基于20多年稀有气体质谱仪的经验,Thermo Scientific开发了系列新一代多接收稀有气体质谱仪。它结合创造性的新特征和经过实践验证的成熟的同位素质谱技术,开发了Helix MC Plus、Helix SFT和ARGUS VI三款先进的静态真空稀有气体质谱仪,是多接收静态惰性气体质谱迈进的重要一步。Thermo Scientific HELIX SFT质谱是为氦同位素同时分析及高精度跳峰分析而设计的高分辨、多接收系统,可以同时测定3He和4He,也可以用跳峰模式测量任何稀有气体同位素。
主要特点
· 该系统可同时测量氦同位素,无需跳峰扫描,减少了分析时间,获得了更高的精度和产出效率;
· 丰度灵敏度:由于HELIX SFT独特的设计,质量4对质量3的贡献小于1ppb;
· 体积:HELIX SFT的内部体积约1400cc,这是当前技术的重要提升;
· 分辨率:低质量数接收器,通常用来测定3He,其分辨率大于700,这保证了3He 能够和两个干扰峰HD和H分开;
· 1010Ω/1011Ω/1012Ω/1013Ω放大器拥有不同的动态范围范围使大部分分析都能在长寿命的法拉第接收器上进行。
