多功能原子吸收光譜儀先進(jìn)性能說(shuō)明

發(fā)布時(shí)間:2015/2/3點(diǎn)擊次數(shù):1463
 多功能原子吸收光譜儀先進(jìn)的性能包括:
革新性的-不對(duì)稱調(diào)制技術(shù),樣品與參比光束時(shí)間比采用2:1設(shè)計(jì),,減小了40的噪音。 
超脈沖背景校正方式每秒樣品測(cè)定次數(shù)達(dá)200次(大多數(shù)校正方式為50次/秒),是目前為止zui快的背景校正技術(shù)。測(cè)量總吸光值與背景值之間的延遲時(shí)間只有1毫秒,使背景校正誤差大大降低,內(nèi)插法背景測(cè)量,使背景測(cè)量精度得到進(jìn)一步改善。這種背景校正系統(tǒng)具有zui強(qiáng)的扣背景能力,可校正到2.bs吸光度。先進(jìn)的背景校正技術(shù)-*真正可以應(yīng)用于石墨爐多功能原子吸收光譜儀AAS的氘燈系統(tǒng) 
GBC Sens AA Dual從不使用透鏡,光學(xué)系統(tǒng)全部元件均有石英涂層,全反射鏡片確保準(zhǔn)確聚焦,在全波長(zhǎng)范圍內(nèi)保持高能量的光通量,降低了能量的損失,全封閉光學(xué)系統(tǒng)防塵、防腐蝕性氣體 
內(nèi)置觸摸屏P4計(jì)算機(jī)(256M RAM,40GB硬盤(pán)),Windows XP操作系統(tǒng),21世紀(jì)操作軟件 
出眾的光學(xué)系統(tǒng) 
Ebert-Fastie型單色器,,提高了原子吸收所必需的光源效率及穩(wěn)定性。 
超寬測(cè)定波長(zhǎng)范圍為175~ 900nm,長(zhǎng)焦距333mm,光柵刻線1800線/mm。 
自動(dòng)選擇波長(zhǎng),自動(dòng)對(duì)峰位。自動(dòng)波長(zhǎng)掃描用于火焰發(fā)射法或輔助故障檢修。 
計(jì)算機(jī)控制光譜帶寬0.1~2.0nm(20檔)連續(xù)可調(diào),狹縫高度0.1~2.0nm(20檔)連續(xù)可調(diào),多功能原子吸收光譜儀從而對(duì)靈敏度和分辨率可作出*的優(yōu)化,并可降低高度以便于石墨爐分析時(shí)提高靈敏度和降低干擾。
