CONTROS HydroFIA® TA
TA – ANALYZER NO KA HUI ALKALINI MA KA WAI
ʻO ka nui o ka alkalinity he mea hoʻohālikelike koʻikoʻi no nā ʻano ʻepekema o ka noi ʻana me ka noiʻi ʻana i ka moana a me ka noiʻi kemika carbonate, ka nānā ʻana i nā kaʻina biogeochemical, ka moʻomeheu aqua / mahiʻai iʻa a me ka nānā ʻana i ka wai pore.
KUMU HANA
ʻO ka nui o ka wai kai i ʻakika ʻia e ka hoʻokomo ʻia ʻana o ka nui o ka waika hydrochloric (HCl).
Ma hope o ka acidification, ua wehe ʻia ka CO₂ i hana ʻia i loko o ka laʻana ma o kahi ʻāpana degassing e pili ana i ka membrane e hopena i kahi i kapa ʻia ʻo wehe-cell titration. Hoʻoholo ʻia ka hoʻoholo ʻana o ka pH ma hope o kahi mea hoʻonaninani hōʻailona (Bromocresol green) a me VIS absorption spectrometry.
Me ka paʻakai a me ka mahana, hoʻohana pololei ʻia ka hopena pH no ka helu ʻana i ka nui o ka alkalinity.
HIʻona
- Nā pōʻaiapuni ana ma lalo o 10 min
- Hoʻoholo pH ikaika me ka hoʻohana ʻana i ka spectrometry absorption
- titration helu hoʻokahi
- Hoʻohana haʻahaʻa haʻahaʻa (<50 ml)
- Hoʻohana haʻahaʻa reagent (100 μL)
- ʻO nā pahu pahu reagent "Plug and Play" pili i ka mea hoʻohana
- Hoʻemi ʻia nā hopena biofouling ma muli o ka acidification o ka hāpana
- Nā mea hoʻonoho kūʻokoʻa lōʻihi
NA KOHO
- Hoʻohui i loko o nā ʻōnaehana ana ma VOS
- Nā kānana hoʻoheheʻe keʻa no nā wai hoʻopiʻi kiʻekiʻe / sediment
