Hitachi UV Spectrometer U-3900 / 3900H Babban fasali
1, biyan m bukatun ruwa da kuma m samfurin gwaji
● m gani tsarin tabbatar da daidai bincike; (U-3900 guda yayya monochrome, U-3900H biyu yayya monochrome)
● Akwai biyu wavelengths kewayon 190-900nm da 190-1100nm don zaɓar, amfani da PMT detector, saduwa da high hankali gwajin bukatun
● Zaɓi mai yawa na kayan haɗi bisa ga aikace-aikace
● sabon bayanai sarrafawa software UV Solution goyon bayan bambancin your quantitative bincike
● PC mai kula da USB data sadarwa
2, kayan aiki fasaha siffofin:
● Wavelength daidaito: ± 0.1nm
● Absorption gwajin kewayon: -3.8 ~ 3.8Abs (U-3900) -5.5 ~ 5.5Abs (U-3900H)
● Tsarin kwanciyar hankali: 0.0002Abs / h
● tushen layi flatness: ± 0.0003Abs (U-3900? plusmn; 0.0004Abs (U-3900H) (190-850nm)
● hayaniya matakin: ± 0.00005
3, Babban samfurin warehouse haɓaka accessories
Lokacin da ka shigar da wannan babban samfurin warehouse haɓaka kayan haɗi da sauran kayan haɗi a kan U-3900 / U-3000H spectrometer, za ka iya auna nuni halaye na samfurin, polarization halaye da ya haifar da canje-canje na shiga kusurwa, da kuma m samfurin da kuma gani abubuwan da aka yi amfani da 60mm diamita integral ball, za mu iya gwada yaduwa haske na samfurin (yaduwa nuni da yaduwa); Amfani da ingantaccen babban samfurin warehouse, samfurin da aka fi girma zuwa 120mm size za a iya sanya kai tsaye a cikin gwajin; Bugu da ƙari, shigar da 5 ° / 45 ° spectral reflection kayan haɗi don auna cikakken reflection spectrum.
4, cimma wavelength ma'auni na 190nm-1100nm kewayon
Idan canza kusan infrared amsa photoelectric multiplier tube detector, za mu iya auna sha spectrum na 190nm-1100nm. Alal misali, za ka iya kimanta siffofin watsawa a kusan 940nm, wanda yawanci ana amfani da shi don sarrafa nesa. Bugu da ƙari, auna phosphoric acid ya zama yiwuwa a nan.
5, sanye da bambancin gyara concave grating
U-3900 / 3900H spectrophotometer amfani da Seya-Namioka monochrome gauge, shigar da plutonium U-3900 / 3900H spectrophotometer yana da haske mai mayar da hankali da kuma rarraba aiki, tsarin gani yana da ƙarfi, yana amfani da ƙananan madubi kuma yana buƙatar ƙananan hanyoyin haske, don haka za a iya haɓaka ƙarancin ƙarancin haske da hasken gani.
Biyu nau'ikan gani tsarin: monochrome tsarin (U-3900) da biyu monochrome tsarin (U-3900H)
Akwai nau'ikan tsarin daban-daban guda biyu: tsarin monochrome (U-3900) da tsarin monochrome biyu (U-3900H).
Tsarin monochrome ya dace da samfurin ƙananan taro, saboda makamashin hasken kayan yana da ƙarfi fiye da tsarin monochrome biyu. Tsarin dual monochrome ya dace da kayan da ke da yawa saboda yana iya gano ƙananan haske da ke da yawan sha.
