Ionix 7100
ICP-MS

Description

Ionix 7100 ICP-MS was developed after overcoming key technical challenges in mass spectrometry, including high-temperature gas-flow field control, a multi-stage gradient vacuum system, highsensitivity ion interfaces, distributed collision/reaction cells, and a temperature- and humidity-resistant quadrupole mass analyzer.

The platform supports LC coupling, an on-line argon dilution system, automated rapid injection, oxycombustion, laser ablation, atmospheric direct injection, and organic sample introduction, meeting the needs of a wide range of specialized applications.

IonixMaster software further simplifies operation through a standard method library, automatic tuning, guided workflows, and real-time visual status monitoring, significantly reducing the learning curve for routine laboratory use.
