Plasma and Interface
The argon plasma ion source and sampling interface of the ELEMENT 2/XR are at
ground potential
This enables the straightforward coupling of peripherals like HPLC, CE, GC and laser ablation.
The interface reduces the initial kinetic energy spread from ~20 to ~5 eV by capacitively decoupling the plasma from the load coil,using a grounded guard electrode. This reduced energy spread increases the ion transmission and delivers superior
sensitivities at all resolutions.
The ion transfer optics focus the ions from the plasma interface on the entrance
slit of the double focusing analyzer.
The ion transfer optics are designed for low background, highest sensitivity and
minimum mass bias at maximum stability 2
