· Elan 9000不带动态反应池,灵敏度提高;DRC-e和DRC-II均带动态反应池(DRC)技术,DRC-e用CH4作为反应气,主要用在环境、食品等通用行业,DRC-II用NH3作反应气,主要用在半导体行业。
· ELAN 9000/DRC-e的标准配置进样系统为耐腐蚀、高盐的GemClean™的十字交叉雾化器和Ryton™ 高分子惰性材料的Scott双通道雾化室,用HF等消解的土壤、地质、环境、冶金样品可以不经过赶HF酸而直接进样分析。雾化器的使用寿命在3年以上。整个进样系统30秒内清洗效率在1000倍以上。
· 两个机械泵两个分子涡轮泵,抽气速率:>380L/min
· 四极杆调节分辨率:0.3~3amu,在同一方法中在线可调(AutoRes™),可在运行中对不同离子选用不同分辨率(自动调节),扩展分析浓度范围和提高灵敏度。
· DRC技术可以使用H2,He,CH3,NH3,O2,N2O,CO2等气体中的任何一种气体。
· DRC技术消除干扰的能力优于7个数量级。
· 化学分辨率>150,000,是可以消除87Sr-87Rb(分开两离子需要的分辨率287,000),204Hg-204Pb(450,000)等干扰的技术。
· 分析107Ag/109Ag 的同位素比分析精密度优于<0.08%RSD的技术。
· 线性范围:9个数量级。
