The ESIA Ar from MAAS Spectrometry, is an isotope ratio mass spectrometer configured for specific target elements, aimed at laboratories who want routine high precision isotope ratio measurements easily and reliably. The collector is easily interchangeable to enable different elements to be targeted. The initial collector has been designed to target Lithium isotopes, and currently a collector is being developed to target Strontium isotopes. Further collector designs for other elements are being developed.

System Overview

The all new DSN Desolvating nebuliser system, a joint development by AJB Instrumentation Ltd and MAAS Spectrometry Ltd is now available. Sold and supported by AJB Instrumentation Ltd and manufactured in the UK by MAAS Spectrometry Ltd.

The DSN is a liquid sample introduction system for ICP-MS applications increasing overall sensitivity whilst reducing oxide and hydride interferences. By combining controlled desolvation with precision gas flow management, the DSN enhances analyte transport efficiency while removing solvent vapours prior to ionization by the plasma.
