dyn-fl-OX-Controller - Optimized LC/ICP-MS coupling


Ref.-Nr. 2335

The invention provides a time-dynamic flow of oxygen for feeding into ICP-MS systems. In coupled LC/ICP-MS systems this allows a solvent gradient to be compensated in the LC. In this case, a dynamic flow of oxygen is firstly optimized empirically at the respective LC gradients - this is started at the same time as the LC/ICP-MS measurement using an appropriate trigger device. A constantly low analyte-oxide-rate and therefore an improved signal-noise ratio are observed as a result of using a parallel optimized oxygen flow.

Commercial Opportunity

Coupled LC/ICP-MS systems are being increasingly used in the field of species analysis. There will be increasing demand in the future for systems that allow compatibility between organic LC solvent gradients and detection using ICP-MS by simple means. The developed system makes a decisive contribution here.
