Automated Sample Preparation Solution for the Analysis of Total Fluorine, Chlorine, Bromine, and Iodine by Combustion Ion Chromatography Method

Combustion Ion Chromatography

TE Instruments introduces the world’s first independent sample preparation system for Combustion Ion Chromatography analysis: the Xprep C-IC. This unique configuration redefines automated combustion IC analysis through its innovative design and functionalities.

Besides full control over sample combustion, the Xprep C-IC not only collects the oxidized gas stream, but also automatically transfers a fraction of the absorbance solution to any renowned IC system. The ideal solution to cover the increasing demand for analysis of corrosive halogens (Fluor, Chlorine, Bromine, Iodine) and Sulfur compounds (e.g. Sulfate, Sulfite, Thiosulfate) in different matrices. These analytes need to be monitored because they are corrosive, poison catalysts, damage industrial equipment, and are harmful to the environment.

TE Instruments developed a fully automated, extremely compact sample preparation system covering the oxidative pyrohydrolytic combustion, fraction collection, and sample injection towards the IC. The Xprep C-IC can introduce samples both via optimized direct injection (liquids module) and conventional boat-inlet (boat module) into a horizontal furnace. This automated sample-prep solution reduces complexity of sample transfer and significantly improves user convenience.

Common applications

  • Petrochemicals
  • (Bio)Fuels
  • LPG & Gas
  • Lubricants
  • Organic Solvents & Chemicals
  • Polymers (raw materials and final products)
  • Environmental Monitoring (e.g. PFAS Monitoring)
  • Electronic Components (e.g. RoHS compliance)


Xprep C-IC is the only combustion system capable of introducing samples for combustion both via direct injection (liquids module) and boat-inlet (boat module) into a horizontal furnace. Introduction of low boiling liquid samples by direct injection has multiple benefits compared to boat-inlet:

Temperature controlled (500 °C) – Controlled sample dispense of 1 µL/s by automated syringe
• Controlled evaporation of liquid sample into the gas phase, transferred by the inert carrier gas into the combustion zone.
• Controlled sample combustion prevents soot or coke formation, a result of incomplete combustion.
• Improves the repeatability for automated Combustion Ion Chromatography analysis.
• Eliminates the need for a boat program, decreases time of analysis.

Enables a larger sample volume up to 100 µL
• Improves IC-detection limit compared with boat introduction (limited sample volume).
• Multiple injections from the same sample can be introduced, combusted and absorbed for a single IC analysis.
