Sisebenzisa amakhukhi ukuthuthukisa ulwazi lwakho. Ngokuqhubeka uphequlula le sayithi, uyavuma ukusebenzisa kwethu amakhukhi. Ulwazi olwengeziwe.
Ihlinzeka ngokuqapha okuqhubekayo kwe-acetonitrile (ACN): ama-gradients esigaba esihambayo samanzi asetshenziswa ekuhlukaniseni i-chromatographic yokulungiselela isigaba esingemuva kwezithako ezisebenzayo zemithi kusetshenziswa i-ClearView db fiber optic filter photometer.
Sebenzisa i-spectrophotometer ukukala i-NIR spectrum yengxube yamanzi ye-ACN:, khetha ubude be-wavelength ye-Process Insights process photometer. Amasampula alinganiswe kuma-cuvettes e-quartz angu-10 mm ku-40 no-50°C kusetshenziswa ikhebula le-fiber optic le-OH eliphansi elingamamitha angu-2.
Ku-Fig. 1 kukhombisa ama-spectra atholiwe ezingxenyeni ezingu-10, 20, 30, 40 kanye no-50 zobunzima. % wamanzi ku-acetonitrile. I-water peak eyinhloko ezungeze i-1420 nm ingaphandle kobude bendlela ekhethiwe ye-optical engu-10 mm. Enye indlela ukusebenzisa indlela ye-optical engu-1 noma engu-2 mm ukugcina le peak isezingeni. Ama-curve ahlukile kancane ku-concentration ngayinye, okubonisa umphumela wokushisa kwesampula ku-water spectrum.
Khetha ama-wavelength amabili okulinganisa. Imodeli yokulinganisa ihlanganisa ne-coefficient yezinga lokushisa lesampula. Ku-fig. 2 ikhombisa igrafu yemiphumela ebikezelwe neyangempela, futhi ikhombisa ukulinganisa okuhle kakhulu nge-R2 ka-0.9997 kanye nephutha elijwayelekile lamanzi angu-0.3%. Ama-coefficient okushisa alungiswa ngamanzi angu-0.15%/°C. Ngakho-ke, i-ClearView db inikeza ukunemba okuhle kakhulu ngokuzulazula kwesikhathi eside okungaphansi kuka-500 µA.
I-ClearView db photometer eshibhile ye-Process Insights yenza kube lula lokhu kulinganisa ngokusebenzisa iseli lokugeleza elixhuma ngqo ku-probe ye-fiber optic noma elidlula ukugeleza. I-ClearView db photometer evela ku-Process Insights ingalinganisa izinzwa ezimbili ezizimele ze-fiber optic ngesikhathi esisodwa, inciphise izindleko eziphelele zephuzu lokuhlola.
Lolu lwazi lutholakale, lwaqinisekiswa futhi lwaguqulwa kusukela ezintweni ezinikezwe yi-Process Insights – Optical Absorbment Spectroscopy.

Ukuqonda Kwenqubo – i-spectroscopy yokumuncwa kwe-optical. 2023. Ukuqapha okuqhubekayo kwe-acetonitrile kwezicelo zemithi. I-AZoM, ifinyelelwe ngomhlaka-20 Juni 2023, https://www.azom.com/article.aspx?ArticleID=16661.
Kule ngxoxo, i-AZoM ixoxa noBrandon Van Leer, uMphathi Omkhulu Wokumaketha Komkhiqizo, kanye no-Eric Görgen, uMphathi Omkhulu Wokumaketha Komkhiqizo, i-Thermo Fisher Scientific, mayelana nohlelo olusha lwe-CleanMill broadband ion beam. Baxoxa ngezinhlelo zokusebenza kanye nokuphefumulelwa ngemuva kokudalwa komkhiqizo.
Ngaphambi kwengqungquthela kaJuni Battery Electric Vehicle Architectures USA, i-AZoM ixoxisane no-H. Yigit Cem Altintas weFord Otosan ngomlando wale nkampani nokuthi izothuthuka kanjani ukuze ibhekane nezinselele ezintsha zokushintshela ekufakweni kukagesi ezimotweni.
Kule ngxoxo, i-AZoM ixoxa noMphathi Womkhiqizo we-Avantes uGer Loop kanye noMphathi Wokukhiqiza u-Edwin Sportel mayelana ne-spectrometer yabo entsha enamandla ye-AvaSpec-Pacto photon.
I-MiDas™ iyi-spectrometer ephathekayo ehlangana kalula neminye imikhiqizo ochungechungeni lwe-MiD ukuze kwandiswe umkhiqizo webhubhu.
I-AvaSpec-Pacto iyi-spectrometer entsha enamandla ye-photonic eklanywe yi-Avantes ukuze ihambisane nezinhlelo zokusebenza eziningi ezahlukene.
I-X100-FTA entsha evela ku-Testometric yemboni yokuhlola ukudla nokuthungwa ifakwe uhlelo lokuhlola lwedijithali oluphelele olunokunemba okuphezulu nokunemba.
