Extending the scope of IC – hyphenated techniques

Hyphenated techniques

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.

930 Metrohm Combustion IC PP

2.930.9010
The 930 Metrohm Combustion IC enables the analysis of halogens and sulfur in flammable samples of all types using inline combustion digestion (pyrohydrolysis) with subsequent ion chromatography determination (Combustion IC). It comprises all required components, e.g., the Combustion Module from Analytik Jena (2.136.0700), the 920 Absorber Module, the 930 Compact IC Flex Oven/SeS/PP/Deg, and the MagIC Net software. If necessary, the 930 Metrohm Combustion IC package can be supplemented with an Autosampler for solid or liquid samples (MMS 5000 Autosampler). The entire analysis, including sample input and sample digestion, is completely automated and is completely controlled by MagIC Net.

IC-MS and IC-ICP/MS coupling

IC-MS / IC-ICP/MS
Combining IC with an electrospray ionization mass spectrometer (ESI-MS) or an inductively coupled plasma mass spectrometer (ICP-MS) solves even complex separation problems while achieving outstanding sensitivities and selectivities. These so-called hyphenated techniques provide valuable information for unambiguous peak identification and are less prone to matrix influences than IC with conductivity detection.

Auto Boat Drive

2.136.0710
The Auto Boat Drive (ABD) automatically guides the sample boats into the combustion oven. The sample can be put into the boat manually or using an appropriate sampler. This product made by Analytik Jena has been specially optimized for coupling with ion chromatographs.

LPG Module

2.136.0740
The LPG Module is a sample injection system for liquefied gases. The module is controlled automatically and moves the respective quantities of gas to the combustion oven for combustion. This product from Analytik Jena has been specially optimized for coupling with ion chromatographs.

Air monitoring

Air pollution is a side effect of rapid industrialization and has become a widespread phenomenon.

When combined with sophisticated sampling systems, Metrohm ion chromatographs are a highly suitable tool for comprehensive monitoring of critical pollution parameters in ambient air.

24/7 air monitoring with MARGA

MARGA (Monitor for AeRosols and Gases in Ambient air) is a dedicated solution for online monitoring of ambient air.

MARGA collects the ionic load (anions and cations) from the aerosol and the gas fraction of a defined volume of ambient air, brings it into solution, and injects it into a dual channel ion chromatograph for subsequent analysis. Learn more about MARGA here.

Particle Into Liquid Sampler (PILS)

The Particle Into Liquid Sampler, or PILS for short, transfers aerosols from a defined volume of ambient air to the aqueous phase.

PILS can be interfaced with any Metrohm ion chromatograph for multi-parameter analysis of aerosols. Learn more about this sampling system here.

Combustion Ion Chromatography

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

CIC complies with the following official standards

  • ASTM D7359-08 Standard Test Method for Total Fluorine, Chlorine and Sulfur in Aromatic Hydrocarbons and Their Mixtures by Oxidative Pyrohydrolytic Combustion followed by Ion Chromatography Detection (Combustion Ion Chromatography, CIC)
  • UOP991-11 Chloride, Fluoride, and Bromide in Liquid Organics by Combustion Ion Chromatography (CIC)
  • ASTM D5987-96(2007) Standard Test Method for Total Fluorine in Coal and Coke by Pyrohydrolytic Extraction and Ion Selective Electrode or Ion Chromatograph Methods
  • ASTM WK 24757 Work item for F, Cl, S in LPG

  • ASTM D7994-17 Standard Test Method for Total Fluorine, Chlorine, and Sulfur in Liquid Petroleum Gas (LPG) by Oxidative Pyrohydrolytic Combustion Followed by Ion Chromatography Detection (Combustion Ion Chromatography-CIC)

Tried and tested applications for CIC

  • Environmentally relevant substances (oil, plastic waste, glass, activated carbon, ...)
  • Electronic components (printed circuit boards, resin, cables, insulation, ...)
  • Fuels (gasoline, kerosene, crude oil, heating oil, coal, butane, propane, natural gas, catalysts, ...)
  • Plastics (polymers such as polyethylene, polypropylene, ...)
  • Coloring agents (pigments, paints, ...)
  • Pharmaceutical products (raw substances, intermediates, finished products, ...)
  • Foods (oils, spices, flavorings and fragrances, ...)

IC/MS and IC-ICP/MS – coupling ion chromatography with mass spectrometry

You can expand the scope of what ion chromatography can do by coupling it with a mass spectrometer (IC-MS) or an inductively coupled plasma mass spectrometer (IC-ICP/MS). As a result, you will benefit from an increased sensitivity and selectivity. And this will allow you to perform determinations for which maximum reliability is a must, for instance the monitoring of toxic impurities (such as haloacetic acids) in drinking water.

In addition to yielding quantitative data, these techniques also provide qualitative information on the sample.
