Timagwiritsa ntchito ma cookies kuti tiwongolere zomwe mukukumana nazo. Mukapitiliza kusakatula tsamba lino, mukuvomereza kugwiritsa ntchito ma cookies. Zambiri.
Imapereka kuyang'anira kosalekeza kwa acetonitrile (ACN): ma gradients amadzi oyenda omwe amagwiritsidwa ntchito pogawanitsa zosakaniza zogwira ntchito za mankhwala pogwiritsa ntchito ClearView db fiber optic filter photometer.
Gwiritsani ntchito spectrophotometer kuti muyese NIR spectrum ya ACN: water mix, sankhani wavelength ya Process Insights process photometer. Zitsanzo zinayesedwa mu 10 mm quartz cuvettes pa 40 ndi 50°C pogwiritsa ntchito chingwe cha fiber optic cha 2 m low OH.
Pa chithunzi 1 chikuwonetsa ma spectra omwe apezeka a magawo 10, 20, 30, 40 ndi 50 olemera. % ya madzi mu acetonitrile. Nsonga yayikulu ya madzi pafupifupi 1420 nm ili kunja kwa kutalika kwa njira yowunikira yosankhidwa ya 10 mm. Njira ina ndikugwiritsa ntchito njira yowunikira ya 1 kapena 2 mm kuti musunge nsonga iyi pamlingo. Ma curve ndi osiyana pang'ono pa kuchuluka kulikonse, kusonyeza momwe kutentha kwa chitsanzo kumakhudzira ma spectrum amadzi.
Sankhani ma wavelength awiri kuti muyesere. Chitsanzo cha calibration chikuphatikizaponso coefficient ya kutentha kwa chitsanzo. Pa chithunzi 2 chikuwonetsa graph ya zotsatira zomwe zanenedweratu komanso zenizeni, ndipo chikuwonetsa calibration yabwino kwambiri yokhala ndi R2 ya 0.9997 ndi cholakwika cha standard cha 0.3% water. Ma coefficients a kutentha ndi kukonza kwa 0.15% water/°C. Chifukwa chake, ClearView db imapereka kulondola kwabwino kwambiri ndi drift ya nthawi yayitali yosakwana 500 µA.
Choyezera kuwala cha ClearView db chotsika mtengo cha Process Insights chimapangitsa kuti muyeso uwu ukhale wosavuta pogwiritsa ntchito selo yoyendera yomwe imalumikizana mwachindunji ndi choyezera kuwala cha fiber optic kapena yodutsa njira yoyendera. Choyezera kuwala cha ClearView db chochokera ku Process Insights chimatha kuyeza masensa awiri odziyimira pawokha a fiber optic nthawi imodzi, kuchepetsa mtengo wonse wa malo oyesera.
Chidziwitsochi chapezedwa, chatsimikiziridwa ndikusinthidwa kuchokera kuzinthu zomwe zaperekedwa ndi Process Insights - Optical Absorbment Spectroscopy.
Kuti mudziwe zambiri pa gwero ili, pitani ku tsamba la Process Insights - Optical Absorbment Spectroscopy.

Mu kuyankhulana uku, AZoM ikulankhula ndi Brandon Van Leer, Woyang'anira Zamalonda Wamkulu, ndi Eric Görgen, Woyang'anira Zamalonda Wamkulu, Thermo Fisher Scientific, za njira yatsopano ya CleanMill broadband ion beam. Akukambirana za momwe ntchito ndi kudzoza kwa kupanga malondawa kunathandizira.
Pamaso pa msonkhano wa June Battery Electric Vehicle Architectures USA, AZoM idafunsa H. Yigit Cem Altintas wa Ford Otosan za mbiri ya kampaniyo ndi momwe idzasinthire kuti ikwaniritse zovuta zatsopano za kusintha kwa magetsi a magalimoto.
Mu kuyankhulana uku, AZoM ikulankhula ndi Avantes Product Manager Ger Loop ndi Production Manager Edwin Sportel za AvaSpec-Pacto photon spectrometer yawo yatsopano yamphamvu.
MiDas™ ndi chipangizo choyezera kuchuluka kwa zinthu chomwe chimagwirizana bwino ndi zinthu zina mu mndandanda wa MiD kuti chiwonjezere kupanga bwino kwa labu.
AvaSpec-Pacto ndi chipangizo chatsopano champhamvu choyezera kuwala chomwe chinapangidwa ndi Avantes kuti chigwirizane ndi mapulogalamu osiyanasiyana.
X100-FTA yatsopano yochokera ku Testometric yamakampani oyesera chakudya ndi kapangidwe kake ili ndi njira yoyesera ya digito yokhala ndi kulondola kwakukulu komanso kolondola.
