Metrohm - Extending the Scope of IC - Hyphenated Techniques
From Ion Chromatography
Interfacing Metrohm ion chromatographs with sophisticated sampling systems on the one hand (PILS, MARGA, and CIC) and/or universal, highly sensitive detection systems (IC-MS, IC-ICP/MS) on the other greatly extends the scope of ion chromatography.
Another option is the combination of Metrohm IC with complementary technologies from our portfolio, such as titration and voltammetry. TitrIC and VoltIC, respectively, enable dedicated multi-parameter analysis on a single system.
Pyrohydrolytic Combustion Ion Chromatography (CIC) extends the range of automated ion chromatography to all kinds of combustible samples.
In CIC, samples are digested by pyrohydrolysis in an oven unit. The resulting gaseous compounds are passed into an absorption solution, which is transferred to a Metrohm ion chromatograph for subsequent injection and analysis.CIC is the preferred method to determine various halogens and sulfur in matrices ranging from solids to viscous, liquid, and gaseous samples.
- For fully automated routine analysis.
- Superior to offline digestion methods both regarding sample throughput and accuracy of results
- Qualification and quantification of concentrations for each of the different halogens
