Analysis of Anions and Oxoanions using Ion Chromatography Mass Spectrometry (IC-MS)
19 Nov 2018Ion Chromatography Mass Spectrometry (IC-MS) is a powerful tool to handle many challenging analytical tasks. Ion chromatography tackles difficult separation problems of various ionic species and typically works with conductivity detection. Mass detection as a secondary independent detector, confirms the identity of analytes in difficult matrices to ensure correct results. Even co-eluting components can be quantified and detection limits are considerably improved. Various ions, such as nitrate, phosphate, perchlorate, thiosulfate or thiocyanate are reliably separated and detected. Difficult matrices like soil or explosion residues can be removed with automated sample preparation techniques (e.g. with Inline Ultrafiltration or Dialysis). The technique is a robust and easy-to-use way to monitor anions and oxoanions in various matrices, e.g. in environmental, post-explosion and semiconductor samples.

940 Professional IC Vario
Metrohm AGWith the 940 Professional IC Vario system, Metrohm sets a new standard in ion chromatography. 940 Professional IC Vario stands for maximum flexibility combined with most easy operation and perfect reliability. Entirely modular by design, the new 940 Professional IC Vario meets your particular requirements while keeping you perfectly flexible. Based on one and the same system, you can configure any IC system you want or need.All solutions – including standards – are produced fully automatically, if desired. Starting with sample injection, the system works completely autonomously. Moreover, it is self- monitoring: All system and method parameters are permanently checked; if any system component should require maintenance, the system tells you so – with a message in plain text.The 940 Professional IC Vario system provides superior reliability of both the system itself and the analytical results produced on it: Because the system is self-monitoring, operator errors are virtually ruled out. You can absolutely rely on your measuring results. Moreover, all results can be traced back to every single step of the analysis and even sample preparation. Thus, even the strictest audits are no reason to worry any more.940 Professional IC Vario Features: Modular high-performance ion chromatography system.
