Exceptional yet Eco Friendly

An advanced mini-torch design, combined with a redesigned collision/reaction cell, and a high-perfor-
mance quadrupole mass filter result in an environmentally friendly system with superior analytical
performance. Redesigned Collision/Reaction Cell Product

Collision Mode

Inert helium gas is introduced into the cell to selectively attenuate kinetic energies of polyatomic ions
based on their sizes. These low energy ions are removed from the ion beam by applying a bias voltage at
the cell exit. Because fewer by-product ions are generated, it can be used for a wide range of applications.

Quadrupole Mass Filter Collision/Reaction Cell Mini-Torch System
Online Interelement Correction (IEC)

Proprietary Advanced Mini-Torch System Shimadzu’s proprietary online interelement correction (IEC) function is used to correct for spectral
interference that cannot be eliminated by the collision mode. By only measuring one standard sample
an interference correction is calculated and applied to all samples run subsequently.
