻike ʻana o ka waikawa propionic i nā mea hoʻonani ma ke ʻano he laʻana, ua mālama mua ʻia ka laʻana hoʻonani (e laʻa, diluted, kānana) e wehe i nā haumia e hoʻopilikia paha i ka ʻike ʻana. A laila hoʻokomo ʻia ka laʻana i mālama ʻia i loko o ka chromatograph wai hana kiʻekiʻe. I ka wā o ka hana, lawe ka pae mobile i ka laʻana ma o ke kolamu, kahi e hoʻokaʻawale ʻia ai ka waikawa propionic mai nā ʻāpana ʻē aʻe ma o ka hoʻokaʻawale ʻana ma waena o nā pae paʻa a me nā pae mobile. Hiki ke hoʻohana ʻia kahi mea ʻike UV-Vis, ʻoiai ʻo ka waikawa propionic e omo i ka mālamalama ma nā nalu kikoʻī. Ma ke ana ʻana i ka absorbance o ka waikawa propionic ma ka nalu kikoʻī a me ka hoʻohālikelike ʻana me kahi piʻo maʻamau, hiki ke hoʻoholo ʻia ka nui o ka waikawa propionic i loko o ka laʻana. Kūkulu ʻia ke kiʻikuhi maʻamau ma ke kālailai ʻana i kahi moʻo o nā hopena maʻamau o ka waikawa propionic o nā ʻano i ʻike ʻia, me ka ʻano ma ka axis-x a me ka absorbance ma ka axis-y.

ʻO Shandong Pulisi Chemical Propionic Acid - Hoʻomaʻemaʻe kiʻekiʻe a me ka lako hilinaʻi     info@pulisichem.cn
Hāʻawi haʻaheo ʻo Shandong Pulisi Chemical Co., Ltd. i ka waikawa propionic kiʻekiʻe (CAS 79-09-4, ≥99.5% maʻemaʻe), kahi waikawa carboxylic kaulahao pōkole me nā waiwai kemika paʻa a me ka hana mau. ʻO kā mākou waikawa propionic he wai moakaka, kala ʻole, i hana ʻia ma lalo o nā kūlana ISO koʻikoʻi e hōʻoia i ka haumia haʻahaʻa a me ke kūlike kiʻekiʻe ma nā noi ʻoihana.
Hoʻohana nui ʻia ma ke ʻano he mea mālama kiʻekiʻe, mea hoʻopale mold, a me ka waena kemika, ʻoi aku ka maikaʻi ma ka mālama ʻana i nā meaʻai holoholona a me nā palaoa, nā mea hoʻohui meaʻai, ka hana lāʻau lapaʻau, ka hana pesticide, a me ka hana plasticizer plastic. Me ke kūpaʻa ikaika i ka corrosion a me ka maikaʻi hilinaʻi, hoʻokō kā mākou huahana i nā koi ʻoihana like ʻole me ke kākoʻo ʻana i nā kaʻina hana palekana a maikaʻi.
Hāʻawi mākou i nā koho hoʻopili maʻalahi: nā pahu plastik 200kg, nā pahu IBC 1000kg, a me nā pahu ISO, e hōʻoiaʻiʻo ana i ka halihali palekana a me nā logistics kūpono no nā mea kūʻai aku honua. Ma ke ʻano he mea hoʻolako kemika Kina hilinaʻi, pili mākou i ka kaohi maikaʻi koʻikoʻi, hāʻawi i ke kākoʻo loea ʻoihana, a hāʻawi i nā kaulahao lako paʻa e hoʻokele i ka ulu ʻana o kāu ʻoihana.
