Sisebenzisa iikuki ukuphucula amava akho. Ngokuqhubeka ukhangela le sayithi, uyavuma ukuba sisebenzise iikuki. Ulwazi oluthe kratya.
Ibonelela ngokubeka esweni okuqhubekayo kwe-acetonitrile (ACN): ii-gradients ze-aqueous mobile phase ezisetyenziswa ekuhlukaniseni i-chromatographic ye-preparative phase preparative yezithako ezisebenzayo zamayeza kusetyenziswa i-ClearView db fiber optic filter photometer.
Sebenzisa i-spectrophotometer ukulinganisa i-NIR spectrum yomxube wamanzi we-ACN:, khetha ubude be-wavelength ye-Process Insights process photometer. Iisampulu zilinganiswe kwii-cuvettes ze-quartz eziyi-10 mm kuma-40 kunye nama-50°C kusetyenziswa intambo ye-fiber optic ye-OH ephantsi eyi-2 m.
Kumfanekiso 1 ubonisa ii-spectra ezifunyenweyo ze-10, 20, 30, 40 kunye ne-50 ubunzima beendawo. % yamanzi kwi-acetonitrile. Incochoyi yamanzi ephambili ejikeleze i-1420 nm ingaphandle kobude bendlela ye-optical ekhethiweyo ye-10 mm. Olunye ukhetho kukusebenzisa indlela ye-optical ye-1 okanye ye-2 mm ukugcina le ncochoyi ikwizinga. Ii-curves zahlukile kancinci kuxinzelelo ngalunye, zibonisa impembelelo yobushushu besampulu kwi-spectrum yamanzi.
Khetha ubude be-wavelengths ezimbini zokulinganisa. Imodeli yokulinganisa ikwabandakanya i-coefficient yobushushu besampulu. Kumfanekiso wesi-2 ibonisa igrafu yeziphumo eziqikelelweyo kunye nezokwenyani, kwaye ibonisa ukulinganisa okugqwesileyo nge-R2 ye-0.9997 kunye nempazamo eqhelekileyo yamanzi ayi-0.3%. Ii-coefficients zobushushu zilungiso lwamanzi ayi-0.15%/°C. Ke ngoko, i-ClearView db ibonelela ngokuchaneka okugqwesileyo ngokushukuma kwexesha elide ngaphantsi kwe-500 µA.
I-ClearView db photometer ebiza kancinci ye-Process Insights yenza kube lula olu vavanyo ngokusebenzisa iseli yokuhamba edibanisa ngqo kwi-fiber optic probe okanye edlula ukuhamba. I-ClearView db photometer evela kwi-Process Insights inokulinganisa ii-sensors ezimbini ezizimeleyo ze-fiber optic ngaxeshanye, inciphise iindleko zizonke zendawo yokuvavanya.
Olu lwazi lufunyenwe, lwaqinisekiswa kwaye lwahlengahlengiswa kwizixhobo ezibonelelwe yiProcess Insights – Optical Absorbment Spectroscopy.
