Hoʻohana mākou i nā kuki e hoʻomaikaʻi i kou ʻike. Ma ka hoʻomau ʻana e nānā i kēia pūnaewele, ʻae ʻoe i kā mākou hoʻohana ʻana i nā kuki. ʻIke hou aku.
Hāʻawi i ka nānā mau ʻana o ka acetonitrile (ACN): nā gradients pae mobile wai i hoʻohana ʻia i ka hoʻokaʻawale chromatographic hoʻomākaukau pae hoʻohuli o nā mea hana lāʻau lapaʻau me ka hoʻohana ʻana i kahi photometer kānana ClearView db fiber optic.
E hoʻohana i ka spectrophotometer e ana i ka spectrum NIR o ka hui ʻana o ka ACN:wai, koho i ka nalu no ka photometer kaʻina hana Process Insights. Ua ana ʻia nā laʻana ma nā cuvettes quartz 10 mm ma 40 a me 50°C me ka hoʻohana ʻana i kahi kaula fiber optic OH haʻahaʻa 2 m.
Ma ke kiʻi 1 e hōʻike ana i nā spectra i loaʻa no nā ʻāpana nuipa 10, 20, 30, 40 a me 50. % wai i loko o ka acetonitrile. ʻO ka piko wai nui ma kahi o 1420 nm ma waho o ke ala optical i koho ʻia he 10 mm. ʻO kekahi koho ʻē aʻe, ʻo ia ka hoʻohana ʻana i kahi ala optical 1 a i ʻole 2 mm e mālama i kēia piko ma ka unahi. He ʻokoʻa iki nā piʻo no kēlā me kēia ʻano, e hōʻike ana i ka hopena o ka mahana o ka laʻana ma ka spectrum wai.
E koho i ʻelua mau nalu no ka hoʻoponopono ʻana. Hoʻokomo pū ka kumu hoʻohālike hoʻoponopono i kahi coefficient no ka mahana o ka laʻana. Ma ke kiʻi 2 e hōʻike ana i kahi pakuhi o nā hopena i wānana ʻia a me nā hopena maoli, a hōʻike i kahi calibration maikaʻi loa me R2 o 0.9997 a me ka hewa maʻamau o 0.3% wai. ʻO nā coefficient mahana he hoʻoponopono o 0.15% wai/°C. No laila, hāʻawi ʻo ClearView db i ka pololei maikaʻi loa me ka drift lōʻihi ma lalo o 500 µA.
Hoʻomaʻalahi ka ClearView db photometer haʻahaʻa haʻahaʻa o Process Insights i kēia ana ma ka hoʻohana ʻana i kahi cell kahe e hoʻopili pololei ana i ka probe fiber optic a i ʻole e kāpae i ke kahe. Hiki i ka ClearView db photometer mai Process Insights ke ana i ʻelua mau sensor fiber optic kūʻokoʻa i ka manawa like, e hoʻemi ana i ka huina kumukūʻai o ke kiko laʻana.
Ua loaʻa kēia ʻike, ua hōʻoia ʻia a ua hoʻololi ʻia mai nā mea i hāʻawi ʻia e Process Insights - Optical Absorbment Spectroscopy.
No ka ʻike hou aku e pili ana i kēia kumu, e kipa i ka pūnaewele Process Insights - Optical Absorbment Spectroscopy.

Ma kēia hālāwai ninaninau, kamaʻilio ʻo AZoM me Brandon Van Leer, Luna Hoʻokele Kūʻai Huahana Kiʻekiʻe, a me Eric Görgen, Luna Hoʻokele Kūʻai Huahana Kiʻekiʻe, Thermo Fisher Scientific, e pili ana i ka ʻōnaehana kukuna ion broadband CleanMill hou. Kūkākūkā lākou i nā noi a me ka hoʻoikaika ma hope o ka hoʻokumu ʻia ʻana o ka huahana.
Ma mua o ka hālāwai kūkā ʻo Battery Electric Vehicle Architectures USA i Iune, ua ninaninau ʻo AZoM iā H. Yigit Cem Altintas o Ford Otosan e pili ana i ka mōʻaukala o ka hui a pehea e ulu ai e hoʻokō i nā pilikia hou o ka hoʻololi ʻana i ka uila o nā kaʻa.
Ma kēia hālāwai ninaninau, kamaʻilio ʻo AZoM me ka Luna Hoʻokele Huahana ʻo Avantes ʻo Ger Loop a me ka Luna Hoʻokele Hana ʻo Edwin Sportel e pili ana i kā lākou spectrometer photon AvaSpec-Pacto ikaika hou.
He spectrometer nuipa lawe lima ʻo MiDas™ e hoʻohui pono ʻia me nā huahana ʻē aʻe o ka moʻo MiD e hoʻonui i ka hana lab.
He spectrometer photonic hou ikaika ʻo AvaSpec-Pacto i hoʻolālā ʻia e Avantes e kūlike me nā ʻano noi like ʻole.
Ua lako pono ka X100-FTA hou mai Testometric no ka ʻoihana hoʻāʻo meaʻai a me ke ʻano me kahi ʻōnaehana hoʻāʻo kikohoʻe piha me ka pololei a me ke kiʻekiʻe.
