Chromatography

High-Sensitivity Ion Source
Provides an ion optics system with high transport efficiency and achieves temperature homogenization of the ion source box.

High-sensitivity analysis of chlorpyrifos-methyl (5ppb)

The effect of filament potential on the ion source is reduced by placing more distance between the filament and ion source box, and installing a shield plate. The result is that generated ions are transported more efficiently to the MS. Filament shielding ensures efficient ion transport to the detector while protecting thermally labile compounds.

Overdrive Lens
(Noise Elimination Technology)



The installation of an overdrive lens, in front of the electron multiplier, has reduced the random noise that occurs with ion transmission, improving the S/N ratio. Through the application of a voltage to the lens reduces, the noise component in the vicinity of the lens is reduced, and the effect of focusing ions from the mass filter improves the S/N ratio.
